Unveiling the Nuances of Adult Female Acne: A Comprehensive Exploration of Epidemiology, Treatment Modalities, Dermocosmetics, and the Menopausal Influence.

Previously considered a skin disease exclusively affecting adolescents, characterized by inflammatory and non-inflammatory skin lesions, acne vulgaris is now increasingly observed in adult life, including post-menopause. Today, adult female acne (AFA) is a common chronic inflammatory disease of the pilosebaceous unit, with polymorphic lesions presenting as open or closed comedones, papules, pustules, and even nodules or cysts, often with the presence of sequelae. AFA may persist from adolescence or manifest de novo in adulthood. Its etiology is multifactorial, involving genetic, hormonal, dietary, and environmental factors, yet still incompletely understood. Increased sebum production, keratinocyte hyper-proliferation, inflammation, and reduced diversity of Cutibacterium acnes strains are the underlying disease mechanisms. During menopausal transition, a relative increase in androgen levels occurs, just as estrogens begin to decline, which can manifest itself as acne. Whereas most AFA exhibit few acne lesions with normo-androgenic serum levels, baseline investigations including androgen testing panel enable associated comorbidities to be eliminated, such as polycystic ovarian syndrome, congenital adrenal hyperplasia, or tumors. Another interesting feature is AFA's impact on quality of life, which is greater than in adolescents, being similar to other chronic diseases like asthma. The therapeutic approach to AFA depends on its severity and associated features. This review investigates the intricate facets of AFA, with a specific focus on incidence rates, treatment modalities, and the curious impact of menopause. Utilizing insights from contemporary literature and scientific discussions, this article seeks to advance our understanding of AFA, offering new perspectives to shape clinical practices and improve patient outcomes.

Acne treatment challenges - Recommendations of Latin American expert consensus.

BACKGROUND: Acne is a chronic inflammatory disorder of the pilosebaceous unit that is associated with a negative impact on quality of life, causing anxiety, depression, and poor self-esteem. The treatment of acne is not simple and presents some new challenges. This article addresses important issues faced by dermatologists on their daily, some of them specific for Latin America. OBJECTIVE: To discuss daily practice recommendations when managing acne patients. METHODS: A literature review was conducted by a group of eight experts with extensive experience in the field of acne. The results of the data review were presented at an initial kick-off meeting to align the consensus topics. Two e-surveys using the Delphi methodology and an interim group webinar meeting were held. RESULTS: The expert panel reached a consensus on all proposed key statements, providing scientific support to help dermatologists and healthcare providers make acne management decisions on topics that can be challenging in the everyday practice of dermatology, such as the characteristics of Generation Z or the importance of the maintenance phase of adult acne treatment. CONCLUSION: This article provides current recommendations for managing acne patients. The high level of agreement achieved based on the latest evidence supports the best acne therapeutic choices in both established topics and new important issues that have emerged in recent years, such as the impact of social media, Generation Z characteristics, and transgender male patient specifics.

The Personalized Acne Treatment Tool - Recommendations to facilitate a patient-centered approach to acne management from the Personalizing Acne: Consensus of Experts.

Background: Acne, a commonly treated skin disease, requires patient-centered management due to its varying presentations, chronicity, and impact on health-related quality of life. Despite this, evidence-based clinical guidelines focus primarily on clinical severity of facial acne, omitting important patient- and disease-related factors, including ongoing management. Objectives: To generate recommendations to support patient-centered acne management, which incorporate priority and prognostic factors beyond conventional clinical severity, traditionally defined by grading the appearance and extent of visible lesions. Methods: The Personalizing Acne: Consensus of Experts consisted of 17 dermatologists who used a modified Delphi approach to reach consensus on statements regarding patient- and treatment-related factors pertaining to patient-centered acne management. Consensus was defined as ≥75% voting "agree" or "strongly agree." Results: Recommendations based on factors such as acne sequelae, location of acne, high burden of disease, and individual patient features were generated and incorporated into the Personalized Acne Treatment Tool. Limitations: Recommendations are based on expert opinion, which may differ from patients' perspectives. Regional variations in healthcare systems may not be represented. Conclusions: The Personalizing Acne: Consensus of Experts panel provided practical recommendations to facilitate individualized management of acne, based on patient features, which can be implemented to improve treatment outcomes, adherence, and patient satisfaction.

