PRP injected into specific areas of the face help rejuvenate the skin from within. Rejuvenation occurs when platelets release their growth factors and signal the skin, the subcutaneous connective tissue, and the tissue layers under the skin to switch into repair mode. PRP triggers new capillary formation (Angiogenesis) and causes fat cells under the skin to get plumper (fat hypertrophy). PRP also results in increased skin cell turnover as well as organized new collagen deposition.
