RESUMO

BACKGROUND: Jawoongo is used to treat and prevent skin issues such as dry and keratinization disorders, burns, trauma, pigmentation, scarring, and inflammatory skin conditions. In this study, the efficacy and safety of 0.47% Jawoongo extract-containing soap (JAUN-CS) were assessed in terms of skin improvement effects such as cleansing, moisturizing, sebum secretion management, and skin elasticity enhancement. METHODS: Twenty healthy adult men and women aged 20-60 years old took part in the study. Before and after using JAUN-CS, the participants were divided into groups, and various skin improvement effects were measured utilizing machines such as the Corneometer, Tewameter TM 300, and Visioscan. A dermatologist analyzed the product's safety in accordance with Frosch & Kligman and the Cosmetic, Toiletry, and Fragrance Association (CTFA) rules. RESULTS: Using JAUN reduced the amount of base and point makeup by 25.7% and 76.7%, respectively. Also, JAUN showed a great facial exfoliation effect by removing the old and lifted skin keratins by 84.7% and 20.3%, respectively. Impurities in facial pores decreased by 58%, too. Furthermore, JAUN increased the moisture content of deep skin and skin surface by 3.5% and 74.0%, and skin elasticity by 2.8%. Skin tone, skin texture, skin radiance, and skin barrier all showed improvements of 3.3%, 20.0%, 15.0%, and 115.2%, respectively. Lastly, cleansing with JAUN successfully enhanced the condition of the youth triangle by 7.6%, while TEWL significantly decreased by 52.7%. Neither the JAUN nor the control group soap showed any adverse reactions, such as erythema or allergies, during the testing period. CONCLUSIONS: The results of this study demonstrated that JAUN is safe for human use and has various skin-improving properties, making Jawoongo a promising natural material for the development of functional cosmetics in the future.

RESUMO

BACKGROUND: Botanical ingredients are widely used in hair- and skin-care products. However, few studies have investigated the effectiveness of botanical products on counteracting sebum synthesis and secretion. OBJECTIVE: To investigate the composition of Lotus corniculatus seed extract (LC) and its potential inhibition of lipogenesis in SZ95 sebocytes and oily human skin. METHODS: The active components of LC solutions were identified by high-performance liquid chromatography (HPLC) and nuclear magnetic resonance (NMR). The in vitro effects of LC were evaluated using SZ95 cells treated with linoleic acid (LA) and dihydrotestosterone (DHT) and incubated with LCs for 24 h and 72 h. Lipogenesis was assessed by Oil Red O and Nile Red staining of the cells. In vivo effects were assessed on 30 subjects with oily skin who were enrolled in a randomized, blank-controlled trial and were treated with LC solution for 6 h and 4 weeks. The skin sebum contents and area on the forehead and cheeks were evaluated using a Sebumeter SM815 and Sebfix sebutape with Visioscan VC98. In addition, VISIA was used to collect half-face photos for analysis. RESULTS: A novel active molecule, 5'-o-rhamnosyl uridine, was identified in LC. LC exhibited a dose-dependent inhibitory effect on LA and DHT-induced lipid synthesis. When 5% LC was applied for 3 h, the skin sebum contents and area were significantly reduced compared with the vehicle control, with an obvious reduction after 6 h. Continued use of the serum containing 5% LC for 4 weeks resulted in a significant reduction in the skin sebum contents and area. No adverse reactions were reported during the study. CONCLUSIONS: Topical application of LC resulted in an immediate and long-lasting reduction of the sebum contents and area of oily human skin by reducing sebaceous lipogenesis through the LA and DHT pathways. This indicates the potential of LC as a new biological treatment for oily skin.


