    TLDR Genetics play a role in acne, but how exactly they contribute is not fully understood.
    The 2011 document reviews the genetic predisposition to acne vulgaris, indicating that while the role of genetics is experimentally proven, the exact nature and effects of these genetic factors are not fully understood. It discusses polymorphisms in genes related to inflammation and androgen biosynthesis, such as MUC1, TNF-α, IL-1α, androgen receptor VNTR, and CYP1A1, noting that these may contribute to acne development, although findings are inconsistent across different populations. The document also mentions the IL-1A +4,845 SNP and the CYP17 -34T>C promoter polymorphism, which are associated with acne severity, and the potential role of FGFR2 mutations. It emphasizes the complexity of acne pathogenesis, the influence of environmental factors and lifestyle, and the need for more comprehensive genetic studies to fully elucidate the molecular mechanisms involved in acne.

      Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.

      in Research/Science  63 upvotes 2 years ago
      Dihydrotestosterone (DHT) impacts various skin conditions, including Androgenetic alopecia and seborrheic dermatitis, by causing overactivity in sebaceous glands. Topical medications Tacrolimus and Clobetasol can reduce these inflammatory conditions, and treatments like RU58841, Minoxidil, and Finasteride may also be beneficial.

      community Why Breezula Won’t Work for Everyone.

      in Chat  30 upvotes 2 weeks ago
      Breezula, a new topical hair loss treatment, is expected to be expensive, with an estimated cost of €300 per month, making it less accessible compared to cheaper alternatives like finasteride. Some users discuss the potential for cheaper generics from countries like China and India, while others debate the effectiveness and pricing strategy of Breezula compared to other treatments like minoxidil and RU58841.

      community EMA is re-examining Winlevi (clascoterone at lower concentration)

      in Treatment  9 upvotes 6 months ago
      Clascoterone in Winlevi, a topical AR antagonist, is being re-examined due to concerns about HPA axis suppression in adolescents, but it's unlikely to be banned for adult use in androgenetic alopecia (AGA). The European Medicines Agency recommended refusing Winlevi for acne vulgaris, but this may not affect Breezula's approval for AGA.
