RESUMO

BACKGROUND: Silymarin is an antioxidant that can protect against free radicals that cause premature signs of aging and oil oxidation that may contribute to breakouts. AIMS: The objective of these studies was to evaluate a silymarin antioxidant serum alone and in combination with a prescription acne treatment regimen in improving facial appearance in blemish-prone skin.  Methods: Two international studies were conducted. A 12-week study in Brazil enrolled 56 subjects to examine the effect of silymarin antioxidant serum on facial acne. Clinical grading on acne lesions, skin tone, clarity, and postinflammatory hyperpigmentation (PIH) were conducted. In addition, consumer self-assessment, analysis for markers of lipid peroxidation, and sebumeter analysis were completed. Another Unites States (US)/German study enrolled 40 subjects who were on topical prescription acne medications to which silymarin antioxidant serum was added. Acne lesion counts, tolerability, and facial appearance assessments were conducted in this study. RESULTS: The Brazilian study demonstrated a 45% reduction in inflammatory lesions and a 43% reduction in noninflammatory lesions after 12 weeks of silymarin antioxidant serum use. In addition, sebumeter testing showed a 16% reduction in oiliness at week 1. The US/German study showed the benefits of the serum in persons already on prescription acne therapy by reducing facial erythema by 60%, dryness by 49%, and scaling by 67%. CONCLUSION: Silymarin is shown in clinical testing to have significant benefits in reducing lipid peroxidation, oiliness, and PIH, and in improving key markers of skin aging. Additionally, the serum can be used alone or as an adjunctive treatment in acne therapy to further benefit aging, acne-prone skin. J Drugs Dermatol. 2024;23(4):     doi:10.36849/JDD.8120.

RESUMO

INTRODUCTION: Acne vulgaris is one of the most prevalent diseases worldwide with a considerably high cost and a burden on quality of life. There are currently many topical and systemic therapies for acne; however, many are limited by their local adverse event profile. This review provides an update on current, novel Phase I and II trials for acne vulgaris. AREAS COVERED: This review searched the National Institutes of Health US National Library of Medicine online database of clinical trials (ClinicalTrials.gov) for ongoing Phase I and II trials. Only papers discussing novel therapies were discussed, and combinations of previously FDA-approved drugs were excluded. EXPERT OPINION: The current investigational approaches to acne treatment reflect an attempt to mitigate the underlying cause of acne pathogenesis. By targeting key mechanisms involved, studies aim to show long-term improvement with less frequent treatment use. This provides potential for more tolerable treatments with better patient adherence, in turn leading to increased efficacy.

RESUMO

In our pursuit of enhancing acne treatment while minimizing side effects, we developed tailored Adapalene microsponges (MS) optimized using a Box-Behnken design 33. The independent variables, Eudragit RS100 percentage in the polymer mixture, organic phase volume, and drug to polymer percentage, were explored. The optimized formulation exhibited remarkable characteristics, with a 98.3% ± 1.6 production yield, 97.3% ± 1.64 entrapment efficiency, and a particle size of 31.8 ± 1.1 µm. Notably, it achieved a 24 h cumulative drug release of 75.1% ± 1.4. To delve deeper into its efficacy, we evaluated the optimized microspongeal-gel in vitro, in vivo, and clinically. It demonstrated impressive retention in the pilosebaceous unit, a target for acne treatment. Comparative studies between our optimized Adapalene microspongeal gel and marketed Adapalene revealed superior performance. In vivo studies on Propionibacterium acnes-infected mice ears showed a remarkable 97% reduction in ear thickness, accompanied by a significant decrease in inflammatory signs and NF-κB levels, as confirmed by histopathological and histochemical examination. Moreover, in preliminary clinical evaluation, it demonstrated outstanding effectiveness in reducing comedonal lesions while causing fewer irritations. This not only indicates its potential for clinical application but also underscores its ability to enhance patient satisfaction, paving the way for future commercialization.

