Comparative study of dermaroller therapy versus trichloroacetic acid CROSS for the treatment of atrophic acne scars

ABSTRACT

To compare the efficacy and safety of dermaroller treatment with that of TCA CROSS in acne scars. We selected thirty patients of atrophic acne scars for the study. Group I patients underwent four sessions of dermaroller therapy four weeks apart. Group II were treated with four sessions of TCA CROSS technique four weeks apart. After four sessions of dermaroller and TCA CROSS each, marked improvement was seen in 40% patients in the dermaroller group and in 60% patients in the CROSS group. Moderate improvement was seen in 40% patients in dermaroller group and in 26.6% patients in the CROSS group and mild improvement was seen in 20% patients in dermaroller group and 13.3% patients in the CROSS group. Side effects were mild and infrequent in both groups. Both treatments are equally effective and safe for the treatment of acne scars