Acne characteristics in Latin American patients and the potential role of trifarotene.

BACKGROUND: Individualization of treatment based on acne type and severity, location, disease burden, and patient preference is required to maximize efficacy, safety, and adherence to therapy. Latin American populations have unique attributes that must be considered as part of this process to improve clinical success and achieve patient goals. Acne is more common among patients with darker skin phototypes, in whom it is often associated with postinflammatory hyperpigmentation and scarring-the most important acne sequelae-potentially due to more frequent and more severe underlying inflammatory processes in this population. DISCUSSION: These data argue for an early and proactive approach to managing acne in these patients with agents that target the inflammatory processes that underlie acne and its sequelae. As a class, retinoids offer a spectrum of activity that may be useful in addressing the unique needs of Latin American populations. CONCLUSION: Trifarotene, a novel, selective retinoid, has been evaluated in relevant patient populations.

Real-World Case Studies Showing the Effective Use of Azelaic Acid in the Treatment, and During the Maintenance Phase, of Adult Female Acne Patients.

Acne Vulgaris is a chronic inflammatory skin disease, and one of the most prevalent inflammatory dermatoses among teenagers, affecting more than >95% of boys and 85% of girls. Adult female acne (AFA) is a subtype of acne, pragmatically defined as affecting women over the age of 25. The clinical presentation of AFA may be distinguished from adolescent acne according to some key clinical and psychosocial characteristics. The etiopathogenic factors and the chronic clinical course that are implicated in AFA make management complex and challenging. A frequent tendency to relapse makes the requirement for maintenance therapy highly likely. Therefore, AFA typically requires a specific, tailored therapeutic approach. This paper presents six challenging case studies that demonstrate the efficacy of azelaic acid gel (AZA) in adult female acne. The six cases use AZA as monotherapy, as part of a combination regimen at treatment initiation, or as maintenance treatment (which is frequently required in this adult population). The positive outcomes achieved in this case series demonstrate that AZA can be efficacious, result in excellent patient satisfaction in mild to moderate adult female acne, and can be effective as a maintenance therapy.

The usefulness of a dermocosmetic containing Myrtus communis extract and azelaic acid for maintenance phase of adult female acne: Results from a randomized exploratory investigator-blinded comparative study.

BACKGROUND: Acne is a very common condition. Currently, there are relatively few studies available to help guidance-based decisions for its long-term management, especially studies with cosmetic care products. We have developed a skin care product dedicated to adult female acne. OBJECTIVES: Evaluate the efficacy and tolerance of the test product containing Myrtus communis extract and azelaic acid compared with a light moisturizing cream (LCM) in adult females in the acne maintenance phase. METHODS: A clinical study was conducted as a Brazilian, multicentre, randomized, investigator-blinded trial in adult females with clear or almost clear facial acne after anti-acne treatment. The test group (26 subjects) applied the test product and the comparative product group (27 subjects) applied LCM. Both groups applied the products twice daily on the whole face. Subjects were evaluated every 4 weeks over 16 weeks. Efficacy was evaluated according to acne relapse; Investigator's Global Assessment (IGA); acne lesions counting; AcneQoL questionnaire; Subject Global change Assessment (SGA) of acne severity; and the number of Post-Inflammatory Hyperpigmentation (PIH) and Post-Inflammatory Erythema (PIE) lesions. Tolerance was assessed according to a 5-point scale. RESULTS: Over 16 weeks, the number of acne relapse was more than double in the comparator compared to the test product group (eight subjects vs. three subjects respectively). There was no statistical difference in the evolution of the mean IGA from baseline between the two groups; however, 85% of subjects were assessed as clear or almost clear in the test product group and 67% in the comparative group. CONCLUSIONS: This study demonstrated the effectiveness topical application of the test product compared to LCM on acne severity in the maintenance phase of adult female acne. Efficacy results after 16 weeks suggested a trend to limit acne relapses and a benefit of the test product in maintaining long-term remission.

