The overall goal of this study is to develop regenerative cell therapy for use in female patients with aging skin. The primary objective of this proposal is to conduct a pilot study on the efficacy and safety of using PRP to treat this condition in females.

Recently, there has been interest in treatments which are orientated to more biologically regenerative therapies, with several studies demonstrating successful use for PRP in skin rejuvenation. Although PRP is widely used in clinical dermatology, experimental studies confirming the effects of PRP on aged fibroblasts are very limited.

PRP contains concentrated platelet cells derived from autologous whole blood that are believed to induce the synthesis of collagen and other matrix components by stimulating the activation of fibroblasts, thus rejuvenating the skin when injected into an area of collagen degeneration. In this proposal we will examine whether PRP therapy provides similar or better rejuvenating capacity in women compared to saline solution. The study will be a randomized, controlled trial comparing microneedling with PRP to microneedling with saline solution, in females aged 45 and over with skin aging of face. This study will also compare PRP to saline (given through injections via filler injection technique) in females with aging skin of the hands. Microneedling will not be performed on the hands.
