PRP (Platelet-Rich Plasma) Therapy

PRP therapy harnesses the patient's own growth factors to stimulate tissue regeneration, collagen production, and skin renewal. At Edwin Lim Medical Aesthetic Clinic, PRP is used for facial rejuvenation, in combination with microneedling, and for hair loss treatment.

Platelet-rich plasma (PRP) therapy is an autologous biological treatment — meaning it uses the patient's own blood — making it an appealing option for those who prefer to avoid synthetic injectables. The procedure begins with a small blood draw (typically 15–20 ml), which is placed in a centrifuge and spun to separate the plasma fraction rich in platelets and growth factors from the red blood cells. The concentrated PRP is then activated and applied to the treatment area. In facial rejuvenation, PRP can be applied topically during a microneedling session (allowing deep dermal penetration through the micro-channels), or injected intradermally at targeted areas to stimulate fibroblast activity, collagen synthesis, and angiogenesis. Growth factors in PRP include platelet-derived growth factor (PDGF), transforming growth factor-beta (TGF-β), vascular endothelial growth factor (VEGF), and epidermal growth factor (EGF) — collectively responsible for the tissue repair and regenerative effects. Results are gradual, with improvements in skin firmness, luminosity, and hydration evident over six to eight weeks. PRP for hair loss (alopecia areata or androgenetic alopecia) involves scalp injections that stimulate dormant follicles and extend the anagen (growth) phase. A course of three sessions one month apart is the standard protocol, with an annual maintenance session. Patients with early-to-moderate hair thinning see the most predictable results. Because PRP is derived from the patient's own blood, the risk of allergic reaction is negligible. Minor bruising at injection sites resolves within a few days. Results build progressively over two to three months as the biological remodelling process runs its course.