RESUMO

BACKGROUND: Acne vulgaris (AV) is a prevalent skin condition known for its potential to cause scarring and psychological distress, often leading to diminished self-esteem. While topical and oral treatments are commonly prescribed, some patients experience treatment failure, adverse effects, or contraindications to conventional therapies. In response to these challenges, laser and energy-based device therapies have emerged as promising alternatives for individuals who fall into these categories, showing considerable potential in the treatment of AV. OBJECTIVE: This study aimed to evaluate the long-term efficacy and safety of a nonablative monopolar radiofrequency (NMRF) in treatment of moderate to severe AV. METHODS: Twenty-four patients with moderate to severe AV underwent a series of two NMRF treatment sessions, spaced 4 weeks apart. To evaluate treatment outcomes, live in-person lesion counts and measurements of pore size and volume, and sebum production were quantified using Antera® 3D imaging system, and Sebumeter®, respectively. Patients' self-assessment data regarding degree of improvement and facial oiliness were gathered. Dermatology life quality index (DLQI) questionnaire was utilized to assess the impact of AV on their quality of life. All objective and subjective evaluations were conducted at the baseline, 1 month after the first treatment, and during follow-up visits 1, 3, and 6 months after the last treatment sessions. Adverse effects were also recorded during each visit. RESULTS: Twenty out of the 24 subjects completed the study protocol. The mean inflammatory lesion counts significantly reduced by 42.86% and 45.71% from the baseline at 3 (p = 0.027) and 6 months (p = 0.032) after the second treatment. Sebum excretion likewise significantly decreased from baseline by 11.62% (p = 0.012), 13.37% (p < 0.001), and 21.51% (p = 0.004), 1 month after the first treatment, 1 and 6 months after the second treatment, respectively. The pore volume continued to decrease by 35% (p = 0.003) and 41.5% (p < 0.001) at 1 and 6 months following the final treatment, respectively. The DLQI significantly decreased from 10.00 (interquartile range [IQR]: 6.50-15.00) to 2.00 (IQR: 1.00-4.75), corresponding to 80% improvement of the index, 1 month after the last treatment and was sustained up to the last follow-up visit. Patients' self-assessments on degree of improvement and facial oiliness also significantly improved following NMRF treatments. The treatments were well-tolerated without significant adverse effects. CONCLUSION: NMRF appears to be an effective and safe treatment for inflammatory AV, with therapeutic outcomes persisting up to 6 months after two treatment sessions.

RESUMO

INTRODUCTION: Acne vulgaris (acne) is characterized by both inflammatory and non-inflammatory lesions. Benzoyl peroxide (BPO) 5% is approved to treat acne but may cause skin irritation and/or contact allergy. OBJECTIVES: To compare the benefit in acne of a multitargeted dermocosmetic cream containing salicylic acid, lipohydroxy acid, niacinamide, 2-oleamido-1,3-octadecanediol, piroctone olamine, zinc, Aqua posae filiformis, and thermal spring water (DC-Eff) to BPO 5% gel. MATERIALS AND METHODS: 150 Caucasian subjects (50% female) aged between 18 and 40 years, with mild to moderate acne according to the GEA (Global Evaluation of Acne) grading system were randomized into two parallel groups (DC-Eff or BPO to be applied twice daily for 56 days). IGA (investigator global assessment), GEA, lesion count, clinical signs and symptoms, and subject assessment were evaluated at baseline, and after 28 and 56 days (D28 and D56) of treatment. RESULTS: The responder analyses of the IGA and GEA scores showed that 62.2% and 47.3%, respectively, in the DC-Eff, compared with 50.0% and 36.5%, respectively, in the BPO, had improved by at least one point at D56. Inflammatory, non-inflammatory, and total lesion counts significantly (p < 0.0001) decreased with both products from baseline, with no between-group difference. Subjects considered that their skin was smoother and that DC-Eff was easy to apply. DC-Eff was better tolerated than BPO. CONCLUSIONS: DC-Eff applied twice daily is as beneficial as BPO in improving mild-to-moderate acne. DC-Eff was better tolerated than BPO and highly appreciated.

