RESUMEN

Topical ruxolitinib 1.5% cream (Opzelura®), a Janus kinase (JAK) inhibitor, is the first treatment to be approved in several countries for use in patients aged ≥ 12 years with non-segmental vitiligo. In the identical phase III TRuE-V1 and TRuE-V2 trials, significantly more ruxolitinib cream recipients were able to achieve statistically significant and clinically meaningful facial and total body repigmentation, as well as reductions in vitiligo noticeability, compared with vehicle recipients. Efficacy was sustained in longer-term analyses to week 104 of treatment. Ruxolitinib 1.5% cream was generally tolerable in these trials; the most common treatment-related adverse events were acne, pruritus and exfoliation, all at the application site. As with orally administered JAK inhibitors, topical ruxolitinib carries boxed warnings in the USA for serious infections, mortality, malignancy, major adverse cardiovascular events (MACE) and thrombosis, although the incidences were low with topical application. Thus, topical ruxolitinib 1.5% cream is an effective and generally tolerable treatment option for patients aged ≥ 12 years with non-segmental vitiligo.


Non-segmental vitiligo is a chronic autoimmune disease where the skin throughout the body loses its pigmentation, and is usually managed with topical therapies, light therapy or surgery. Topical ruxolitinib 1.5% cream (Opzelura®) is the first treatment approved in several countries for patients aged ≥ 12 years with non-segmental vitiligo. It inhibits Janus kinase (JAK) proteins, reducing the destruction of skin pigment-producing cells. In two clinical trials, significantly more ruxolitinib cream recipients achieved significant and meaningful skin repigmentation compared with patients who received a non-medicated cream; these results were sustained to week 104 of treatment. Ruxolitinib 1.5% cream was generally tolerable; the most common treatment-related adverse events were acne, itchiness and exfoliation, all at the application site. Topical ruxolitinib has special warnings in the USA for major adverse cardiovascular events (MACE), blood clots, serious infections, death and cancer (associated with the use of oral JAK inhibitors), although incidence rates for these adverse events were low in the clinical trials. Topical ruxolitinib 1.5% cream is an effective and generally tolerable treatment option for patients aged ≥ 12 years with non-segmental vitiligo.

RESUMEN

INTRODUCTION: Infraorbital hyperpigmentation represents one of the most prevalent conditions in cosmetic dermatology. To treat this condition, many patients prefer natural remedies. This study explored the efficacy of topical castor oil cream in treating patients with infraorbital hyperpigmentation. METHODS: We conducted an exploratory single-arm clinical trial at the Shahid Faghihi Dermatology Clinic and Molecular Dermatology Research Center of Shiraz University of Medical Sciences, Shiraz, Iran, during 2021-2022. Using the convenience sampling method, we enrolled 25 patients with infraorbital hyperpigmentation. We instructed the patients to apply topical castor oil cream twice daily for 2 months. The darkness, melanin, and erythema levels were evaluated by VisioFace® 1000 D and SkinColorCatch® devices. We used a visual analog scale to assess skin laxity, wrinkles, and patient satisfaction. Data analysis was done with Stata version 14.2. RESULTS: The data of 22 patients with a mean age of 40.92 ± 7.33 years were analyzed. The VisioFace® scores decreased significantly by the end of the study [right eyes: mean difference (MD): -5.63 (95% CI: -7.12 to -4.15), p < 0.001; left eyes: MD: -5.91 (95% CI: -7.46 to -4.36), p < 0.001]. Moreover, castor oil cream significantly reduced the melanin level, wrinkles, and skin laxity in the infraorbital region (p < 0.05). CONCLUSIONS: Castor oil cream seems to be an effective alternative for treating infraorbital hyperpigmentation. Randomized clinical trials are needed to confirm our findings.

