Abstract
Background: Facial scars resulting from acne are either hypertrophic or atrophic depending upon whether they are elevated or depressed in relation to the skin surface. The atrophic facial scars are divided into different morphological types depending on the shape and depth of the scars. Fractional CO2 laser and platelet-rich plasma (PRP) treatments have been used in the treatment of acne scars. However, an objective method of assessment has been lacking. Objective: To evaluate the efficacy of fractional CO2 laser treatment alone versus PRP and fractional CO2 objectively in post acne scars. Patients and methods: Thirty patients with atrophic acne scar lesions were included in this study. Patients were randomized to receive fractional CO2 laser therapy to one side of the face while the other side of the face was treated with fractional CO2 laser followed by intradermal PRP injection. Follow up using the skin analysis camera system and photography was done for three months. Results: A dramatic improvement was observed in the scar depth on both sides of the face. However, the combined fractional CO2 laser and PRP showed more significant improvement. Improvements in the scar appearance and skin texture were reported by the patients. Although 70% of our patients were of a dark skin type, no hyperpigmentation was reported. Conclusion: The combined use of fractional CO2 laser and PRP achieved better results. It reduced the downtime of the fractional CO2 laser. The use of the skin analysis camera provided an objective assessment of the results.
