January 2013
Studysummary This study found that three months of metformin therapy improved acne, hirsutism, and menstrual irregularities in women with PCOS, along with hormonal and ultrasonographic changes. Our plain-language summary of this paper — not a Tressless recommendation.
The study investigated the effects of metformin on acne vulgaris and other hyperandrogenism symptoms in females with PCOS. Out of 33 participants, 25 met the Rotterdam criteria for PCOS, and 17 completed a 3-month metformin therapy (1-1.5 g/day, with minoxidil 2% for severe androgenic alopecia). Results showed significant improvements in weight, waist to hip ratio, acne scores (from 2.37 ± 0.17 to 1.68 ± 0.19), hirsutism scores (from 14.3 ± 1.7 to 12.8 ± 1.8), androgenic alopecia (hair growth in 6 out of 13 subjects), and menstrual regularity (50% had regular cycles). Hormonal levels and ultrasonographic parameters also normalized. The study concluded that dermatologists should consider PCOS in patients with acne vulgaris and treat them with metformin.