Adapalene/benzoyl peroxide gel 0.3%/2.5% for acne vulgaris

Acne vulgaris is typically treated with a combination of a topical retinoid plus an antimicrobial agent, as recommended by national and international evidence-based guidelines around the globe. Adapalene, a synthetic topical retinoid, is available in two concentrations (0.1% and 0.3%) and in once-daily fixed-dose combinations with benzoyl peroxide (BPO) 2.5%. Adapalene 0.3%/BPO 2.5% is approved for use for moderate-to-severe acne with proven efficacy, good safety and tolerability across a spectrum of patient variables (different ages, genders, and skin types) and disease severity. While some patients experience issues with transient tolerability during retinoid and BPO therapy, it is our clinical experience that good patient education to set expectations and provide strategies to minimize irritation can overcome the majority of issues. This article reviews the data supporting the use of adapalene 0.3%/2.5% in practice, including the complementary mechanism of action of adapalene and BPO, clinical data from a range of settings, and key aspects of patient education.

Agathisflavone, a natural biflavonoid that inhibits SARS-CoV-2 replication by targeting its proteases.

Despite the fast development of vaccines, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) still circulates through variants of concern (VoC) and escape the humoral immune response. SARS-CoV-2 has provoked over 200,000 deaths/months since its emergence and only a few antiviral drugs showed clinical benefit up to this moment. Thus, chemical structures endowed with anti-SARS-CoV-2 activity are important for continuous antiviral development and natural products represent a fruitful source of substances with biological activity. In the present study, agathisflavone (AGT), a biflavonoid from Anacardium occidentale was investigated as a candidate anti-SARS-CoV-2 compound. In silico and enzymatic analysis indicated that AGT may target mainly the viral main protease (Mpro) and not the papain-like protease (PLpro) in a non-competitive way. Cell-based assays in type II pneumocytes cell lineage (Calu-3) showed that SARS-CoV-2 is more susceptible to AGT than to apigenin (APG, monomer of AGT), in a dose-dependent manner, with an EC50 of 4.23 ± 0.21 µM and CC50 of 61.3 ± 0.1 µM and with a capacity to inhibit the level of pro-inflammatory mediator tumor necrosis factor-alpha (TNF-α). These results configure AGT as an interesting chemical scaffold for the development of novel semisynthetic antivirals against SARS-CoV-2.

Evaluation of Psychological Wellbeing and Social Impact of Combined Facial and Truncal Acne: a Multi-national, Mixed-Methods Study.

INTRODUCTION: Half of the individuals with facial acne develop truncal acne, but the impact of combined facial and truncal acne (CA) on patients' quality of life is poorly researched. METHODS: A 60-min interview of 30 participants with CA was conducted that formed the basis for a cross-sectional survey of 694 adolescents and adults with CA. RESULTS: The main themes identified from the qualitative interviews among CA subjects included acceptability to self and others, social functioning and emotional wellbeing. Feelings of embarrassment, self-consciousness and low confidence were experienced often or all the time by over 50% of participants, and were more frequent in those who perceived their acne to be out of control (P = 0.003). Half of patients reported feeling stigmatised because of their CA, and 65.4% believed that others associated their truncal acne with unhealthy or unhygienic habits. Perceived stigma was associated with more feelings of embarrassment (P = 0.005), self-consciousness (P = 0.034) and low self-confidence (P = 0.017). Overall, 64% participants reported that CA interfered with daily life, 46.4% often or always avoided social interaction, 48.6% were often concerned about talking to unfamiliar people and 47.4% were uncomfortable showing affection. Further, 32% and 24.4% participants ≥ 16 years old avoided dating or having romantic/intimate relationships because of their facial and truncal acne, respectively. Social and leisure activities were more frequently negatively impacted among those with perceived uncontrolled CA than among those with controlled CA. Avoiding undressing in front of spouse/partner/friends/relatives was more commonly reported by participants with perceived uncontrolled truncal acne than by those with controlled truncal acne (90.5% versus 80.6%, P = 0.031). CONCLUSION: CA is associated with considerable psychological morbidity, with several exacerbating (e.g. perceived stigma) and attenuating factors (e.g. acne being perceived as being under control) that should be accounted for in CA management.

