Background: Eyelid dermatitis is a common, multifactorial, chronic, and/or relapsing condition with a considerable impact on life quality that represents a diagnostic and treatment challenge. Methods: We carried out a single-blind, controlled, randomized, parallel-group study to evaluate the efficacy of two dermo-cosmetics (cream for the eyelids and eye contour area and cleansing face cream) in which the key ingredient was witch hazel extract, compared to generic cream, in the treatment of patients affected by eyelid dermatitis. Enrolled subjects were treated and followed-up for 4 weeks; dermatological evaluation was objectively performed using the DLQI, OSDI, NRS–itch, and EDSI indicators. Results: The products tested proved to be more effective than the placebo in ameliorating the dermatitis in the treated patients, based on all considered dermatological scores. In the treatment arm, we observed a reduction in both DLQI score and in the indicators related to the extension of dermatitis, greater than that observed in the control arm. Conclusions: This comparative study demonstrates the role of dermo-cosmetic products tested not only as a support treatment, but also as a first-choice clinical approach.