CONTEXTE: Les ingrédients végétaux sont largement utilisés dans les produits de soins des cheveux et de la peau. Cependant, peu d'études ont examiné l'efficacité des produits végétaux dans l'inhibition de la synthèse et de la sécrétion de sébum. OBJECTIF: Étudier les composants de l'extrait de graines de lotus (LC) et son effet inhibiteur potentiel sur la lipogenèse des cellules sébacées SZ95 et de la peau grasse. MÉTHODES: Les composants actifs de la solution LC ont été identifiés par chromatographie liquide à haute performance (HPLC) et par résonance magnétique nucléaire (NMR). Les effets de la LC in vitro ont été évalués à l'aide de cellules SZ95 traitées à l'acide linoléique (LA) et à la dihydrotestostérone (DHT) et incubées avec la LC pendant 24 et 72 heures. Les effets in vivo ont été évalués chez 30 sujets à peau grasse qui ont participé à un essai contrôlé randomisé à blanc et qui ont été traités avec une solution de LC pendant 6 heures et 4 semaines. Le sebumeter SM815 et le sebfix sebutape et le visioscan VC98 ont été utilisés pour évaluer la teneur en sébum et la surface de la peau sur le front et les joues. De plus, des photos de demi - visage ont été recueillies pour analyse à l'aide de VISIA. RÉSULTATS: Une nouvelle molécule active, 5'-o-rhamnosyluridine, a été identifiée dans la LC. La LC a un effet inhibiteur dose - dépendant sur la synthèse lipidique induite par LA et DHT. La teneur et la surface du sébum cutané ont été significativement diminuées par rapport à celles du support photographique après 3 heures d'application de 5% de LC, et significativement diminuées après 6 heures. L'utilization de sérum contenant 5% de LC pendant quatre semaines consécutives a entraîné une réduction significative de la teneur en sébum et de la surface de la peau. Aucun effet indésirable n'a été signalé au cours de l'étude. CONCLUSION: L'application topique de LC peut réduire la production de sébum par les voies LA et DHT, ce qui réduit immédiatement et durablement la teneur en sébum et la surface de la peau huileuse humaine. Cela démontre le potentiel de la LC en tant que nouveau traitement biologique de la peau huileuse.

RESUMO

Facial pore enlargement is considered a significant esthetic and health concern in skincare cosmetics. The pores fulfill the critical function of keeping the skin surface hydrated and protected against microbial infections. The hyperseborrhea, the stress factors, and the hormonal triggers can cause pore size enlargement, causing higher susceptibility of the skin to microbe aggressions and inflammatory reactions. Thus, reducing excessive sebum production and keeping functional pores are two of the most requested activities in skincare cosmetics. A Cirsium eriophorum cell culture extract was investigated for its role in sebum regulation, stratum corneum desquamation, and anti-inflammation. The extract was able to regulate essential markers associated with sebum secretion and pore enlargements, such as the enzyme 5α-reductase, which plays a central role in sebum production, and the trypsin-like serine protease Kallikrein 5, which promotes skin exfoliation and antimicrobial response. Moreover, the extract showed a sebum-normalizing and pore refining activity in individuals having seborrheic or acne-prone skins, suggesting a role of the C. eriophorum extract in rebalancing altered skin conditions responsible for pore enlargement.

RESUMO

BACKGROUND: Guava has benefit phytochemicals that are important for skin-disorder treatment. Nevertheless, its efficacy against oily skin has never been reported. AIMS: The guava toner was developed and clinical evaluated. METHODS: The base toner was formulated, accelerated stability tested, and sensory-evaluated in 10 volunteers. The highest preference base was incorporated with guava extract, stability examined, and skin irritation assessed in 21 volunteers by a single application close patch test. Anti-sebum efficacy was split-face, randomized, single-blind placebo-controlled evaluated in 21 volunteers for 28 days and monitored by Sebutape® on forehead and nose. RESULTS: The stable toner base with the greatest preference (83.20 ± 1.85%) was incorporated with 3%, 4.5%, and 6% of guava extract. The toners were stable with none of skin irritation. The toner with 6% guava extract was selected for efficacy evaluation. Guava toner significantly reduced oiliness of forehead (13.10 ± 3.67%, P < 0.05) and nose (21.43 ± 3.21%, P < 0.001) better than the base toner. The activity on nose was significantly noted (10.72 ± 3.51%, P < 0.05) since the 3rd week of application. CONCLUSIONS: Anti-sebum guava toner was efficiently evidence approved and suitable for a daily application to improve the efficacy.

