The effect of TCA chemical peel on acne scars

Background: Trichloroacetic acid (TCA) chemical peel has been used for variable skin lesions. However, the effect of TCA chemical peel on acne scars has not been studied. Objective: The object of this study is to evaluate the effect of TCA chemical peel on atrophic acne scars. Method: Twenty-three patients with atrophic acne scars, who were treated with TCA chemical peel were included. The patients were interviewed for evaluation of the therapeutic efficacy of TCA chemical peel regarding the number of treatment and satisfaction rates. Results: Those who received treatment for more than 6 times with good or excellent results were 13 out of 15 patients, whereas, those who received treatment for 4 times with good or excellent results were 4 out of 7 patients. Thus, chemical peel on acne scars showed that the more often the treatment was carried out, the better the therapeutic effect. There was no significant complication. Conclusion: TCA chemical peel is safe and effective for the treatment of atrophic acne scars.