RESUMO

BACKGROUND: Acne fulminans (AF) is a rare severe acne entity. Although occasionally reported, it is unclear whether AF development is associated with oral isotretinoin treatment. OBJECTIVES: To investigate the occurrence of isotretinoin-associated AF, clinical characteristics and prognosis at follow-up. METHODS: An international, multicentre, retrospective study was performed in eight hospitals following the call of the EADV Task Force on Acne, Rosacea and Hidradenitis Suppurativa (ARHS). Characteristics of patients treated with isotretinoin before the development of AF (isotretinoin-associated acne fulminans, IAF) were compared with non-IAF (NAF). RESULTS: Forty-nine patients diagnosed with AF from 2008 to 2022 were included (mean age 16.4 years, SD 2.9, 77.6% male). Αrthralgias/arthritis occurred in 11 patients (22.9%). AF occurred without any previous acne treatment in 26.5% of the patients. Overall, 28 patients (57.1%) developed AF after oral isotretinoin intake (IAF group), while the remaining 21 patients (42.9%) developed AF without previous oral isotretinoin administration (NAF group). IAF occurred after a median duration of isotretinoin treatment of 45 days (IQR: 30, 90). Patients with IAF were more frequently male compared to patients with NAF (89.3% vs. 61.9%, respectively, p = 0.023). There were no differences in patients with IAF versus NAF in patient age, the duration of pre-existing acne, a family history of AF, the distribution of AF lesions or the presence of systemic symptoms or arthralgias. Regarding the management of AF, patients with IAF were treated more frequently with prednisolone (96.2%) compared to those with NAF (70%; p = 0.033) and less frequently with isotretinoin (32.1%) compared to NAF (85.7%; p < 0.001). At a median follow-up of 2.2 years, 76.4% of patients were free of AF and scarring was present in all patients. CONCLUSIONS: No specific clinical or demographic characteristics of IAF compared with NAF could be detected, a fact that does not support IAF as a district clinical entity.

RESUMO

BACKGROUND: Sebum physiology and its contributions to acne vulgaris (AV) pathophysiology have been long debated. Within the pilosebaceous unit, androgens drive sebocyte production of sebum, comprising mono-, di-, and triglycerides (the latter converted to fatty acids); squalene; cholesterol; cholesterol esters; and wax esters. Upon release to the skin surface, human sebum has important roles in epidermal water retention, antimicrobial defenses, and innate immune responses. AIMS: Alterations in sebum alone and with other pathogenic factors (inflammation, follicular hyperkeratinization, and Cutibacterium acnes [C. acnes] proliferation) contribute to AV pathophysiology. Androgen-driven sebum production, mandatory for AV development, propagates C. acnes proliferation and upregulates inflammatory and comedogenic cascades. RESULTS: Some sebum lipids have comedogenic effects in isolation, and sebum content alterations (including elevations in specific fatty acids) contribute to AV pathogenesis. Regional differences in facial sebum production, coupled with patient characteristics (including sex and age), help exemplify this link between sebum alterations and AV lesion formation. CONCLUSIONS: To date, only combined oral contraceptives and oral spironolactone (both limited to female patients), oral isotretinoin and topical clascoterone (cortexolone 17α-propionate) modulate sebum production in patients with AV. A better understanding of mechanisms underlying sebaceous gland changes driving AV development is needed to expand the AV treatment armamentarium.

RESUMO

A major factor in the pathogenesis of acne is ductal hyperproliferation in the pilosebaceous glands. This takes the form of invisible microcomedones and leads to the subsequent formation of both inflammatory and non-inflammatory clinical lesions. Microcomedones are the initial stage in the cyclical development of acne, so called comedogenesis. Microcomedones can be detected using cyanoacrylate skin surface stripping, electron microscopy, reflection confocal microscopy and other techniques. It has been proposed that the density and the size of microcomedones are positively correlated with acne severity. Thus, the purpose of this review is to summarize the root causes of acne, and suggest that treatment of microcomedones could, at least in part, resolve acne lesions and prevent relapse.

RESUMO

Acne fulminans (AF) is a rare, serious, sudden-onset and long-lasting skin disease that causes scarring of face and body. Standard treatment with combined long-term isotretinoin and prednisolone is not always sufficient and has a well-known propensity for adverse effects leaving an unmet need for improved therapy. Case reports suggest that tumor necrosis factor (TNF)-α inhibitors may play a role in the management of AF. In a 3-year retrospective data collection from two dermatology centers and literature review of clinical cases of acne fulminans treated with anti-TNF-α therapy, three clinical cases and twelve literature cases were identified. A total of five different TNF-α inhibitors have been tested, with adalimumab being the most commonly used. Clinical response was seen after 1 month in 2/3 (67%) clinical cases and 5/12 (42%) literature cases, respectively, and treatment was successful in 2/3 (67%) and 11/12 (92%) after a median 3-7 months. All reported adverse effects were mild and reversible. Anti-TNF-α treatment may provide rapid improvement in patients with AF when initial treatment with isotretinoin and prednisolone fails. However, randomized controlled trials are lacking, and exact dosage and timing need to be explored before clinical implementation.

