Chemical peeling with 35% glycolic acid for the treatment of disseminated facial verruca plana: a randomized, split-face, evaluator-blinded trial

Disseminated facial verruca plana is a chronic disorder that causes significant psychological distress. However, safe and effective treatment is lacking. This study aimed to explore the efficacy and safety of 35% glycolic acid for the treatment of disseminated facial verruca plana. A split-face clinical trial was conducted to explore the efficacy and safety of using chemical peeling with 35% glycolic acid for the treatment of disseminated facial verruca plana. One side of the face was applied with 35% GA once every fortnight for a total of three times. Adapalene gel was applied every night to the other side of the face as the control. The clearance rate of lesions was evaluated at different time points. Between June 2020 and December 2020, thirty patients with disseminated verruca plana who visited the Dermatology Hospital of Southern Medical University were enrolled. After three chemical peelings with 35% glycolic acid that was applied at 2-week intervals, 15(50%) patients achieved >70% lesion reduction. The same effective rate in the adapalene gel-treated side of the face was documented in eight patients. Subgroup analysis showed a higher clearance rate in patients with a shorter disease duration. Moreover, concurrent improvements in facial roughness were observed in the 35% glycolic acid-treated group. Adverse effects including mild erythema and desquamation were observed during chemical peeling with 35% glycolic acid. In conclusion, chemical peeling with 35% glycolic acid could be a safe and effective option for treating disseminated facial verruca plana, especially for those who desire skin improvement.