RESUMO

BACKGROUND: Elevated levels of skin sebum are associated with the growth of Propionibacterium acnes. Intensive degreasing of the skin reduces Propionibacterium acnes but also may cause skin irritation. AIMS: We assessed the degreasing effect and skin tolerability of a botanical face cleanser with hops and willow bark extract and disodium cocoyl glutamate as mild cleansing agent compared to a standard face cleanser with sodium laureth sulfate (SLES). MATERIALS AND METHODS: A total of 21 healthy volunteers with normal to oily skin were enrolled in this study. Both cleansers were applied twice a day on the left or right side of the forehead for 15 days in a standardized manner. Bioengineering measurements were performed on day 8 and 15 and on day 17 after an application break of 48 hours. The sebum level was determined using a Sebumeter® , and skin redness was measured using a Mexameter® . RESULTS: The botanical face cleanser significantly reduced the sebum level (P < .01) in the test area on day 17. The SLES containing cleanser showed a statistically relevant degreasing effect already on day 15, but after the application break the sebum level increased again on day 17. None of the cleansers caused skin irritation as determined by skin redness measurements. CONCLUSIONS: In contrast to the SLES containing cleanser, the botanical skin cleanser with hops and willow bark extract had a continuous degreasing effect without reactive seborrhoe after the treatment break. Skin cleansing without SLES might be advantageous for sensitive skin.

RESUMO

Laboratory monitoring for patients on isotretinoin should include creatinine kinase in athletic males and the more liver-specific gamma glutamyltransferase. There is mounting evidence that acne pathophysiology includes a barrier defect and subsequent microbiome disruption. Avoidance of acne scars with early and aggressive treatment is a more efficient and cost-effective option than subsequent treatment. Laser and light treatments for acne and acne scars are plentiful but poorly supported by evidence-based medicine. The acne pipeline is rich with new chemical entities, new formulations, and combinations of older agents. The gold standard for acne therapy may be changing its face.

RESUMO

We describe a case of unilateral acne which appeared after an episode of facial nerve palsy. An 18-year-old female patient presented with papules and pustules predominantly located on the side where the facial paralysis occurred. The patient suffered right facial paralysis, which was treated with prednisone and kinesiotherapy with massages, electrostimulation, and infrared light. Two weeks later, acne lesions appeared in the area affected by the paralysis. As suggested in other cases of paralysis, including cases of Parkinson's disease and spinal cord injury, an increased sebum excretion rate and the immobility of the affected area are most likely what caused the unilateral acne lesions.

RESUMO

BACKGROUND: Skin care influences skin barrier function during the first postnatal weeks. Although the use of natural oils in preterms has been investigated, there are currently no data comparing the effect of sunflower oil to an emollient on barrier development in healthy term newborns. METHODS: In a prospective, randomized clinical study, 50 healthy full-term newborns aged ≤72 h were randomly assigned to two groups: group baby lotion (L, n=22) and sunflower seed oil (SSO, n=24). The skin barrier function was evaluated in three anatomical areas (front, abdomen, and thigh) by noninvasive assessment of transepidermal water loss (TEWL), stratum corneum hydration (SCH), sebum, and skin pH at inclusion and after five weeks. RESULTS: In both groups, skin pH decreased and SCH increased statistically significantly in all measured areas at W5 compared to baseline. TEWL decreased statistically significantly on the forearm in both groups, on the upper leg in group L, and on the abdomen in group SSO. CONCLUSIONS: Both skin care regimes did not harm skin barrier function adaptation in healthy term neonates during the first five weeks of life.

