Efficacy and tolerability of 1.6% phenol-croton peeling versus topical 5% imiquimod in the treatment of actinic cheilitis: a randomized clinical trial.

Background: Trials evaluating the effectiveness of topical treatments for actinic cheilitis (AC) are scarce. Despite no comparative data, phenol-croton peeling has been reported as effective in treating this condition.

Methods: An open, randomized trial was conducted to compare the effectiveness and tolerability of 1.
