How Does PRP Work for Acne Scars
Platelet-rich plasma, or PRP, is a treatment made from your own blood that helps heal acne scars by boosting your skin’s natural repair process. It works because platelets in your blood release special proteins called growth factors that tell your skin cells to make more collagen and regenerate tissue[1][2][3].
Doctors start by drawing a small amount of blood from your arm, similar to a routine blood test. They put it in a machine called a centrifuge that spins fast to separate the blood into layers. The top layer is the PRP, which has a high concentration of platelets packed with those healing growth factors[1][3][6].
For acne scars, which are often pits or depressions from lost skin tissue like icepick, boxcar, or rolling scars, PRP is usually combined with microneedling. Microneedling uses tiny needles to poke small holes in the skin, creating micro-channels that trigger healing and let the PRP soak in deeper[1][3][4].
Once applied or injected through those channels, the growth factors in PRP kick into action. They speed up collagen production, which fills in the scarred areas over time. This also reduces inflammation and redness faster than microneedling alone, leading to smoother skin texture and better tone[1][2][3].
Studies show this combo works better for tough atrophic acne scars than microneedling by itself, with patients seeing noticeable improvements after one or two sessions. Full results build up over a few months as new collagen forms, and most people need three sessions spaced weeks apart[1][3].
PRP is natural since it comes from your body, so it has low risk of allergic reactions. It can be used alone by injection or with other tools like microneedling for stronger effects on scars[2][5][6].
