Acne in adult women: epidemiological, diagnostic and therapeutic aspects

Abstract

Background: Adult female acne (AFA) is a dermatosis of increasing incidence; hyperandrogenism is present in many cases, but there are patients without hormonal abnormalities.

Objective: To analyze the prevalent characteristics in adult women with acne without hyperandrogenism.

Material and methods: A survey of 226 medical records with AFA complaints was conducted; of these, 116 (51.3%) had a normal hormonal profile and were, therefore, included in the study. We investigated age, ethnicity, clinical profile of acne, complementary exams, previous treatment, prescribed treatment and evolution.

Results: The mean age was 33.9 years and the predominant clinical grade of acne was moderate inflammatory (grade 2). The face was the most affected area. Topical retinoids were the most prescribed drugs, and systemic medication was prescribed to 53.4% of the patients. Total regression was observed in 31 patients (26.7%) within 12 weeks of treatment. Adverse reactions to topical treatment occurred in 21.5% of the patients.

Conclusion: The clinical manifestations of AFA in patients without hyperandrogenism are moderate, with predominance of inflammatory lesions. Treatment is similar to that of acne vulgaris; however, special attention should be taken with more irritating medication since this group appears to be more predisposed to skin irritations.
