Treatment of acne scars with PRP and laser therapy: an up-to-date appraisal.

Clinically significant scarring is a common complication of acne vulgaris. Recent treatments have included the use of platelet-rich plasma (PRP), especially in combination with laser therapy. Here, we offer backgrounds on PRP and laser therapy and review combination treatment for acne scars. It is important to note that current data are limited to small studies and that there is no standard protocol for PRP administration. Larger studies are needed to better evaluate combination treatment and determine the best modality.