Evaluation of psychological well-being and social impact of atrophic acne scarring: A multinational, mixed-methods study.

BACKGROUND: Most people with acne are at risk of developing acne scars, but the impact of these scars on patients' quality of life is poorly researched. OBJECTIVE: To assess the perspective of patients with acne scars and the impact of these scars on their emotional well-being and social functioning. METHODS: A 60-minute interview of 30 adults with acne scars informed and contextualized the development of a cross-sectional survey of 723 adults with atrophic acne scars. RESULTS: The main themes identified in the qualitative interviews included acceptability to self and others, social functioning, and emotional well-being. In the cross-sectional survey, 31.6%, 49.6%, and 18.8% of the participants had mild, moderate, and severe/very severe acne scarring. The survey revealed that 25.7% of the participants felt less attractive, 27.5% were embarrassed or self-conscious because of their scars, 8.3% reported being verbally and/or physically abused because of their scars on a regular basis, and 15.9% felt that they were unfairly dismissed from work. In addition, 37.5% of the participants believed that their scars affected people's perceptions about them, and 19.7% of the participants were very bothered about hiding their scars daily. Moreover, 35.5% of the participants avoided public appearances, and 43.2% felt that their scars had negatively impacted their relationships. LIMITATIONS: The temporal evaluation of the impact was not estimated. CONCLUSION: Even mild atrophic acne scarring can evoke substantial emotional, social, and functional concerns.

Impact of Facial Atrophic Acne Scars on Quality of Life: A Multi-country Population-Based Survey.

BACKGROUND: Acne affects more than 80% of adolescents and young adults, who most often develop acne scars. Supporting data on the effect of acne scars on patient's health-related quality of life (HRQOL) are limited. OBJECTIVE: The aim was to determine how the severity of acne scars impacts the HRQOL of afflicted individuals. METHODS: In this population-based cross-sectional study, 723 adults with facial acne scars but without active acne lesions self-completed the Self-assessment of Clinical Acne-Related Scars (SCARS) questionnaire formulated to investigate degree of acne scarring. The Facial Acne Scar Quality of Life (FASQoL), Dermatology Life Quality Index (DLQI), and Dysmorphic Concern Questionnaire (DCQ) were completed to assess the attitude of these patients toward their scars and the impact of scarring on their HRQOL. RESULTS: The mean (standard error) DLQI score for facial acne scars was 6.26 (0.22). Acne scars were considered a 'very large' or 'extremely large' concern by 19.3% of participants with mild scars as compared to 20.1% and 34.0% of participants with moderate and severe/very severe scars, respectively (P = 0.003). Higher FASQoL scores were associated with increased severity of scarring (P = 0.001). In total, 16.9% of participants had clinical features of dysmorphia (i.e., DCQ > 13). DCQ scores were significantly higher among participants with more severe scarring (mean DCQ score of 8.04 [0.28], 8.40 [0.18], and 10.13 [0.08] among participants with mild, moderate, and severe/very severe acne scars, respectively; P = 0.001). Most commonly reported signs of emotional distress were self-consciousness (68.0%) and worry about scars not going away (74.8%). CONCLUSIONS: This study highlights the significant psychosocial impact of atrophic acne scars in the form of embarrassment and self-consciousness. Individuals with mild scars also expressed significant impact on quality of life that increased with aggravation of scar severity. Patient-reported outcomes provide an insight into the physical, functional, and psychological impact of acne scarring from the patient's perspective.

Impact of facial and truncal acne on quality of life: A multi-country population-based survey.