RESUMEN

BACKGROUND: Photodynamic therapy (PDT) with 5-aminolevulinic acid (ALA) is a reliable treatment for actinic keratosis (AK), but its effect needs to be enhanced in thick lesions. Plum-blossom needle is a traditional Chinese cost-effective instrument for enhancing the transdermal delivery of ALA. However, whether it could improve the efficacy of AK treatment has not yet been investigated. OBJECTIVE: To compare the efficacy and safety of plum-blossom needle-assisted PDT in facial AK in the Chinese population. METHODS: In this multicenter, prospective study, a total of 142 patients with AKs (grades I-III) were randomized into the plum-blossom needle-assisted PDT group (P-PDT) and control PDT group (C-PDT). In the P-PDT group, each AK lesion was tapped vertically by a plum-blossom needle before the application of 10% ALA cream. In the C-PDT group, each lesion was only wiped with regular saline before ALA cream incubation. Then, 3 hours later, all the lesions were irradiated with light-emitting diode (LED) at a wavelength of 630 nm. PDT was performed once every 2 weeks until all lesion patients achieved complete remission or completed six sessions. The efficacy (lesion response) and safety (pain scale and adverse events) in both groups were evaluated before each treatment and at every follow-up visit at 3-month intervals until 12 months. RESULTS: In the P-PDT and C-PDT groups, the clearance rates for all AK lesions after the first treatment were 57.9% and 48.0%, respectively (P < 0.05). For grade I AK lesions, the clearance rates were 56.5% and 50.4%, respectively (P = 0.34). For grade II AK lesions, the clearance rates were 58.0% and 48.9%, respectively (P = 0.1). For grade III AK lesions, the clearance rates were 59.0% and 44.2%, respectively (P < 0.05). Moreover, grade III AK lesions in the P-PDT group required fewer treatment sessions (P < 0.05). There was no significant difference in the pain score between the two groups (P = 0.752). CONCLUSION: Plum-blossom needle tapping may enhance the efficacy of ALA-PDT by facilitating ALA delivery in the treatment of AK.

RESUMEN

BACKGROUND: Ginkgo biloba (GB) leaves extract is known to possess potent antioxidants and other bioactivities such as improved skin conditions and rejuvenation. OBJECTIVE: This study aimed to develop a cosmeceutical preparation to utilize the strong antioxidant potential of GB leaves as part of the skincare formulation. METHODS: Cream incorporated GB (GBC) was prepared by mixing the obtained extract with stearic acid-sodium hydroxide components in an emulsion format. The obtained GBC was characterized for GB contents, uniformity, pH, compatibility, stability, and skin's human application. RESULTS: A homogeneous, physically, and chemically stable, with pH near the skin pH and shiny cream, was obtained. The prepared cream was easy to rub and pearly in appearance. It was effective and safe during the two-week trial conducted on human volunteers according to clinical trial registry protocols. The cream scavenged free radicals in DPPH assay tests. The cream incorporated GB made the skin more spirited and tauter. Furthermore, the wrinkles were reduced and the skin was renewed vigor. CONCLUSION: The GBC worked at the topical level and provided benefits when applied daily for the trial duration. The formulation also provided visually observable anti-wrinkle effects on the skin, with visible improvements in the skin's shape and texture. The prepared cream can be used to rejuvenate the skin.

RESUMEN

Opuntia ficus-indica (L.) Miller (OFI), belonging to the family Cactaceae, is widely cultivated not only for its delicious fruits but also for its health-promoting effects, which enhance the role of OFI as a potential functional food. In this study, the in vitro collagenase and elastase enzyme inhibitory effects of extracts from different parts of OFI were evaluated. The most promising extracts were formulated as creams at two concentrations (3 and 5%) to investigate their effects on a D-galactose (D-gal)-induced skin-aging mouse model. The ethanolic extracts of the peel and cladodes exhibited the highest enzyme inhibitory effects. Cream made from the extract of OFI peel (OP) (5%) and cream from OFI cladodes extract (OC) (5%) significantly decreased the macroscopic aging of skin scores. Only a higher concentration (5%) of OC showed the normalization of superoxide dismutase (SOD) and malondialdehyde (MDA) skin levels and achieved significant improvements as compared to the vitamin E group. Both OC and OP (5%) showed complete restoration of the normal skin structure and nearly normal collagen fibres upon histopathological examination. The Ultra-Performance Liquid Chromatography High Resolution Mass Spectrometry (UHPLC-ESI-TOF-MS) metabolite profiles revealed the presence of organic acids, phenolic acids, flavonoids, betalains, and fatty acids. Flavonoids were the predominant phytochemical class (23 and 22 compounds), followed by phenolic acids (14 and 17 compounds) in the ethanolic extracts from the peel and cladodes, respectively. The anti-skin-aging effects could be attributed to the synergism of different phytochemicals in both extracts. From these findings, the OFI peel and cladodes as agro-waste products are good candidates for anti-skin-aging phytocosmetics.