RESUMO

The skin is fortified with a setup of lipophilic and hydrophilic, enzymatic and non-enzymatic antioxidant systems. Ascorbyl palmitate (AP) and sodium ascorbyl phosphate (SAP) are reported as lipophilic and hydrophilic antioxidants, respectively used for skin care. Present study was aimed to assess the combined AP (in oil phase) and SAP (in aqueous phase) via multiple emulsion (ME1) for controlling sebum secretions in healthy human females. FTIR analysis of AP and SAP was performed for identification. Multiple emulsions (ME1 and control) were prepared and analyzed for physical stability. Antioxidant activities of AP, SAP as well as ME1 (with combination of these compounds) were determined by DPPH method. 11 female volunteers were included in a single-blinded, placebo-controlled, split-face comparative study. Volunteers were instructed to apply ME1 on left cheek while control (without AP and SAP) on right cheek, for a period of 90 days. A non-invasive photometric device (Sebumeter®) was used for the measurement of sebum secretions on both sides of the face with subsequent time intervals. A good antioxidant activity of ME1 was observed. ME1 treatments reduced significant facial sebum secretions as compared with control/placebo treatments. It was concluded that combined AP and SAP supplementations to skin proved a promising choice for controlling facial sebum secretions and could be evaluated for undesired oily skin and acne reductions for beautifying the facial appearance.

RESUMO

PURPOSE: The purpose of this study was to compare cutaneous surface parameters in lesional and non-lesional skin of psoriatic patients and in corresponding areas of control subjects. METHODS: Sixty-six psoriatic patients (of any grade of severity, with or without arthritis, without any therapy other than systemic biologic drugs) and 28 healthy controls were enrolled in this observational, case-control study. Exclusion criteria were current or past sebo-psoriasis and seborrheic dermatitis, pustular or erithrodermic psoriasis; treatment with immune-suppressive agents, retinoids, or ultraviolet phototherapy in the last 6 months; topical treatment in the last 2 weeks. Corneometry, sebumetry, and pHmetry were evaluated on non-lesional skin of forehead, cheek, chin and volar region of forearm, and on a psoriatic plaque (on elbow or neighboring areas); in controls, the same areas were considered. RESULTS: Corneometry values were significantly lower in psoriatic plaques vs. elbows of controls. Sebumetry showed significantly higher values in non-lesional forearm skin and plaques of psoriatic patients vs. corresponding areas of controls. pH was significantly lower in all areas in psoriasis. No differences were found between patients treated or not with biologics and with or without arthritis. CONCLUSION: Evaluating surface skin parameters in psoriasis is useful to better understand the etiopathogenic mechanism and could suggest new therapeutic approaches.

RESUMO

Green tea has cosmetic benefits that include activities against androgen disorders. A hair tonic containing green tea for reduction of scalp sebum was developed and clinically evaluated. Stable green tea hair tonics were closed-patch tested and clinically evaluated in 20 volunteers for 28 days by using a Sebumeter ® . Hair tonic base with glycerin and butylene glycol (total 4%) gained the highest consumers' preference was incorporated with green tea extract. All of the products were stable and none caused skin irritation. Green tea hair tonic (2%) significantly (p ≤ 0.024) lowered scalp sebum for 21 and 28 days following the application, suggesting that this topical therapy of scalp greasiness is safe and efficient.

RESUMO

AIMS: Acne is a common skin disease that originates in the sebaceous gland. The pathogenesis of acne is very complex, involving the increase of sebum production and perifollicular inflammation. In this study, we screened the anti-lipogenic material and demonstrated its effect using cultured human sebocytes. MAIN METHODS: Normal human sebocytes were cultured by explanting the sebaceous glands. To evaluate the anti-lipogenic effect, sebocytes were treated with test materials and (14)C-acetate incorporation assay was performed. KEY FINDINGS: To screen the anti-lipogenic materials, we tested the effect of many herbal plant extracts. We found that Angelica dahurica extract inhibited the insulin-like growth factor-1 (IGF-1)-induced sebum production in terms of squalene synthesis in sebocytes. Furthermore, imperatorin isolated from A. dahurica showed remarkable inhibitory effect on squalene production as well as squalene synthase promoter activity. To investigate the putative action mechanism, we tested the effect of imperatorin on intracellular signaling. The results showed that imperatorin inhibited IGF-1-induced phosphorylation of Akt. In addition, imperatorin significantly down-regulated PPAR-γ and SREBP-1, the important transcription factors for lipid synthesis. SIGNIFICANCE: These results suggest that imperatorin has a potential for reducing sebum production in sebocytes, and can be applicable for acne treatment.