BACKGROUND: Acne confers an increased risk of physical, psychiatric, and psychosocial sequelae, potentially affecting multiple dimensions of health-related quality of life (HRQoL). Morbidity associated with truncal acne is poorly understood. OBJECTIVE: To determine how severity and location of acne lesions impact the HRQoL of those who suffer from it. METHODS: A total of 694 subjects with combined facial and truncal acne (F+T) and 615 with facial acne only (F) participated in an online, international survey. Participants self-graded the severity of their acne at different anatomical locations and completed the dermatology life quality index (DLQI). RESULTS: The F+T participants were twice as likely to report "very large" to "extremely large" impact on HRQoL (ie, DLQI > 10 and children's DLQI [CDLQI] > 12) as compared with the F participants (DLQI: odds ratio [OR] 1.61 [95% confidence interval {CI} 1.02-2.54]; CDLQI: OR 1.86 [95% CI 1.10-3.14]). The impact of acne on HRQoL increased with increasing acne severity on the face (DLQI and CDLQI P values = .001 and .017, respectively), chest (P = .003; P = .008), and back (P = .001; P = .028). LIMITATIONS: Temporal evaluation of acne impact was not estimated. CONCLUSIONS: Facial and truncal acne was associated with a greater impact on HRQoL than facial acne alone. Increasing severity of truncal acne increases the adverse impact on HRQoL irrespective of the severity of facial acne.

Treatment challenges in adult female acne and future directions.

Introduction: Acne is a chronic, inflammatory, and immune-mediated disease of the pilosebaceous unit, highly prevalent in adolescents. However, an increasing number of adults over 25 years old with facial acne, particularly women, have been observed. It is considered a different disease when compared to acne vulgaris. Face is the mainly involved area with inflammatory lesions and more sensitive skin, pointing out the need of a holistic approach.Areas covered: We performed a comprehensive literature search on PubMed database, up to January 2021, regarding adult female acne. We synthesized data about pathogenesis; differences compared to acne vulgaris; and treatment, with focus in the management challenges and perspectives.Expert opinion: It is essential to value the negative impact on quality of life of adult female acne, independently of severity. The disease has prolonged evolution, and patient might be resilient once the improvement, regardless of the treatment option, will just be noticeable after 3 months. Aggravating factors should be clearly discussed, such as the need of changing many habits, especially lesions manipulation. The therapeutic regimen includes make-up and tailored skin care (considering proneness to sensitivity), while anti-acne drugs should be chosen in accordance with desire to be pregnant, presence of pregnancy or breastfeeding.

Consensus on the use of oral isotretinoin in dermatology - Brazilian Society of Dermatology.

BACKGROUND: Isotretinoin is a synthetic retinoid, derived from vitamin A, with multiple mechanisms of action and highly effective in the treatment of acne, despite common adverse events, manageable and dose-dependent. Dose-independent teratogenicity is the most serious. Therefore, off-label prescriptions require strict criteria. OBJECTIVE: To communicate the experience and recommendation of Brazilian dermatologists on oral use of the drug in dermatology. METHODS: Eight experts from five universities were appointed by the Brazilian Society of Dermatology to develop a consensus on indications for this drug. Through the adapted DELPHI methodology, relevant elements were listed and an extensive analysis of the literature was carried out. The consensus was defined with the approval of at least 70% of the experts. RESULTS: With 100% approval from the authors, there was no doubt about the efficacy of oral isotretinoin in the treatment of acne, including as an adjunct in the correction of scars. Common and manageable common adverse events are mucocutaneous in nature. Others, such as growth retardation, abnormal healing, depression, and inflammatory bowel disease have been thoroughly investigated, and there is no evidence of a causal association; they are rare, individual, and should not contraindicate the use of the drug. Regarding unapproved indications, it may represent an option in cases of refractory rosacea, severe seborrheic dermatitis, stabilization of field cancerization with advanced photoaging and, although incipient, frontal fibrosing alopecia. For keratinization disorders, acitretin performs better. In the opinion of the authors, indications for purely esthetic purposes or oil control are not recommended, particularly for women of childbearing age. CONCLUSIONS: Approved and non-approved indications, efficacy and adverse effects of oral isotretinoin in dermatology were presented and critically evaluated.

