Platelet-rich plasma as an adjuvant therapy to fractional ablative carbon dioxide lasers for cutaneous repair: a complementary treatment for atrophic acne scarring.

Abstract

Acne has a prevalence of over 90% among adolescents, and subsequently progresses to acne scarring in approximately 47% of cases. Due to the severe psychological and social ramifications acne scarring has on patients, there is a need for more effective treatments. Platelet-rich plasma (PRP), an autologous preparation enriched with growth factors, cytokines, and chemokines, has shown efficacy in promoting wound healing and tissue remodeling in dermatology. Recent evidence suggests that the efficacy of PRP may be enhanced when combined with laser therapy, which induces controlled tissue damage through photo-thermolysis thereby promoting tissue remodeling and epidermal regeneration. The microchannels created by laser treatments are thought to allow deeper penetration of PRP into the skin, potentially increasing its therapeutic effects. This review aims to analyze the combined use of PRP and laser therapy for treating acne scarring by examining randomized control trials from the past decade indexed on PubMed. Six studies met our inclusion criteria and were included in this review. The findings of this review support the hypothesis that combining PRP with laser therapy offers superior clinical results compared to monotherapy, providing a more effective approach to managing acne scarring.
