Drometrizole trisiloxane is a lipophilic benzotriazole derivative marketed as Mexoryl XL by L'Oréal and is used in sunscreens as a (UV) filtering agent that provide a high sun protection factor (SPF) for daily photoprotection of skin against UV damage and delay the signs of aging. Drometrizole trisiloxane is a broad-spectrum UV absorber with two absorption peaks, one at 303 nm (UVB) and one at 344 nm (UVA). Sunscreens with drometrizole trisiloxane are approved within the EU, Australia and other contries but not in the United States.
