Back when the very first sunscreen was introduced in 1928, it was believed that the short-term harmful effects of ultraviolet (UV) radiation exposure, specifically sunburn, were all we had to fear from the sun. In the succeeding decades, however, it has become clear that sunburn is only the beginning of the pathologic effects produced by solar exposure.
Recent years have brought a much fuller understanding of the effects of photoexposure, their causes, and ways to protect against them.
On July 21, La Roche-Posay, a division of L'Oreal, received approval from the Food and Drug Administrative (FDA) to market a broad-spectrum sunscreen formula that contains Mexoryl SX (ecamsule) plus L'Oreal's patented association with avobenzone (Parsol 1789) and octocrylene.
Mexoryl SX was first patented in Europe by L'Oreal in 1982 and has been available in sunscreens and moisturizer products sold outside of the United States. Mexoryl SX is a unique organic sun filter because it is highly protostable and provides potent protection against short-wavelength UVA rays (320 nm to 340 nm), thereby filling a gap left by existing UVA sunscreens.
Mexoryl SX: Finally Available in the US
The first sun filter approved by the FDA in 18 years. A breakthrough technology in sun protection. Mexoryl SX is contained in Anthelios SX and Anthelios 40 sunscreens.
What is MEXORYL SX?
MEXORYL SX 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. 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.
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 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 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.
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.
2009 Innovation: CELL-OX Shield
With the launch of Anthelios 60, La Roche-Posay introduces CELL-OX Shield the newest innovation in the Anthelios francise for UVA and UVB protection down to the cellular level.
What is CELL-OX SHIELD
CELL-OX SHIELD is the patent pending dual protection technology that is available in Anthelios 60 and Anthelios 45 sunscreens.
How does CELL-OX SHIELD work?
CELL-OX SHIELD Provides 2 lines of defense against cell damage:
- First line of defense: outstanding UV protection on the skin’s surface
A patent pending synergistic filtering system with a performance booster to deliver longer-lasting2 photostable and broad-spectrum protection with enhanced efficacy against UVA and UVB rays
- Second line of defense: exclusive antioxidant protection
A powerful patent-pending new antioxidant combination, including Senna Alata to provide added skin protection against cell damage
Why is CELL-OX SHIELD so unique?
In addition to the patent pending UV filter system with a performance booster that pushes photostabilization, the antioxidant combination is also unique to CELL-OX SHIELD (patent-pending). One key anti-oxidant in our formulation is Senna Alata, a tropical leaf extract, which is also used in the international Anthelios line of sunscreens.
CELL-OX Shield is available in Anthelios 60 Ultra Light Sunscreen Fluid, Anthelios 60 Melt-in Sunscreen Lotion for the Face and Anthelios 60 Melt-In Sunscreen Milk for Face and Body. In May of 2010, LaRoche-Posay announced the new launch of Anthelios 45 Ultra Light Sunscreen Fluid for the Face and Anthelios 45 Ultra Light Sunscreen Fluid for the Body with CELLOX-OX Shield.
