Anthelios with Mexoryl SX & XL - a True Breakthrough in Sun Care

The Longevity Boutique is proud to present a wide range of the breakthrough sun protection products from the Anthelios line, manufactured by the world-famous french Labaratoire la Roche Posay.  Most suntan lotions on the market today are good at screening out the sun's UVB rays -- the ones that cause sunburn and skin cancers -- but most people don't realize their sunscreens don't offer much protection against UVA rays, the ones that put wrinkles in your skin.  Mexoryl has been marketed as a breakthrough ingredient, providing protection that is said to be far more comprehensive than commonly used UVA filters such as Oxybenzone, Titanium Dioxide or Parsol 1789.   The ingredient has been licensed for use in Europe since 1993, where it is generically known as ecamsule, and is incorporated into a number of leading sunscreen products.  UVB rays commonly cause the skin to go red and burn. However, UVA rays penetrate the lower dermal layer of the skin, leading to wrinkling and a greater risk of developing skin cancer.   Because of this evidence UVA protection has become increasingly sophisticated in recent years, in an attempt to provide better sun protection.

Ecamsule (trade name  Mexoryl® SX,  Terephthalylidene Dicamphor Sulfonic Acid) is a chemical which filters out UVA rays. It is a benzylidene camphor derivative, many of which are known for their excellent photostability.   Although there are a few different UV absorbers with the trade name Mexoryl, only two of them are widely used where approved. Mexoryl SX (water soluble) and Mexoryl XL (Drometrizole Trisiloxane, oil soluble). Together they show a synergistic effect in protection

Exposed to UV, ecamsule undergoes reversible photoisomerization, followed by photoexcitation. The absorbed UV is then released as thermal energy, without penetrating the skin.

In studies done in mice it reduces the formation of UV induced pyrimidine dimers and delays the onset of skin cancer. In vitro ecamsule effectively protects against the harmful effects of UV.   Ecamsule has little percutaneous absorption and little systemic effects, therefore it is considered relatively safe.       It does not increase the probability of promoting skin cancer. Studies done in vitro show that it is not photomutagenic.
