Abstract:
Post-acne atrophic scars (PAS) are a common complication of acne, and their treatment can be limited in people of color due to dyspigmentation and scarring risks. This split-face study compared the efficacy of microneedling with topical insulin (TI) on one side of the face with microneedling with platelet-rich plasma (PRP) on the other side for the treatment of PAS. The study included 50 participants with Fitzpatrick skin types III to VI who had never been treated for PAS. Both sides of the face showed significant improvement, with the left side being treated with TI showing a 52% improvement and the right side being treated with PRP showing a 28% improvement. The treatment was well-tolerated, with no significant adverse effects, and no changes in blood glucose levels were observed. The researchers suggest that combining TI or PRP with microneedling can improve PAS treatment, with TI being a superior option due to its ease of use, low cost, and noninvasive nature.
