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.

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.

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.

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.

A randomized comparative trial of a combined oral contraceptive and azelaic acid to assess their effect on sleep quality in adult female acne patients.

Several studies have reported an increase in the prevalence of adult female acne. This subtype of acne presents particular characteristics, and can be triggered by several factors such as smoking, stress, the use of oily cosmetics and even by poor sleep. Sleep quality is related to well-being and the maintenance of body homeostasis. In addition, several skin diseases present a bidirectional relationship with sleep, demonstrating an important connection between skin and the central nervous system. With this in mind, we aimed to compare the effect of two types of treatment for adult female acne (azelaic acid or a combined oral contraceptive) on sleep quality and on concentrations of stress hormones. Also, we proposed to assess the correlation of sleep and hormonal parameters with acne severity. In order to do this, 32 women underwent a clinical evaluation, completed the Pittsburgh Sleep Quality Index (PSQI) questionnaire and had their blood collected for hormone assays. These procedures were performed at baseline and after 6 months of treatment. At baseline there were no differences between the groups in terms of body mass index, age, acne severity and hormone concentrations. Results showed that both treatments demonstrated effectiveness but that women treated with azelaic acid presented a better sleep quality after the treatment compared to baseline and to the group treated with the combined oral contraceptive. The combined oral contraceptive group presented an increase in cortisol and a decrease in free testosterone concentration in relation to baseline. These data suggest that both azelaic acid and combined oral contraceptive are effective in the treatment of adult female acne but, azelaic acid seems to be a more suitable option for those women who may benefit from a better subjective sleep quality.

Acne vulgaris: an inflammatory disease even before the onset of clinical lesions.

Acne is a chronic self-limited disease, which affects mostly teenagers, without gender difference. In recent years, the incidence has increased in female adults. The factors involved in this epidemiological observation are still under discussion in the literature. Clinically, acne is characterized by different types of lesions. The disease affects the regions rich in sebaceous glands (face, chest and upper back). The clinical lesions are: open and closed comedones, erythematous papules, pustules, nodules and different types of scars. Taking into consideration the general concept of inflammation (redness, pain, heat and loss of function), acne is traditionally classified as non-inflammatory (open and closed comedones) and inflammatory (other primary lesions). With the knowledge advancement this concept seems to be wrong and therefore acne would be an inflammatory disease even before the onset of their clinical lesions.

Pioderma gangrenoso bolhoso e síndrome mielodisplásica / Bullous pyoderma gangrenosum and myelodysplastic syndrome

O pioderma gangrenoso pode apresentar-se como manifestação paraneoplásica. Relata-se um caso de pioderma gangrenoso, da variante bolhosa, acompanhado de bicitopenia, em que foi evidenciado, por meio de mielograma, biópsia de medula óssea e cariótipo, padrão compatível com síndrome mielodisplásica, subtipo citopenia refratária com displasia de multilinhagens. Foi tratado com dapsona, obtendo cicatrização das lesões. O pioderma gangrenoso pode associar-se a doenças sistêmicas, devendo a síndrome mielodisplásica ser considerada nos casos acompanhados de citopenias. Portanto, o pioderma gangrenoso pode ser um marcador cutâneo de doença sistêmica de prognóstico reservado.

Pyoderma gangrenosum can present as a cutaneous manifestation of paraneoplastic syndromes. A case of bullous pyoderma gangrenosum associated with bicytopenia is described. During the complementary investigation, myelogram, bone marrow biopsy and karyotype were performed, and showed a pattern consistent with myelodysplastic syndrome. The patient was treated with dapsone with improvement. Pyoderma gangrenosum can be a manifestation of systemic diseases. The possibility of myelodysplastic syndrome should always be considered in patients with pyoderma gangrenosum associated with cytopenia. Pyoderma gangrenosum could indicate poorer prognosis in patients with systemic diseases.
