Summary

This clinical study employs a single-center, split-face, randomized, and on-site controlled design to compare two methods for inducing skin redness (50% Glycolic Acid application and tape stripping) on the face and forearm in a minimum of 40 healthy female subjects. The study involves instrumental measurements (erythema index and a\* value), photographic analysis, and expert clinical grading at multiple time points (baseline, 10min, 30min, 1h, 2h, and 4h after induction) to evaluate and compare the efficacy and response profiles of both irritation models.