RESUMO

Seborrhea, or oily skin, is a very common condition, especially among young people, caused by the increased secretion of sebum by sebaceous glands in the skin. Based on today's knowledge, a regulatory role of various hormones especially androgens is considered for sebaceous gland secretion; but despite significant evidences emphasis on the effects of the gastrointestinal disorders on coetaneous manifestations, the role of gastrointestinal problems in sebum secretion has not been emphasized yet. This study aimed to explain hormonal changes occurring in gastroesophageal reflux disease which may cause changes in sebaceous gland secretion so that, by explaining these communication mechanisms, common investigations between gastroenterology and dermatology can be performed to evaluate the accuracy of this hypothesis.

RESUMO

Sphingomyelin (SM), an essential phospholipid for the skin, is contained largely in the milk fat globule membrane surrounding milk fat, concentrated fractions of which are also generated concurrently during the manufacture of dairy products. Such an SM-containing milk phospholipid concentrate (SM-MPC) is useful for investigating the benefits of dietary SM. Here, we examined the effect of consuming SM-MPC on the condition of skin in a double-blind, placebo-controlled, randomized trial. Ninety-six healthy subjects aged 20 to 39 yr with low skin hydration were randomly assigned to 3 groups: a high-SM group supplemented with SM-MPC at a dose equivalent to 10 mg/d of SM, a low-SM group supplemented with SM-MPC equivalent to 5 mg/d of SM, and a placebo group fed a vehicle composed of olive oil and beeswax. During daily supplementation for 12 wk, parameters related to the condition of skin were evaluated at baseline and every 3 wk. Skin hydration at the heel was significantly increased at wk 9 and 12 in the low-SM group compared with the placebo group. Skin elasticity in the region below the eye was significantly increased at wk 9 in the high-SM group versus placebo. Questionnaire-based subjective perceptions of skin conditions were significantly improved for facial skin moisture at wk 3 and 12, and in the wrinkle around the eyes at wk 9 and 12 in the high-SM group versus placebo. Our results indicate that constant and long-term supplementation with SM-MPC is capable of improving the general condition of skin.

RESUMO

Light-emitting diodes (LED) have been used to treat acne vulgaris. However, the efficacy of LED on sebaceous lipid production in vitro has not been examined. This study investigated the efficacy of 415 nm blue light and 630 nm red light on lipid production in human sebocytes. When applied to human primary sebocytes, 415 nm blue light suppressed cell proliferation. Based on a lipogenesis study using Oil Red O, Nile red staining, and thin-layered chromatography, 630 nm red light strongly downregulated lipid production in sebocytes. These results suggest that 415 nm blue light and 630 nm red light influence lipid production in human sebocytes and have beneficial effects on acne by suppressing sebum production.

