NCT05013645

Brief Summary

Double-blind placebo-controlled clinical trial to evaluate the effectiveness of a sterilized probiotic on skin health and hydration in adults with dry skin. The goal of the study is to determine if the addition of a skin-conditioning probiotic to a standard gel product will moisturize the skin, support a healthy skin microbiome, and be readily tolerated by adults with dry skin.