RESUMO

PURPOSE: Fractional microneedle radiofrequency (FMR) systems are used to treat inflammatory acne and scarring. Nonetheless, few controlled studies have combined this treatment with the traditional ablative fractional laser (AFL). We aimed to assess the safety and efficacy of the combination of FMR and AFL versus AFL alone in treating acne and acne scars. MATERIALS AND METHODS: In this 20-week, randomized, split-face study, 23 Korean patients with facial acne and acne scars underwent FMR and AFL treatments. One half of each patient's face was randomly assigned to receive FMR+AFL, whereas the other half received AFL alone. Treatments were administered in three consecutive sessions at 4-week intervals. This study investigated the severity of inflammatory acne, acne scars, individual lesion counts, depressed scar volumes, as well as patient and physician satisfaction. In addition, five patients underwent skin biopsy, and sebum output was measured. RESULTS: The FMR+AFL treatment demonstrated superior efficacy compared to AFL alone in terms of inflammatory acne and acne scar grading, lesion counts, and subjective satisfaction. The side effects were minimal and well-tolerated in both groups. Immunohistochemical findings from skin biopsy samples revealed that the application of FMR+AFL could induce an inhibitory effect on sebum secretion at the molecular level. CONCLUSION: FMR combined with AFL is a well-tolerated and effective treatment modality for inflammatory acne and acne scarring.

RESUMO

Microencapsulation has received extensive attention because of its various applications. Since its inception in the 1940s, this technology has been used across several areas, including the chemical, food, and pharmaceutical industries. Over-the-counter skin products often contain ingredients that readily and unevenly degrade upon contact with the skin. Enclosing these substances within a silica shell can enhance their stability and better regulate their delivery onto and into the skin. Silica microencapsulation uses silica as the matrix material into which ingredients can be embedded to form microcapsules. The FDA recognizes amorphous silica as a safe inorganic excipient and recently approved two new topical therapies for the treatment of rosacea and acne. The first approved formulation uses a novel silica-based controlled vehicle delivery technology to improve the stability of two active ingredients that are normally not able to be used in the same formulation due to potential instability and drug degradation. The formulation contains 3.0% benzoyl peroxide (BPO) and 0.1% tretinoin topical cream to treat acne vulgaris in adults and pediatric patients. The second formulation contains silica microencapsulated 5.0% BPO topical cream to treat inflammatory rosacea lesions in adults. Both formulations use the same amorphous silica sol-gel microencapsulation technology to improve formulation stability and skin compatibility parameters.

RESUMO

BACKGROUND: Acne has psychosocial effects on patient's quality of life (QoL). This post hoc exploratory analysis of pooled phase 3 data assessed the impact of investigational IDP-126 gel (for moderate to severe acne) on the Acne-Specific Quality of Life Questionnaire (Acne-QoL; exploratory endpoint in the trials).  Methods: A post hoc exploratory analysis using pooled data (N=309; age ≥13 years) was conducted to assess if 1) changes from baseline to week 12 in Acne-QoL domain scores significantly differ by treatment; 2) differences were clinically meaningful, and 3) relative importance of acne severity as measured by the Evaluator's Global Severity Score (EGSS) or lesion counts explains the changes in QoL (Acne-QoL).  Results: Acne-QoL domain scores significantly (P<0.001, each) improved for patients treated with IDP-126 Gel vs vehicle in all four domains (role-emotional [least squares mean difference {LSMean} 4.1], self-perception [LSMean 3.8], acne symptoms [LSMean 2.6], and role-social [LSMean 2.0]). The proportion of responders was significantly higher (P<0.05, each) in the IDP-126 Gel group vs vehicle across Acne-QoL domains, self-perception (odds ratio [OR]: 4.32), acne symptoms (OR: 3.90), role-social (OR: 3.59), and role-emotional (OR: 2.50). Across all Acne QoL domains, the improvement on the EGSS endpoint (53.8-63.3%) was more likely to influence QoL improvements than the inflammatory (20.1-33.4%) and non-inflammatory lesion (9.5-18.7%) counts.  Conclusions: This post hoc exploratory analysis of pooled phase 3 data (moderate to severe acne) suggests that treatment with IDP 126 Gel led to statistically significant and clinically meaningful improvements in QoL and improvement in QoL was primarily influenced by EGSS.J Drugs Dermatol. 2023;22(10):1033-1039      doi:10.36849/JDD.7812.

