Abstract
Platelet-rich plasma (PRP) is an autogenous compound acquired through the collection and processing of the patient's own blood. The procedure allows the acquisition of high concentration of platelets from small volumes of processed fluids. Platelets, because they have growth factors and cellular proteins, stimulate tissue repair, formation of new blood vessels, increasing vascularization, activating the production of collagen and elastin, proteins that are indispensable for a structured and healthy skin. Thus, this narrative literature review proposes to expose the use of PRP in collagen biostimulation and facial rejuvenation. In this research, the main functions of the growth factors present in PRP were discussed, the expected indications for each component obtained after plasma processing and the main forms of application to treat skin aging.
