THE FIRST SUNSCREEN APPROVED BY THE FDA IN 18 YEARS! A light, non-greasy, fragrance free formula.
Allergy tested, PABA-free, suitable for sensitive skin, offers 24-hour hydration, and the most complete broad spectrum protection. MEXORYL™ SX is the most effective organic UV filter that protects against UVA rays (maximum absorption at 344nm) with high photostability, a key factor in sunscreen protection efficacy. This high photostability means the sunscreen will maintain a higher UVA protective ability longer and not degrade as quickly as other UVA filters when exposed to the sun.
Why is MEXORYL™ SX unique?
When UVA and UVB inorganic protective filters were first introduced using cosmetically acceptable concentrations, 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, now available in the US, is photostable on its own and is the most effective 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 a complete broad spectrum UV protection, with the highest level of protection across the UVA spectrum––particularly short UVA rays in the range of UVA 320-340nm.
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.