RESUMEN

The presence of phenobarbital and formaldehyde in drugs, food, and beverages can lead to various health issues, including inflammation, oncogenesis, and neurological distress. Psychological stress leads to mood fluctuations and the onset of skin inflammation. Skin inflammation has a range of causes, including chemicals, heavy metals, infection, immune-related disorders, genetics, and stress. The various treatments for skin inflammation include medical and cosmetic creams, diet changes, and herbal therapy. In this study, we investigated the effects of Avocom-M and pomegranate seed oil extract (PSOE) against phenobarbital- and formaldehyde-induced skin biochemical changes in rats. We analyzed the constituents of PSOE using gas chromatography-mass spectrometry and inductively coupled plasma-mass spectrometry. We also observed biochemical changes in the skin of human volunteers with and without TROSYD and PSOE as a skin cream. We compared the biochemical changes in human volunteers' skin before treatment and 21 days after the treatment stopped. The outcomes showed an improvement in the rats' biochemical status, due to PSOE and Avocom-M treatment. The human volunteers treated with TROSYD and PSOE showed substantial amelioration of skin inflammation. PSOE, Avocom-M, and TROSYD produced beneficial effects by reducing the levels of cyclooxygenase-2, lipid peroxidation, tyrosinase, hyaluronidase, elastase, collagenase, and nitric oxide in the animals tested on and in human volunteers.

RESUMEN

Psoriasis is a complex inflammatory disease, which can be triggered by the interplay among keratinocytes, various immune cells, and even dermal vascular endothelial cells. Understanding of the key players and cytokine/chemokine messengers involved in the initiation and maintenance of psoriasis has significantly evolved and led to numerous systemic biologic therapies targeting those specific components. These therapies, despite their successes, do not ubiquitously affect all pathogenic cellular pathways. They also carry their risks and may be contraindicated in certain patient populations. Therefore, other therapeutics are still necessary. Tazarotene, a decades-old topical retinoid, has been successfully used for treating cutaneous psoriasis. Its retinoid effect via binding to retinoic acid receptors (RAR)/retinoic X receptors (RXR) alters cellular gene expression of numerous pathogenic cells and leads to a long-standing maintenance effect despite discontinuation - a phenomenon known as remittance. Concurrent use of tazarotene with topical corticosteroids results in reduced incidence of treatment-related adverse events. A fixed-combination lotion containing halobetasol propionate (HP) and tazarotene (HP 0.01%/TAZ 0.045%, Duobrii, Ortho Dermatologics) was developed implementing polymeric emulsion technology that demonstrates efficacy in psoriasis while mitigating adverse events associated with each component alone as monotherapy. In this paper, we review the pathogenesis of psoriasis and illuminate the effect of tazarotene and HP on key cellular pathways. In addition, we review the clinical efficacy of fixed-combination HP 0.01%/TAZ 0.045% lotion in psoriasis as well as its long-term treatment maintenance, applicability in skin of color, and beneficial economic impact for patients and healthcare stakeholders. As HP 0.01%/TAZ 0.045% lotion is safe and exhibits excellent efficacy, it should be within the therapeutic toolbox for every psoriasis patient.J Drugs Dermatol. 2023;22:1(Suppl 1):s3-10.

