    TLDR Topical retinoids effectively improve photodamaged skin.
    The document reviewed the therapeutic mechanisms of topical retinoids in treating photodamaged skin, highlighting studies that demonstrated the efficacy and safety of retinoids like tretinoin, adapalene, and tazarotene. These studies, including randomized controlled trials, showed significant improvements in skin texture, elasticity, and collagen production. The document also discussed the molecular pathways of retinoids, including the regulation of retinoid-mediated signaling and suppression of negative regulators of collagen homeostasis. Additionally, advancements in drug delivery systems, such as lipid-based and polymer-based nanocarriers, were noted for enhancing the absorption and stability of retinoids. Overall, the evidence supported the use of topical retinoids as effective treatments for photodamaged skin.

      community Minoxidil seems logistically impossible and impractical to use

      in Minoxidil  136 upvotes 1 year ago
      The post discusses concerns about the practicality of using Minoxidil foam for hair loss, including the frequency of application, preparation, coverage area, and drying time. Responses suggest that missing a dose isn't detrimental, it can be applied once a day, it works on all hair areas, and it doesn't need to be perfectly dry before application.

      Diffuse hair loss and scalp biopsies

      community Diffuse hair loss and scalp biopsies

      in Research  692 upvotes 3 months ago
      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.
