A Split Face Study to Compare the Efficacy of Platelet Rich Plasma Versus Normal Saline Injections in Acne Scars and to Assess the Utility of Ultrabiomicroscopic Sonography in Evaluation of Treatment Response

This study found that platelet-rich plasma injections led to significant improvements in atrophic acne scars on the treated side of participants' faces compared to the untreated side.

This study found that combining platelet-rich plasma with microneedling or fractional CO2 laser therapy was more effective in treating postacne atrophic scars than using these therapies alone, also boosting patient satisfaction.

This study reports that platelet-rich plasma therapy significantly improved hair regrowth in alopecia areata and reduced the severity of atrophic acne scars over six months, with generally mild side effects.

This study found that adding platelet-rich plasma to microneedling improved outcomes for atrophic acne scars more than microneedling alone, according to both quantitative and qualitative assessments.

In this study, 46 patients aged 18-25 with atrophic acne scars underwent microneedling combined with autologous platelet-rich plasma therapy, resulting in significant improvement in 86.9% of cases without serious complications, suggesting this combination is effective for enhancing the appearance of acne scars.
