Allergic contact dermatitis to phloretin, a luxury cosmetic ingredient, involving a woman with atopic dermatitis.

This article discusses a case report of a 35-year-old woman with a history of atopic dermatitis and asthma who experienced outbreaks of facial and neck eczematous reactions. The patient had positive reactions to a luxury antioxidant serum product containing phloretin, a natural dihydrochalcone found in apple trees and other plants. After discontinuing the use of the cosmetic product, it took several weeks for the eczematous lesions to heal. The article highlights the importance of recognizing the potential for sensitization and allergic contact dermatitis caused by substances of plant origin in cosmetics, and suggests that simpler formulas with fewer ingredients may be more suitable for vulnerable patients with disrupted barrier skin function.