RESUMO

Polycystic ovarian syndrome manifests acne and alopecia in teenagers and young adult females. To evaluate ovarian morphology and the prevalence of polycystic ovarian morphology (PCOM) in females between the ages of 21 and 45 who are in the reproductive stage and have isolated acne and/or androgenic alopecia. And their association. The present study was done with patients in the age group of 21 to 45 years with acne and/or androgenic alopecia. Modified Ferriman-Gallwey score was used to assess the degree of hirsutism (with score of more or equal to 8 as significant). Grading of acne vulgaris and androgenic alopecia was done by a single observer. Subjects were then evaluated for biochemical investigations of Hormonal assays on day 2 to 7. Transabdominal ultrasonography was performed in the follicular phase to demonstrate the ovarian morphology. In our study isolated androgenic alopecia was present in 28 patients (24.34%). In our study 54 (46.95%) patients out of 115 had combined acne and androgenic alopecia. In our study out of 33 patients with isolated acne 17 (51.5%) had PCO Morphology with grade I, grade II, grade III having prevalence of 46.2%, 53.8% and 57.1% respectively. In our study of the 28 patients with isolated androgenic alopecia 16 (57.1%) had PCOM with grade I, II and III respectively having prevalence of 56.3%, 55.6%, 66.7% with P value of 0.939. Patients with normal ovarian morphology were 12 in number (42.9%). Of the 54 patients with combined acne and androgenic alopecia 32 (59.3%) had PCOM and 22 patients had normal ovarian morphology. Higher overall prevalence was found in patients with combined acne and alopecia (59.3%) than in isolated groups; acne (51.5%), alopecia (57.1%). In our study it was to found that women with dermatological manifestations like acne and androgenic alopecia with regular menstruation. In our study it was found that these women with have high prevalence of PCOS.

RESUMO

BACKGROUND: Acne vulgaris is a worldwide dermatological condition that has a complex pathophysiology in which androgens play an important role. Flutamide is a first-generation non-steroidal antiandrogen that can be used for acne treatment. AIM: To evaluate the potential therapeutic efficacy and safety of topical flutamide in the treatment of acne vulgaris. METHODS: A andomized controlled study included two equal groups, each had 27 patients, with a total of 54 patients with mild to moderate acne vulgaris having inflammatory (papules and pustules) and non-inflammatory (comedones) lesions. For eight weeks, Group (A) received 1% Flutamide topical gel on the face twice daily, whereas Group (B) served as the control group. RESULT: After 8 weeks of topical Flutamide 1% gel application twice daily, there was a significant reduction in papules count, and a highly significant reduction in pustules number from baseline. LIMITATIONS: We recommend that topical Flutamide 1% gel be tried on a larger number of patients with acne vulgaris, for longer therapeutic duration and follow up periods after treatment. CONCLUSION: Patients with acne vulgaris may find topical Flutamide 1% gel to be a viable, efficient, and safe solution with few adverse effects.

RESUMO

OBJECTIVE: This study aimed to observe the fluorescence characteristics of acne inflammatory skin lesions in 5-aminolevulinic acid-based photodynamic diagnosis (ALA-PDD), and discuss the viability of using ALA-PDD to evaluate acne inflammatory skin lesions and explore the advantages of predicting subclinical skin lesions. METHODS: The OBSERV facial skin detector collected photographs of 20 patients before and after optical intra-tissue fiber irradiation photodynamic therapy (OFI-ALA-PDT) in both ALA-PDD and white light patterns. The patients were treated once a week for four consecutive weeks in order to analyze the correlation between the two patterns in recognizing inflammatory skin lesions. RESULTS: Before and after treatment, there was no significant difference between the two patterns for recognizing acne inflammatory skin lesions (p > 0.05). Both patterns demonstrated a strong correlation (r > 0.90) for the recognition of various types of inflammatory skin lesions at different treatment stages. CONCLUSION: ALA-PDD is a feasible method for evaluating acne inflammatory lesions, guiding treatment and judging efficacy. It has advantages in predicting subclinical skin lesions and deserves further study.

RESUMO

Acne is one of the most widespread skin diseases. The acne mechanism is intricate, involving interactions between different types of cells (i.e., sebocytes and macrophages). One of the challenges in studying the mechanism of acne is that current in vitro culture methods cannot reflect the 3D cellular environment in the tissue, including inflammatory stimuli and cellular interactions especially the interactions between sebocytes and immune cells. To solve this issue, we generated an in vitro acne disease model consisting of 3D artificial sebocyte glands and macrophages through the inertial focusing effect method. Using this model, we produced a controllable inflammatory environment similar to the acne pathogenetic process in the skin. The 3D artificial sebocyte glands and macrophages can be separated for analyzing each cell type, assisting the in-depth understanding of the acne mechanism. This study indicates that proinflammatory macrophages promote lipid accumulation and induce oxidative stress in sebocyte glands. Additionally, in an inflammatory environment, sebocyte glands induce macrophage polarization into the M1 phenotype. Employing this model for drug screening, we also demonstrated that, cannabidiol (CBD), a clinically investigated drug, is effective in restoring lipid accumulation, oxidative stress, inflammatory cytokines and macrophage polarization in the acne disease.