RESUMO

BACKGROUND: Pentacyclic triterpenoids improve epidermal barrier function and induce collagen production. Here, their effects on cutaneous aging by means of objective instrumental measurements were elucidated. METHODS: Reconstituted human epidermis, cultivated keratinocytes and fibroblasts were incubated with Terminalia arjuna triterpenes (T. arjuna bark extract), and mRNA and protein expression of various genes was determined using microarray analysis, qRT-PCR and ELISA techniques. Clinical efficacy of T. arjuna bark extract versus vehicle control cream was elucidated in 30 patients and transepidermal water loss (TEWL), skin hydration and elasticity were measured. Another 30 female patients in their postmenopausal phase were treated with a similar regime, and skin sebum content, cutaneous blood microcirculation and skin density/echogenicity were assessed. RESULTS: Incubation with T. arjuna triterpenes increased FGF-2, TSP-1, TGF-ß and CTGF expression, and VEGF secretion in vitro. Elevated lactate dehydrogenase release upon sodium dodecyl sulphate challenge was reversed by the application of T. arjuna bark extract. T. arjuna bark extract decreased TEWL, improved skin moisturization, reduced scaliness and led to significantly improved skin elasticity. Also, increases in blood microflow and skin sebum content as well as improved skin thickness/echogenicity were noted on postmenopausal skin, resulting in visible reduction of sagging skin on the jowls as demonstrated by digital photography. CONCLUSION: T. arjuna bark extract appears as an innovative active ingredient that exerts versatile antiaging properties in vitro and in vivo.

RESUMO

INTRODUCTION: The aim was to compare the treatment effectiveness of intense pulsed light (IPL) and vacuum versus IPL with placebo for mild to moderate comedonal and inflammatory acne. PATIENTS AND METHODS: We randomized 180 patients with mild to moderate comedonal and inflammatory acne into three groups: Group A - 60 patients treated with vacuum and IPL, Group V - 60 patients treated with IPL, and Group 0 (control group) - 60 patients who received topical treatment with Sebium H2O Micellaire Solution. We evaluated the results using the Leeds revised acne-grading system and Cardiff Acne Disability Index. RESULTS: There was a significant reduction in the number of papules, pustules, and comedones in Groups A and V compared with those in the control group (p < 0.001) with a more rapid decrease of the papules from Group A compared with that from Group V. We found an improvement in the clinical aspect (p < 0.001) when we compared Groups A and V with controls. Patients belonging to Group A were more satisfied compared with those belonging to Group V (p = 0.004) and significantly more satisfied compared with those belonging to Group 0 (p < 0.001). In conclusion, we consider that both the devices are efficient, the combination of vacuum and IPL representing a therapeutic option for the comedonal acne.

RESUMO

BACKGROUND: Propionibacterium acnes is a major contributing factor to the inflammatory component of acne. The interaction of P. acnes with keratinocytes leads to an innate immune response via activation of toll-like receptors (TLR2, TLR4) resulting in the production and secretion of pro-inflammatory mediators. SIG1273, an isoprenylcysteine small molecule modulates inflammatory signaling pathways and kills P. acnes. SIG1273 represents a novel cosmetic functional ingredient that provides relief from blemishes in acne prone skin. OBJECTIVE: To assess the keratinocyte response and microbial growth of SIG1273 in vitro and evaluate the tolerability of SIG1273 gel applied topically in acne prone subjects. METHODS: For in vitro studies, human keratinocytes were exposed in culture to live P. acnes and peptidoglycan (PGN) to induce IL-8 production. P. acnes were cultured to determine minimal inhibitory concentration and minimal bactericidal concentration values. A total of 30 subjects were randomized in a double-blind controlled trial receiving 3% SIG1273 gel or vehicle for 6 weeks. Evaluation included inflammatory lesions, noninflammatory lesions, microcomedones, Sebutape scores, and P. acnes counts. RESULTS: In vitro studies demonstrate SIG1273 inhibits P. acnes-induced IL-8 production and inhibits P. acnes growth. SIG1273 gel was well tolerated with no signs of stinging, redness, or itching. Furthermore, improvement in some aspects of acne was observed in subjects applying SIG1273 gel, including inflammatory lesions, microcomedone counts and Sebutape scores. Facial scrubs taken to measure P. acnes colony-forming units showed those applying SIG1273 gel had ~1.0 Log 10 colony reduction over the length of the study, a statistically significantly improvement when compared with vehicle. No significant effects above vehicle were observed for noninflammatory lesions. CONCLUSIONS: SIG1273 represents a novel cosmetic functional ingredient that provides a safe dual modulating benefit to individuals with acne prone skin by reducing P. acnes counts and reducing inflammation.
