Introduction Acne scarring is a common complication of acne, and no appropriate and effective single treatment modality has been developed yet. A new technique of focal application of high strength trichloroacetic acid (TCA) (65-100%) has been suggested. The aim of the study was to evaluate the efficacy and safety of 50% TCA in three different types of atrophic acne scars using the chemical reconstruction of skin scars technique in three sessions, each at an interval of 1 month. Materials and methods Thirty adults with a clinical diagnosis of atrophic acne scars were selected. Results Statistically significant difference was found in the total Goodman score between the atrophic acne scars before and after treatment (P < 0.0001), especially between the icepick and boxcar scars before and after treatment (P < 0.05). In addition, statistically significant difference was observed in the percentage of improvement between the three types of atrophic acne scars (P < 0.05). The best improved were the icepick type followed by the boxcar scars and then the rolling scars. Conclusion Chemical reconstruction of skin scars technique using 50% TCA is nonsurgical and safe in the treatment of atrophic acne scars, especially the icepick type followed by the boxcar scars, with minimal side effects and a short downtime.
