    TLDR Regenerative medicine shows promise for improving hair and skin but needs more research for standard use.
    Regenerative medicine, which aims to restore damaged tissues, has applications in dermatology such as wound healing, hair restoration, and skin rejuvenation. The most common treatments are platelet-rich plasma (PRP), stem cells, growth factors, and exosomes, but they lack high-quality evidence supporting their use. A study of 71 patients showed significant improvement in hair density with low dose adipose-derived stem cells (ADSCs). A meta-analysis of 17 trials showed a significant increase in hair density with PRP therapy. PRP has also been used with microneedling and fractional carbon dioxide laser for acne scarring, but evidence is limited. Exosomes have potential roles in hair restoration, skin rejuvenation, scar repair, and skin pigmentation. They modulate cellular replication, differentiation, and apoptosis. However, there are challenges such as lack of standardization in isolation, production, yield, and identification. The document concludes that regenerative medicine will play an important role in aesthetics, but more research is needed.

      community Verteporfin and Microneedling

      in Treatments 6 months ago
      Clinical studies by Dr. Barghouthi and Dr. Bloxham indicate that Verteporfin, when used with FUE and FUT hair transplantation methods, shows promise in hair follicle regeneration and minimal scarring due to its ability to inhibit Yes-associated protein (YAP). Microneedling at depths of 3-3.5mm, combined with Verteporfin, could potentially reactivate dormant follicles, although the optimal dosage and application method are still under investigation. Concerns remain about the DHT sensitivity of regenerated follicles, highlighting the need for further research to optimize trauma levels and Verteporfin concentrations to achieve effective and scar-free hair regeneration.

      The conversation humorously discusses hair loss treatments, including Minoxidil, finasteride, RU58841, and topical 17 alpha estradiol, with some users joking about transitioning to female to avoid baldness. The overall tone is satirical, emphasizing self-acceptance and the lengths people might consider for hair restoration.