RESUMEN

Mosquito-borne infections like dengue, malaria, chikungunya, etc. are a nuisance and can cause profound discomfort to people. Due to the objectional side effects and toxicity associated with synthetic pyrethroids, N,N-diethyl-3-methylbenzamide (DEET), N,N-diethyl phenylacetamide (DEPA), and N,N-di ethyl benzamide (DEBA) based mosquito repellent products, we developed an essential oil (EO) based mosquito repellent cream (EO-MRC) using clove, citronella and lemongrass oil. Subsequently, a formulation characterization, bio-efficacy, and safety study of EO-MRC were carried out. Expression of Anti-OBP2A and TRPV1 proteins on mosquito head parts were studied by western blotting. In-silico screening was also conducted for the specific proteins. An FT-IR study confirmed the chemical compatibility of the EOs and excipients used in EO-MRC. The thermal behaviour of the best EOs and their mixture was characterized by thermogravimetric analysis (TGA). GC-MS examination revealed various chemical components present in EOs. Efficacy of EO-MRC was correlated with 12% N,N-diethyl benzamide (DEBA) based marketed cream (DBMC). Complete protection time (CPT) of EO-MRC was determined as 228 min. Cytotoxicity study on L-132 cell line confirmed the non-toxic nature of EO-MRC upon inhalation. Acute dermal irritation study, acute dermal dose toxicity study, and acute eye irritation study revealed the non-toxic nature of EO-MRC. Non-target toxicity study on Danio rerio confirmed EO-MRC as safer for aquatic non-target animals. A decrease in the concentration of acetylcholinesterase (AChE) was observed in transfluthrin (TNSF) exposed Wistar rats. While EO-MRC did not alter the AChE concentrations in the exposed animals. Results from western blotting confirmed that Anti-OBP2A and TRPV1 proteins were inhibited in TNSF exposed mosquitoes. Mosquitoes exposed to EO-MRC showed a similar expression pattern for Anti-OBP2A and TRPV1 as the control group. In silico study revealed eight identified compounds of the EOs play significant roles in the overall repellency property of the developed product. The study emphasizes the mosquito repellent activity of EO-MRC, which could be an effective, eco-friendly, and safer alternative to the existing synthetic repellents for personal protection against mosquitoes during field conditions.

RESUMEN

The exposome has an impact on skin from life-long exposure. Acute short-term exposure to exposome stressors can also alter skin functions such as skin physical barrier and immune defenses, leading to skin dryness, sensitivity, flares of inflammatory skin conditions, or viral reactivations. Probiotics are defined as live microorganisms, which, when administered in adequate amounts, confer a health benefit on the host. An extract produced by lysing Vitreoscilla filiformis (VfeV) cultured in Vichy volcanic mineralizing water (VVMW) has properties of probiotic fractions. In this review, we present in vivo and ex vivo studies with a dermocosmetic formulation containing 80% VVMW, 5% VfeV, 4% niacinamide (vitamin B3), 0.4% hyaluronic acid, and 0.2% vitamin E (M89PF) to evaluate the clinical efficacy in preventing and repairing stressed skin. Skin barrier benefits of M89PF were shown in studies after the skin was exposed to sudden thermal changes, after skin irritation by tape stripping, and in sleep-deprived women. M89PF significantly accelerated skin renewal compared to untreated skin. Skin antioxidant defense activity of M89PF was shown after exposure to stress from UVA plus cigarette smoke aggression. Skin microbiome recovery after acute stress from a harsh cleanser was significantly better in M89PF-treated skin compared to bare skin. Clinical benefits of M89PF on correcting clinical signs of stressed skin were shown in both Caucasian and Asian women exposed to a stressful lifestyle and various external (pollution, tobacco smoking, solar radiation) and internal (poor sleep, stressful work, unbalanced diet, and alcohol consumption) exposome factors. M89PF also showed depigmenting properties on dark spots in Asian women. Further clinical studies are now warranted to evaluate the efficacy of M89PF as adjuvant care to prevent and repair skin barrier disruption and reinforce skin defenses in skin exposed to acute stresses.

