    GlossaryUltraviolet Radiation (UV Light Exposure)

    invisible electromagnetic radiation with shorter wavelengths than visible light

    Ultraviolet Radiation (UVR) is a type of electromagnetic radiation that comes from the sun and artificial sources like tanning beds. It has shorter wavelengths than visible light, making it invisible to the human eye, but it can cause skin damage, sunburn, and increase the risk of skin cancer. UVR is also used in medical and industrial applications, such as sterilizing equipment and treating certain skin conditions.

      community Verteporfin and Microneedling

      in Treatments 5 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.
