PRP for Acne Scars: Can Platelet-Rich Plasma Repair Scarred Skin? (2026 Evidence Guide)

Acne scars are among the most psychologically distressing skin concerns, affecting an estimated 95% of people who experience moderate to severe acne. Unlike active acne, which can be treated with medication, scarring represents permanent structural damage to the dermis that requires regenerative intervention to improve.

PRP therapy addresses acne scarring at its biological root. Rather than masking scars with fillers or ablating the surface with lasers, PRP delivers concentrated growth factors directly into scarred tissue to stimulate the collagen remodelling process that fills in depressed scars from within. When combined with microneedling, which creates controlled micro-injuries that amplify both collagen induction and PRP absorption, the results are progressive and natural.

At The London PRP Clinic, our GMC-registered doctors treat acne scarring with PRP facial protocols tailored to your specific scar types, depths, and skin tone. PRP facials start from £395 per session.

How PRP Repairs Acne Scars

Acne scars form when severe inflammation destroys collagen in the dermis. The body's repair process produces replacement tissue that lacks the organised collagen architecture of healthy skin, resulting in visible depressions, uneven texture, and discolouration.

PRP reverses this process by flooding the scarred tissue with concentrated growth factors that stimulate fibroblasts (the cells responsible for collagen production) to generate new, organised collagen. PDGF and TGF-beta promote fibroblast proliferation and collagen synthesis. VEGF improves blood supply to the scarred area, enhancing nutrient delivery. EGF stimulates keratinocyte proliferation, improving the epidermis above the scar.

When combined with microneedling, the treatment creates thousands of micro-channels through the scarred tissue that serve a dual purpose: triggering the wound-healing cascade that produces new collagen independently, and driving PRP growth factors deep into the dermis where they can reach the base of depressed scars.

This dual-action approach (microneedling collagen induction plus PRP growth factor stimulation) produces significantly greater scar improvement than either treatment alone. A 2024 meta-analysis of 13 RCTs involving 696 patients confirmed that combined microneedling therapy significantly improves skin parameters compared to single treatments.

Which Acne Scar Types Respond to PRP

Rolling scars are broad, shallow depressions with smooth, sloping edges that give the skin a wave-like appearance. These respond very well to PRP with microneedling because the collagen deficit is relatively shallow and diffuse, making it accessible to growth factor stimulation.

Boxcar scars are wider depressions with sharply defined vertical edges, similar to chickenpox scars. These respond well to PRP, particularly when multiple sessions build cumulative collagen remodelling that gradually raises the base of the depression.

Ice pick scars are narrow, deep, V-shaped punctures that extend into the deep dermis or subcutaneous fat. These are the most challenging scar type for any non-surgical treatment. PRP alone may produce limited improvement for deep ice pick scars. Combination approaches using subcision (breaking the fibrotic bands tethering the scar) followed by PRP often achieve better results.

Hypertrophic and keloid scars (raised scars) require different treatment approaches and are not primary indications for PRP.

Your doctor at The London PRP Clinic will assess your scar types using clinical examination and, where helpful, magnification, to design the most effective treatment strategy for your specific scarring pattern.

PRP vs Laser vs Filler for Acne Scars

Ablative laser (CO2, Erbium): £300 to £800 per session. Removes damaged surface skin to trigger deep collagen remodelling. Most aggressive non-surgical option. Significant downtime (7 to 14 days of healing). Risk of post-inflammatory hyperpigmentation, especially in Fitzpatrick skin types IV to VI (darker skin tones). Multiple sessions often needed.

Dermal filler: £250 to £500 per session. Physically fills individual scars with hyaluronic acid gel. Immediate visible improvement. Results last 6 to 12 months before the filler dissolves. Does not stimulate the skin's own repair. Not suitable for widespread scarring. Requires repeat treatments indefinitely.

PRP with microneedling: from £395 per session at The London PRP Clinic. Stimulates natural collagen remodelling using your own growth factors. Minimal downtime (24 to 48 hours of mild redness). Safe for all skin tones with no risk of hyperpigmentation. Progressive improvement over 3 to 6 months. Results are long-lasting because the new collagen is your own tissue.

PRP's safety advantage for darker skin tones is particularly significant. Laser-induced hyperpigmentation can persist for months and may be more distressing than the original scarring. PRP carries no such risk because it stimulates natural biological processes rather than thermally damaging tissue.