RESUMEN

BACKGROUND: Intertrigo is an inflammatory skin-fold condition. Candida infections may occur concurrently or afterward. Topical corticosteroids may reduce inflammation but exacerbate Candida infections. The treatment is contentious. OBJECTIVE: To evaluate the efficacies and safety of adsorbent lotion containing tapioca starch, spent grain wax, Butyrospermum parkii extract, argania spinosa kernel oil, aloe barbadensis, rosehip oil, and allantoin for the treatment of mild-to-moderate intertrigo, relative to 1% hydrocortisone cream. METHODS: This randomized, double-blinded study enrolled 40 intertrigo patients. Twice daily, 20 patients applied adsorbent lotion while the remainder used 1% hydrocortisone cream. Efficacy evaluation, skin biophysical measurements, skin tolerability, safety, and visual analog scale (VAS) patient-satisfaction scores were evaluated at baseline and Week 2. RESULTS: The adsorbent lotion showed higher complete cure rates for color, partial epidermal loss, papules/pustules/vesicles/patches, dryness, and scaling than the corticosteroid without statistical significance. Adsorbent lotion demonstrated significantly higher reduction in pruritus than the corticosteroid treatment. Reduction of erythema level using Mexameter and VAS patient-satisfaction scores were not statistically different between adsorbent lotion and hydrocortisone cream. No adverse effects or superimposed infections were reported. CONCLUSIONS: The anti-inflammatory efficacies of adsorbent lotion and low-potency steroid were equivalent. The lotion was safe and produced excellent pruritus reduction. Patient satisfaction was high.

RESUMEN

BACKGROUND: The oil of the grass Cyperus rotundus (purple nutsedge) is an effective and safe treatment option for a variety of conditions. It has anti-inflammatory and antipigmenting properties. There have been no clinical trials comparing topical C. rotundus oil with skin-lightening treatments for axillary hyperpigmentation. AIM: To assess the efficacy of C. rotundus essential oil (CREO) in treating axillary hyperpigmentation, and compare with another active treatment hydroquinone (HQ) and a placebo (cold cream) in this study. METHODS: The study included 153 participants, who were assigned to one of three study groups: CREO, HQ group or placebo group. A tri-stimulus colorimeter was used to assess pigmentation and erythema. Two independent experts completed the Physician Global Assessment, and the patients completed a self-assessment questionnaire. RESULTS: CREO had significantly (P < 0.001) better depigmenting effects than HQ. CREO and HQ did not differ significantly in terms of depigmentation effects (P > 0.05); however, there were statistically significant differences in anti-inflammatory effects and decrease in hair growth (P < 0.05) in favour of CREO. CONCLUSIONS: CREO is a cost-effective and safe treatment for axillary hyperpigmentation.

RESUMEN

Abstract Because it promotes the lightening of pigment spots, tyrosinase inhibition is one of the mechanisms of depigmenting cosmetic products. Considering the adverse effects produced by synthetic depigmenting actives, the search for new therapeutic options is desirable, and plant extracts are possible candidates for hyperpigmentation treatment. Glycolic extracts of Cecropia pachystachya Trécul are, therefore, the focus of this study. Its chemical characterization, antioxidant activity, tyrosinase inhibition, and cell viability were evaluated. Glycolic extracts were obtained by macerating the leaves of C. pachystachya in grain alcohol and glycerin or propylene glycol. Both had a similar chemical constitution, the glycerin being more efficient in concentrating phenolic compounds and flavonoids. Analyses by UHPLC-MS detected quinic acid, chlorogenic acid isomers, proanthocyanidin dimers type B and C, catechin/epicatechin, orientin/isoorientin, isoorientin 2"-O-xyloside, vitexin/isovitexin, and rutin. 5-O-caffeoylquinic acid was then quantified was then quantified, with predominance in the extract produced with propylene glycol. These extracts showed a high antioxidant capacity by the method of DPPH, ß-carotene, and nitric oxide. As for depigmenting activity, both extracts were able to inhibit tyrosinase. Cell viability assay also revealed that the extracts could safely be used in concentrations of ≤ 125 µg/mL. Thus, this study demonstrated for the first time that the glycolic extracts of C. pachystachya have promising chemical and biological characteristics for the development of a multifunctional cosmetic with antioxidant and tyrosinase-inhibition activities