Herpes Zoster as a Differential Diagnosis for Ischemia after Facial Hyaluronic Acid Filler.

The use of hyaluronic acid (HA) fillers for facial rejuvenation has grown widely and is now one of the most performed noninvasive cosmetic procedures. Viral infections can occur, albeit rarely. This report describes a 65-year-old female patient with significant fat tissue loss in the malar region who developed herpes zoster after receiving HA filler for facial volumization. We performed volumization with a total of 2mL of HA in one session. Two days after the procedure, the patient began feeling mild pain in the malar region bilaterally and in the right side of the nasolabial fold. Upon physical examination, vesicles and erythema were observed. Due to the possibility of herpes zoster virus (HZV) infection, the patient was treated with valacyclovir. Ultrasonography with arterial and venous Doppler study revealed normal blood flow in the angular artery path and adequate positioning of the filler. After seven days of valacyclovir, the patient had complete resolution of the lesions. Herpes virus reactivation can be caused by direct axon damage by the needle, by tissue manipulation, and by inflammatory reaction. Herpes simplex virus (HSV) is the virus most commonly involved and its incidence does not exceed 1.45 percent of the complication cases, and HZV is even rarer. Reactivation of HZV might mimic tissue ischemia. Ultrasonography is a noninvasive, fast, and useful tool to evaluate vascular impairment and the positioning of the filler.

Agathisflavone, a Biflavonoid from Anacardium occidentale L., Inhibits Influenza Virus Neuraminidase.

BACKGROUND: Neuraminidase inhibitors (NAIs) are the only class of antivirals in clinical use against influenza virus approved worldwide. However, approximately 1-3% of circulating strains present resistance mutations to oseltamivir (OST), the most used NAI. Therefore, it is important to catalogue new molecules to inhibit influenza virus, especially OST-resistant strains. Natural products from tropical plants used for human consumption represent a worthy class of substances. Their use could be stimulated in resource-limited setting where the access to expensive antiviral therapies is restricted. METHODS: We evaluated the anti-influenza virus activity of agathisflavone derived from Anacardium occidentale L. RESULTS: The neuraminidase (NA) activity of wild-type and OST-resistant influenza virus was inhibited by agathisflavone, with IC50 values ranging from 20 to 2.0 µM, respectively. Agathisflavone inhibited influenza virus replication with EC50 of 1.3 µM. Sequential passages of the virus in the presence of agathisflavone revealed the emergence of mutation R249S, A250S and R253Q in the NA gene. These changes are outside the OST binding region, meaning that agathisflavone targets this viral enzyme at a region different than conventional NAIs. CONCLUSION: Altogether our data suggest that agathisflavone has a promising chemical structure for the development of anti-influenza drugs.

Adult female acne: a guide to clinical practice.

BACKGROUND: Acne in women is often associated with anxiety and depression, and may persist from adolescence as well as manifest for the first time in adulthood. Genetic and hormonal factors contribute to its etiopathogenesis, and maintenance treatment is required, usually for years, due to its clinical evolution. OBJECTIVE: To develop a guide for the clinical practice of adult female acne. METHODS: A team of five experts with extensive experience in acne conducted a literature review of the main scientific evidence and met to discuss the best practices and personal experiences to develop a guide containing recommendations for the clinical practice of adult female acne. RESULTS: The group of specialists reached consensus on the main guidelines for clinical practice, providing detailed recommendations on clinical picture, etiopathogenesis, laboratory investigation and treatment of adult female acne. CONCLUSION: Different from teenage acne, adult female acne presents some characteristics and multiple etiopathogenic factors that make its management more complex. This guide provides recommendations for best clinical practices and therapeutic decisions. However, the authors consider that additional studies are needed in order to provide more evidence for adult female acne to be better understood.
