Repair and rejuvenation of tissues using platelet-rich plasma

Abstract

This application relates to cosmetic methods for improving skin conditions. The methods generally include the administration of platelet-rich plasma and cultured autologous cells to a subject after a micro-needling procedure has been performed. The platelet-rich plasma and autologous cells can be topically applied to the skin surface or injected into the dermis or subcutaneous tissue. The methods may be used to improve conditions such as acne scars, traumatic scars, hyperpigmentation, fine lines, wrinkles, stretch marks, and hair loss.

Description

field of invention [0001] The present application relates to methods for administering a platelet-rich plasma (PRP) composition to a subject. Specifically, the method may involve topically applying the PRP composition to the skin surface after microneedling, or injecting the PRP composition into subcutaneous or skin tissue. The PRP composition will typically include cultured autologous cells, such as cultured autologous fibroblasts. Conditions such as acne scars, traumatic scars, hyperpigmentation, fine lines, wrinkles, stretch marks, and hair loss can be treated using the composition. Background of the invention [0002] The injection of synthetic materials into the body, and especially into the face, to achieve cosmetic results began at the end of the nineteenth century. For example, paraffin injections to correct facial contour defects were accepted for a brief period in the years leading up to World War I. However, complications and poor long-term outcomes led to the ...
