Skin Compatibility Testing of Cosmetic Products Using Patch Tests for Dermatitis Diagnosis

What this Trial Is About

Researchers are studying the skin compatibility of cosmetic products by testing for potential irritants and allergic reactions. This trial focuses on adults with skin conditions who undergo patch testing to identify whether cosmetics cause skin irritation or allergies. The study is led by Insel Gruppe AG, University Hospital Bern, and aims to assess the safety of new or reformulated cosmetics for people with dermatitis. Participants will receive a patch test where a cosmetic product is applied to their back to observe skin reactions. This procedure helps to detect allergic or irritant responses. The study does not use a control or placebo group and does not involve masking or blinding. During the study, participants will be monitored for positive skin reactions to the patch test over a period of four weeks. Researchers will track the number of patients showing allergic or irritant responses. Participants must avoid certain medications and skin treatments before testing and will be followed to ensure accurate results and safety throughout the trial.
