Mexoryl SX (Ecamsule) is the most effective FDA-approved organic filter designed to protect against short UVA rays (maximum absorption at 344nm) with high photostability, a key factor in sunscreen protection efficacy. Found in La Roche Posay, Anthelios line of sunscreens, this high photostability means the sunscreen will maintain a higher UVA protective ability longer and not degrade as quickly as other FDA approved UVA filters when exposed to the sun. protection sign on sunscreens.

What is photostability?

Photostability means the ability to stabilize under sunlight. The process of photostability is a key factor in sunscreen protection efficacy. High photostability means the sunscreen will maintain a higher UVA protective barrier.

Why is Mexoryl SX unique?

When UVA and UVB protective sun filters were first introduced, they provided minimal protection against UVA rays. Though the UVA ray filter molecule Avobenzone (Parsol 1789) was approved for drug store and apothecary use in 1992, it was discovered that when used by itself, Avobenzone (Parsol 1789) degrades when exposed to the sun, thereby reducing its UVA protection efficacy.

Mexoryl SX sunscreens, is photostable on its own and is the most effective FDA-approved organic filter designed to protect against short UVA rays. Formulations containing Mexoryl SX and L’Oreal’s patented photostable association of Octocrylene and Avobenzone provide complete broad spectrum UV protection, with a high level of protection across the UVA spectrum - particularly short UVA rays in the range of UVA 320-340nm. Anthelios Lait SPF 45 contains the Mexoryl SX technology.

How does Mexoryl SX work?

Mexoryl SX protects the skin by absorbing the energy of the sun’s short UVA rays. Mexoryl SX acts as a normal filter, but becomes highly energized by absorbing the energy of a UV photon. Mexoryl SX protects against UVA photons penetrating your skin, deactivates and releases the absorbed energy to the environment as harmless energy, then repeats the process over and over.

Mexoryl SX offers the following advantages:
· Highly photostable
· Most effective FDA approved sun filter to protect against UVA rays
· Allows for the most complete UV protection when combined with other effective sun filtering agents
· Is tolerated very well by most individuals

Products containing Mexoryl SX such as Anthelios and Ombrelle sunscreens may be purchased from quality pharmacies in Canada and worldwide.
