    Abstract:
    Acne scars represent a therapeutic dilemma. This study aimed to evaluate the efficacy of combined subcision, autologous platelet-rich plasma (PRP), and chemical reconstruction of skin scars (CROSS) technique in the treatment of acne scars. In 20 patients with atrophic acne scars, one facial side was treated with subcision plus PRP, and the other was treated with the same combination plus CROSS technique (trichloroacetic acid 50%) for 3 sessions at 3-week intervals. Clinical evaluation, digital photography, quantitative global scarring grading system, and Lipper and Perez score were done at baseline, every session, and 1 month after the last session. Participants assessed their improvement at the end of the follow-up period using a scale (0 to 10). There was a significant reduction in quantitative global scarring grading system (P < .001) and Lipper and Perez score (P < .001) after treatment compared with baseline in both sides. No significant difference was found when the two treated sides were compared after treatment by both scores. Patients' satisfaction was excellent (12 patients [60%]) and good (eight patients [40%]) with no significant difference between both sides. In conclusion, combined subcision and PRP is recommended for acne scars. Adding CROSS technique (trichloroacetic acid 50%) did not further ameliorate the condition.