RESUMEN

OBJECTIVE: To unearth the clinical efficacy of tacrolimus ointment + 3% boric acid lotion joint Chinese angelica decoction in chronic perianal eczema. METHODS: Patients with chronic perianal eczema admitted to hospital from June 2018 and June 2019 were retrospectively analyzed. Patients in the control group (n = 38) underwent basic therapy with tacrolimus ointment + 3% boric acid lotion, whereas those in the observation group (n = 38) were given oral Chinese angelica decoction on the basis of the above therapy. Patient's baseline information before therapy and clinical symptoms after therapy were observed and compared, including pruritus ani score, anus drainage and damp score, skin lesion score, skin lesion area score, life quality index score, and IL-2, IL-4, and IgE levels in serum. Overall efficacy in the two groups was also evaluated. RESULTS: No significant differences were found in the baseline information between the observation group and control group before therapy. After therapy, pruritus ani score (P = 0.023), anus drainage and damp score (P = 0.041), skin lesion score (P = 0.025), and skin lesion area score (P = 0.035) of patients in the observation group were remarkably lower than those in the control group. Significantly higher release levels of clinical symptoms of patients in the observation group were indicated. With respect to the control group, the life quality score (P = 0.020) and IgE level in serum (P = 0.003) of patients in the observation group were significantly lower, while IL-4 level in serum was significantly higher (P = 0.129). The therapy in the observation group achieved better clinical efficacy. Overall efficacy in the observation group was markedly favorable with respect to the control group. CONCLUSION: With respect to tacrolimus ointment + 3% boric acid lotion, patients with chronic perianal eczema displayed better clinical efficacy after jointly being treated by Chinese angelica decoction.

RESUMEN

Despite advances in diabetes care, impaired diabetic wound healing remains a significant clinical problem. The present study was aimed at developing a novel cream based on Ginkgo biloba extract and investigating its wound healing effect on full-thickness wounds in diabetic rats. The topical formulated oil-in-water emulsion-based cream contains Ginkgo biloba aqueous extract in an amount of about 1% to 5% as an active agent. The prepared formula was subjected to physicochemical assessment and pharmacotechnical characterization. Eighteen alloxan-induced diabetic rats completing full-thickness excisional skin wounds were randomly divided into three groups topically treated with either a normal saline (control group), the reference drug ("Cytol Centella cream®"), and cream based on the Ginkgo biloba extract. The response to treatment was assessed by macroscopic, qualitative, and quantitative histopathological analysis. The prepared formula showed good physicochemical properties. The rheological behavior of the prepared cream followed a non-Newtonian pseudoplastic pattern at different storage temperatures. The cream, which is a macroemulsion with uniform size distribution, remained stable for 6 months. Skin tolerance studies confirmed the compatibility of the cream with the skin. During the experimental trial, the cream based on the Ginkgo biloba-treated group showed significant improvements over the control and reference groups for both general wound appearance and healing dynamics. This increased rate of closure of wounds in diabetic rats was associated with increased collagen synthesis. Our findings showed that the cream could be a promising and innovative topical treatment with Ginkgo biloba extract for the management of acute diabetic wounds.

RESUMEN

Skin care formulations with antioxidants are being widely explored for their benefits to human skin. The purpose of this study was to formulate a stable w/o emulsion containing anthocyanin derived from Malus dosmestica fruit extract and to further explore its beneficial effects on normal human skin. Anthocyanin was extracted using various solvents from the peel of Malus dosmestica fruit. w/o creams containing anthocyanin has been prepared and systematically characterized for various physiochemical properties in terms of stability at varying conditions of storage. An efficacy study has been carried out on 12 male healthy Asian subjects to determine effects of anthocyanin on skin melanin, erythema, skin moisture, trans-epidermal water loss (TEWL) and on skin sebum. Solvent system containing methanol/acetone/water (3.5: 3.5: 3 v/v/v) including 1% formic acid established a best recovery of anthocyanin from fruit peel. W/O emulsions presented promising stability profile when kept at different storage conditions over 90 days period. All skin parameters studied, anthocyanin has been found more efficacious (p<0.05) for its effects on skin melanin and erythema content of skin. It has been shown that a topical application of anthocyanin derived from Malus domestica has substantial potential for human skin system and needs some patient oriented studies could warrant its potential for damaged skin.

