PRP Injections

RENATA Facial Cosmetic Surgery in DUMBO, Brooklyn offers PRP (platelet-rich plasma) injections as an all-natural, autologous treatment for facial rejuvenation and scalp hair thinning. A small blood sample is drawn from the patient, centrifuged to concentrate the platelet and growth factor-rich plasma, and then injected or applied to the face, neck, or scalp. PRP stimulates collagen production, accelerates skin renewal, and improves fine lines, acne scars, and skin texture. A course of three to six monthly sessions is recommended. PRP can be combined with microneedling or laser resurfacing for enhanced results.

Platelet-rich plasma injections at RENATA Facial Cosmetic Surgery represent a biologically driven approach to facial and scalp rejuvenation, leveraging the patient's own concentrated growth factors to stimulate tissue repair and regeneration without synthetic materials. The procedure begins with a standard venous blood draw, which is processed in a specialised centrifuge that separates plasma, platelets, red blood cells, and white blood cells by their differing densities. The resulting platelet-rich plasma contains a concentration of platelets approximately three to five times above the physiological baseline of whole blood. Platelets store an array of bioactive growth factors in their alpha granules, including platelet-derived growth factor (PDGF), transforming growth factor beta (TGF-β), vascular endothelial growth factor (VEGF), epidermal growth factor (EGF), and insulin-like growth factor (IGF-1). When PRP is introduced into the tissue through injection, these growth factors bind to surface receptors on local fibroblasts, keratinocytes, and stem cells, triggering downstream signalling cascades that upregulate collagen synthesis, accelerate epidermal cell turnover, promote new capillary formation, and recruit progenitor cells to the treatment site. At RENATA, PRP injections are used across three primary applications. For facial rejuvenation, PRP is micro-injected into the superficial dermis across the face and neck, addressing fine lines, skin laxity, dullness, and acne scarring by building new collagen and improving skin architecture from within. For acne scar improvement and skin texture concerns, PRP is often delivered in combination with the clinic's microneedling protocol — the micro-channels created by the needling device allow simultaneous topical PRP penetration deep into the dermis, amplifying the growth factor stimulus. For scalp applications, PRP injections into the subdermal scalp layer can support hair follicle activity in patients experiencing early androgenetic alopecia or diffuse hair thinning, with the goal of prolonging the anagen (active growth) phase and increasing hair density over a course of treatments. A course of three to six monthly sessions is the standard protocol at RENATA, with maintenance injections recommended every six to twelve months depending on the application. Results build progressively over four to eight weeks following each session as the growth factor response stimulates new tissue formation.
