Stretch Marks and Body Scars: Can PRP Really Fade Them?
Stretch marks (striae) and surgical scars are notoriously difficult to treat. Creams and oils sit on the surface and do almost nothing for the deep structural tears in the dermis. Lasers can be effective but come with significant downtime and risk of pigmentation, especially on darker skin.
PRP therapy is changing the conversation around body scarring. By delivering high concentrations of growth factors directly into the scar tissue, we can remodel the skin from within.
Why Stretch Marks Happen
Stretch marks are essentially scars. When the skin is stretched too quickly (puberty, pregnancy, weight gain), the collagen and elastin fibres in the dermis snap. The skin heals, but the new tissue is thinner and differently textured than the surrounding skin.
Red marks (Striae Rubra): New, inflamed scars with blood vessels.
White marks (Striae Alba): Older, faded scars that are harder to treat.
How PRP Remodels Scars
PRP is often combined with Microneedling for body scars.
Mechanical Breakdown: The needles physically break up the tough, fibrous scar tissue.
Biological Repair: The PRP is soaked into the deep channels. The growth factors (PDGF, TGF-beta) tell the body to produce new, organised collagen instead of scar tissue.
Melanocyte Regulation: It helps normalise pigment, making white scars blend better with the surrounding skin.

What Can Be Treated?
Post-Pregnancy Stretch Marks: Abdomen, hips, and breasts.
Surgical Scars: C-section scars, tummy tuck scars, or orthopaedic surgery scars.
Growth Spurts: Marks on the thighs or back.
Realistic Expectations
PRP cannot erase a scar completely—nothing can. But it can significantly improve:
Texture: Making raised or indented scars flush with the skin.
Colour: Fading redness or blending white marks.
Width: Making wide stretch marks appear thinner.
Results are cumulative. You will likely need 3 to 6 sessions, spaced 4-6 weeks apart, to see a major transformation.