RESUMEN

The present study deals with the evaluation of the age-defying potential of topical cream formulations bearing Geranium essential oil/Calendula essential oil-entrapped ethanolic lipid vesicles (ELVs). Two types of cream formulations were prepared, viz., conventional and ELVs spiked o/w creams. Essential oil- (EO-) loaded ELVs were characterized by vesicle size, polydispersity index, encapsulation efficiency, and scanning electron microscopy. The cream formulations were evaluated for homogeneity, spreadability, viscosity, pH, in vitro antioxidant capacity, sun protection factor, and in vitro collagenase and elastase inhibition capacity. Confocal laser scanning microscopy (CLSM) was performed to ascertain skin permeation of conventional and vesicular cream. The results of in vitro antioxidant studies showed that GEO-/CEO-loaded vesicular creams have notable antioxidant capacity when compared to nonvesicular creams. GEO- or CEO-loaded vesicular creams exhibited the highest SPF value 10.26 and 18.54, respectively. Both the EO-based vesicular creams showed in vitro collagenase and elastase enzyme inhibition capacity. CLSM images clearly depicted that vesicular cream deep into the skin layers. From the research findings, the age-defying potential and photoprotective effects of GEO and CEO were confirmed. It can be concluded that ELVs are able to preserve the efficiency of EOs and have the potential to combat skin aging.

RESUMEN

Wheat Germ Oil (WGO), the flour-milling by-product of wheat has essential constituents for skin health care as vitamin E, B-complex, squalene and unsaturated fatty acids. Incorporate WGO into polymers of the cream and ointment bases and evaluate the wound healing potential of these WGO formulations in the rat-animal model. <b>Materials and Methods:</b> WGO creams and ointments were prepared in two concentrations, 10 and 20% and evaluated for storage stability, homogeneity and compatibility using Fourier Transform Infrared (FT-IR) spectrometry. An amount of 0.5 g of the WGO formulations was applied daily to the injured area of the rats back. Wounds were observed for any clinical changes and healing compared to the control animal group. <b>Results:</b> The WGO was compatible with the cream and ointment bases and physically stables over 60 days of storage. The formulations of WGO have induced dose-dependent wound healing properties however the ointment formulations were demonstrating wound healing activity significantly better than the creams at all the intervals of the treatment. Within three weeks, 20% WGO ointment has induced a 90%reduction in the wound size diameter. Also, wounds recovered by 50% in 10 and 14 days of treatment with 20% WGO ointment and cream, respectively. <b>Conclusion:</b> The results revealed that WGO is a potential wound-healing agent from the scope that WGO is a common cosmetic ingredient and available at affordable prices.

RESUMEN

BACKGROUND: Hospitalized preterm infants with compromised skin barrier function treated topically with sunflower seed oil (SSO) have shown reductions in sepsis and neonatal mortality rate (NMR). Mustard oil and products commonly used in high-mortality settings may possibly harm skin barrier integrity and enhance risk of infection and mortality in newborn infants. We hypothesized that SSO therapy may reduce NMR in such settings. METHODS AND FINDINGS: This was a population-based, cluster randomized, controlled trial in 276 clusters in rural Uttar Pradesh, India. All newborn infants identified through population-based surveillance in the study clusters within 7 days of delivery were enrolled from November 2014 to October 2016. Exclusive, 3 times daily, gentle applications of 10 ml of SSO to newborn infants by families throughout the neonatal period were recommended in intervention clusters (n = 138 clusters); infants in comparison clusters (n = 138 clusters) received usual care, such as massage practice typically with mustard oil. Primary analysis was by intention-to-treat with NMR and post-24-hour NMR as the primary outcomes. Secondary analysis included per-protocol analysis and subgroup analyses for NMR. Regression analysis was adjusted for caste, first-visit weight, delivery attendant, gravidity, maternal age, maternal education, sex of the infant, and multiple births. We enrolled 13,478 (52.2% male, mean weight: 2,575.0 grams ± standard deviation [SD] 521.0) and 13,109 (52.0% male, mean weight: 2,607.0 grams ± SD 509.0) newborn infants in the intervention and comparison clusters, respectively. We found no overall difference in NMR in the intervention versus the comparison clusters [adjusted odds ratio (aOR) 0.96, 95% confidence interval (CI) 0.84 to 1.11, p = 0.61]. Acceptance of SSO in the intervention arm was high at 89.3%, but adherence to exclusive applications of SSO was 30.4%. Per-protocol analysis showed a significant 58% (95% CI 42% to 69%, p < 0.01) reduction in mortality among infants in the intervention group who were treated exclusively with SSO as intended versus infants in the comparison group who received exclusive applications of mustard oil. A significant 52% (95% CI 12% to 74%, p = 0.02) reduction in NMR was observed in the subgroup of infants weighing ≤1,500 g (n = 589); there were no statistically significant differences in other prespecified subgroup comparisons by low birth weight (LBW), birthplace, and wealth. No severe adverse events (SAEs) were attributable to the intervention. The study was limited by inability to mask allocation to study workers or participants and by measurement of emollient use based on caregiver responses and not actual observation. CONCLUSIONS: In this trial, we observed that promotion of SSO therapy universally for all newborn infants was not effective in reducing NMR. However, this result may not necessarily establish equivalence between SSO and mustard oil massage in light of our secondary findings. Mortality reduction in the subgroup of infants ≤1,500 g was consistent with previous hospital-based efficacy studies, potentially extending the applicability of emollient therapy in very low-birth-weight (VLBW) infants along the facility-community continuum. Further research is recommended to develop and evaluate therapeutic regimens and continuum of care delivery strategies for emollient therapy for newborn infants at highest risk of compromised skin barrier function.

