    TLDR Burn scars heal abnormally and more research is needed to find better treatments.
    The document from January 1, 2018, examines the biological responses and healing processes of burn scars, comparing the healing of incisional wounds with primary closure to wounds that heal by secondary intention. It details the role of various cells and growth factors in the healing process and the potential for inducing hair follicle regeneration in burn scars. The document also explores the changes in collagen matrix formation, the impact of cytokines and growth factors, the biophysics of thermal injury, and factors that affect wound healing, such as nutrient deficiencies and blood supply. It discusses the standard treatment of early excision and grafting, the complications of wound infection, and the development of hypertrophic scars, which may regress over time or require surgical intervention. The document differentiates hypertrophic scars from keloids and concludes that hypertrophic scarring represents an abnormal regulation of wound healing, with ongoing research needed to develop effective treatments.

      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.
