Dometrizole trisiloxane (Mexoryl XL®) is a lipophilic benzotriazole derivative used in sunscreen products to absorb ultraviolet (UV). It is a broadspectrum UVB/UVA filter with two peaks of absorption: one at 303 nm and the other one at 344 nm. Sunscreens containing dometrizole trisiloxane (Mexoryl XL®) are important in impeding UVA light, potentially reducing many of the characteristics of skin aging and preventing biochemical changes that can lead to nonmelanoma carcinoma. It has not yet been approved in the US, but has been available worldwide for many years in different sunscreens made by L'Oreal.

Sample Use Guides

In Vivo Use Guide

Apply the sunscreen product just before exposure. Re-apply frequently and generously to maintain protection, especially after perspiring or towelling.

Route of Administration: Topical

In Vitro Use Guide

Suncreen A tested (UVB: Octocrylene; UVA: Mexoryl SX, Mexoryl XL, Parsol 1789; TiO2) provided protection against the development of UV radiation-induced skin lesions in patients with photosensitive lupus erythematosus. This protective capacity was corroborated by studies in which strong ICAM-1 mRNA expression was found in unprotected test areas, but not in sunscreen A pretreated sites.
