Microneedling with PRP

Collagen-induction microneedling using a medical-grade pen device with adjustable needle depth to treat acne scars, enlarged pores, fine lines, uneven texture, and early skin laxity. PRP (platelet-rich plasma) derived from the patient's own blood is applied to the treated area to enhance healing and stimulate growth factor activity. A series of three sessions spaced four to six weeks apart is recommended. Downtime is forty-eight to seventy-two hours of redness.

Microneedling with platelet-rich plasma (PRP) at Complexions Medical Spa Boston combines two complementary mechanisms of collagen stimulation to achieve skin renewal beyond what either modality achieves independently. Medical-grade microneedling uses a motorised pen device with a sterile disposable needle cartridge (typically twelve to thirty-six micro-needles in a circular array) to create thousands of micro-channels in the skin per pass, penetrating at programmable depths from 0.25 mm to 2.5 mm. These controlled micro-injuries trigger the skin's natural wound-healing cascade: the inflammatory phase brings growth factors and cytokines to the treated area, followed by a proliferative phase during which fibroblasts produce new collagen, elastin, and hyaluronic acid in the treated zone. The net effect is a progressive improvement in skin density, texture, and surface irregularities over the weeks following each session. PRP — platelet-rich plasma prepared from a small volume of the patient's own blood by centrifugation to concentrate the platelet fraction — is applied topically to the skin surface immediately after microneedling while the micro-channels are open. The open channels serve as conduits for transdermal delivery of the PRP's concentrated growth factors — including platelet-derived growth factor (PDGF), transforming growth factor-beta (TGF-β), vascular endothelial growth factor (VEGF), and epidermal growth factor (EGF) — directly into the dermis, bypassing the barrier that limits topical penetration under normal conditions. This targeted delivery of autologous growth factors amplifies the fibroblast response initiated by the micro-injury, producing more robust collagen remodelling and faster healing compared to microneedling alone. The treatment is particularly effective for atrophic acne scarring (rolling, boxcar, and shallow ice pick subtypes), enlarged pores, fine lines, post-inflammatory erythema, and generalised skin quality improvement. The full face is treated in a single session lasting approximately forty-five to sixty minutes including numbing preparation. Downtime consists of redness and mild swelling resembling a moderate sunburn, typically resolving within forty-eight to seventy-two hours. A standard course of three sessions spaced four to six weeks apart is the recommended protocol, with results continuing to improve through three to six months as new collagen matures.
