Clinical and Environmental Factors Impact Absorption of Common Sunscreen Ingredient
American Association of Pharmaceutical Scientists (AAPS)With the growing awareness of ultraviolet (UV) exposure resulting in an increased risk of photoaging and skin cancers, consumers are using higher sun protection factor (SPF) sunscreens with frequent reapplication. New research, Evaluation of Reapplication and Controlled Heat Exposure on Oxybenzone Permeation from Commercial Sunscreen Using Excised Human Abdominal Skin, presented today at the 2018 American Association of Pharmaceutical Scientists (AAPS) PharmSci 360 Meeting demonstrates that heat and reapplication influences different sunscreen products containing the same amount of a key ingredient, oxybenzone, potentially affecting safety and toxicity of the UV filters included in sunscreens.
