Microneedling, also known as collagen induction therapy, is a wonderful treatment option for treating acne scars. The SkinPen is FDA cleared for the improvement of acne scars by stimulating collagen and elastin. For best results, a series of treatments spaced one month apart is recommended. Microneedling causes tiny micro-injuries in the skin that creates wound healing and the release of growth factors without the use of heat. Platelet-rich plasma (PRP) can also be incorporated into the treatment for added collagen stimulation.
