Fibroblast treatment is a non-surgical skin-tightening procedure that targets fibroblasts, which are collagen- and protein-producing cells in the dermis, the layer of skin just below the outermost skin layer. The procedure uses a pen-like device that discharges a high-frequency electric current to small areas of the skin, creating small holes or micro-injuries in the skins layer. This process triggers a process of regeneration, encouraging cells known as fibroblasts to repair the skin and maintain firmness. The treatment helps eliminate excessive tissue that causes sagging skin, unwanted wrinkles, stretch marks, and even diminish scarring. The effects of the treatment should last as long as they would with invasive surgery, and the positive effects of treatment will be noticeable immediately after the first treatment, continuing over four weeks. The procedure is less invasive than other cosmetic procedures, and it may allow for quicker healing times and a faster return to usual activities. However, more research is still necessary to investigate this treatment, and the safety and effectiveness of the procedure are still being studied.