RESUMEN

Plant tissue culture holds immense potential for the production of secondary metabolites with various physiological functions. We recently established a plant tissue culture system capable of producing secondary metabolites from Aster yomena. This study aimed to uncover the mechanisms underlying the potential therapeutic effects of Aster yomena callus pellet extract (AYC-P-E) on photoaging-induced skin pigmentation. Excessive melanogenesis was induced in B16F10 melanoma cells using α-melanocyte stimulating hormone (α-MSH). The effects of AYC-P-E treatment on melanin biosynthesis inducers and melanin synthesis inhibition were assessed. Based on the results, a clinical study was conducted in subjects with skin pigmentation. AYC-P-E inhibited melanogenesis in α-MSH-treated B16F10 cells, accompanied by decreased mRNA and protein expression of melanin biosynthesis inducers, including cyclic AMP response element-binding protein (CREB), tyrosinase, microphthalmia-associated transcription factor (MITF), tyrosinase related protein-1 (TRP-1), and TRP-2. This anti-melanogenic effect was mediated by mitogen-activated protein kinase (MEK)/extracellular signal-regulated kinase (ERK) and protein kinase B (AKT) phosphorylation. Treatment of subjects with skin pigmentation with AYC-P-E-containing cream formulations resulted in 3.33%, 7.06%, and 8.68% improvement in the melanin levels at 2, 4, and 8 weeks, respectively. Our findings suggest that AYC-P-E inhibits excessive melanogenesis by activating MEK/ERK and AKT signaling, potentiating its cosmetic applications in hyperpigmentation treatment.

RESUMEN

Aging of the skin is a complicated bioprocess that is affected by constant exposure to ultraviolet irradiation. The application of herbal-based anti-aging creams is still the best choice for treatment. In the present study, Citrus sinensis L. fruit peels ethanolic extract (CSPE) was formulated into lipid nanoparticles (LNPs) anti-aging cream. Eight different formulations of CSEP-LNPs were prepared and optimized using 23 full factorial designs. In vivo antiaging effect of the best formula was tested in Swiss albino mice where photo-aging was induced by exposure to UV radiation. HPLC-QToF-MS/MS metabolic profiling of CSPE led to the identification of twenty-nine metabolites. CSPE was standardized to a hesperidin content of 15.53 ± 0.152 mg% using RP-HPLC. It was suggested that the optimized formulation (F7) had (245 nm) particle size, (91.065%) EE, and (91.385%) occlusive effect with a spherical and smooth surface. The visible appearance of UV-induced photoaging in mice was significantly improved after topical application on CSPE-NLC cream for 5 weeks, levels of collagen and SOD were significantly increased in CSPE- NLC group, while levels of PGE2, COX2, JNK, MDA, and elastin was reduced. Finally, The prepared anti-aging CSPE-NLC cream represents a safe, convenient, and promising skincare cosmetic product.