RESUMO

Acne diagnosis, severity assessment and treatment follow-up rely primarily on clinical examination. In vivo reflectance confocal microscopy (RCM) provides non-invasively, real-time images of skin lesions with a level of detail close to histopathology. This systematic literature review aims to provide an overview of RCM utility in acne and a summary of specific features with clinical application that may increase objectivity in evaluating this condition. We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for reporting our results. We systematically searched three databases: PubMed, Clarivate and Google Scholar (January 2022). All included studies used RCM to investigate acne in human patients and reported the investigated skin area and type (acne lesions or clinically uninvolved skin), the substance used in the case of treatment. Our search identified 2184 records in the three databases investigated. After duplicate removal, 1608 records were screened, 35 were selected for full-text assessment, and 14 were included in this review. We used the QUADAS-2 tool to evaluate the risk of bias and applicability concerns. RCM was selected as the index test and clinical examination as the reference standard. The total number of patients from all studies was 291, with 216 acne patients and 60 healthy participants aged between 13 and 45 years. The 14 considered studies analysed 456 follicles from healthy participants, 1445 follicles from uninvolved skin in acne patients and 1472 acne lesions. Consistent RCM findings concerning follicles of acne patients reported across studies were increased follicular infundibulum size, thick, bright border, intrafollicular content and inflammation. Our analysis indicates that RCM is a promising tool for acne evaluation. Nevertheless, standardization, a unified terminology, consistent research methods and unitary reporting of RCM findings are necessary. PROSPERO registration number CRD42021266547.

RESUMO

Barrier damage caused by facial acne vulgaris can be magnified by topical medication, such as adapalene (0.3%) and benzoyl peroxide (2.5%)(A/BPO), which utilizes a retinoid to normalize follicular keratinization and BPO to decrease the C. acnes population. Disease-induced irritation combined with topical medication-induced irritation results in dryness and enhanced inflammation leading to lower compliance and increased skin healing time. Ceramide-based moisturizers have documented barrier repair benefits for eczema but have not been studied for acne. The objective of this double-blind study was to measure the impact of acne treatment on skin barrier function and tolerance when paired with a ceramide routine. Participants were prescribed an A/BPO gel once daily. The treatment group received a ceramide-containing foaming facial cleanser and facial lotion, and the control group received basic foaming face wash for twice-daily use. Participant and investigator tolerability and efficacy were evaluated by both ordinal and clinical measures. Acne lesion counts and Investigator’s Global Assessments (IGA) of acne were obtained along with transepidermal water loss (TEWL) measurements for barrier function. TEWL for the treatment group remained significantly lower than the control at all timepoints and significantly improved from baseline by week 12. The treatment group had statistically lower mean investigator scores for dryness at all timepoints. Inflammatory lesion counts were significantly lower for the treatment group. A/BPO damaged the skin barrier, demonstrated by elevated TEWL, contributing to dryness, redness, and scaling. Use of a ceramide-containing cleanser and moisturizer significantly reduced severity and incidence of dryness, erythema, and scaling while more quickly resolving barrier damage and restoring function.

RESUMO

Acne vulgaris is a highly prevalent skin condition caused by androgen-induced elevated sebum secretion, abnormal keratinization, bacterial colonization, and inflammation. Current research indicates a link between acne vulgaris and the metabolic syndrome, a group of disorders that includes obesity, insulin resistance, hypertension, and dyslipidemia. This link is thought to be modulated by excessive concentrations of oxidative stress markers and chronic inflammation, which are included in the pathophysiological mechanisms shared by both conditions. Excessive generation of reactive oxygen species damages cellular components and initiates an inflammatory response, hence promoting the development of both disorders. The current narrative review focuses on the molecular implications of inflammatory, hormonal, and environmental factors in the acne-metabolic syndrome correlation. Furthermore, it outlines the current state of knowledge related to the phyto-therapeutic approach to these conditions as an adjuvant strategy to allopathic treatment, but future multicenter and larger-scale research studies are needed establish new algorithms to be included in the future management of patients with these conditions.
