Evaluation of autologous platelet-rich plasma plus ablative carbon dioxide fractional laser in the treatment of acne scars

Introduction: Acne scar is a common distressing complication of acne vulgaris. CO2 laser resurfacing proved effective for the treatment of this problem, but the associated complications may limit its use. Platelet-rich plasma (PRP) may increase the chance of favorable outcome. Aim of the work: To evaluate the synergistic effects of autologous PRP with fractional CO2 laser resurfacing in the treatment of acne scars among Egyptian patients. Patients and method: This study included 30 patients suffering from post-acne scars. CO2 laser treatment was applied to both sides of the face followed by PRP injection for the right side. Evaluation was carried out through operating physicians, two blinded physicians as well as through patient's satisfaction. Result: The right side of the face (PRP-treated side) achieved excellent improvement in 13.3% of the patients, while there was no excellent improvement on the left side. Conclusion: Combination of fractional CO2 laser resurfacing and intradermal PRP was superior to CO2 laser alone for acne scar treatment.
