Simply put, XL-PROTECT technology is La Roche-Posay’s most complete sun protection to date.

In order to block an impressive spectrum of the sun’s rays - from UVB all the way to UVA – it smartly combines filters offering very high protection SPF50. 

But XL-PROTECT goes beyond classic broad-spectrum UVA and UVB protection. It also integrates a powerful anti-oxidant complex to defend against oxidative stress induced by other key environmental aggressors, such as long UVA, infrared and pollution.

What does our filtering system complex bring more?

For decades, sun filters have defended skin against two main classes of solar radiation:                                     
UVB (B for surface “Burn”) and UVA (A for in-depth “Aging”). 

But most UV rays reaching the earth’s surface actually belong to a subgroup called long UVA, which many filters don’t protect against. These rays penetrate deeper within skin and generate free radicals that are responsible for cells oxidation and skin damage (everything from pigment spots to wrinkles and skin cancer).   

The superior blend of filters to defend skin

The power of effective sun protection resides mainly in its UV filter composition to cover the largest possible spectrum. The key Anthelios products use a unique combination of organic UV filters including Mexoryl XL and a mineral filter Titanium Dioxide, to cover a broader spectrum of UV radiation, with the aim of leaving no “gaps” in the coverage. The filters fit together like a jigsaw puzzle to offer the most optimal protection, with a synergistic effect offering up to twice the UVA and UVB protection than the filters taken individually. And all of this in a formula that stays photostable under the sun.

An anti-oxidant complex to tackle oxidative stress induced by pollution and infrared

Beyond UV radiation, two of the most prominent environmental aggressors responsible for skin oxidative stress are pollution and infrared. Both fuel invisible damages in the skin, like the oxidative stress that acts as a tag team with UV causing dramatic aging effects.

To help neutralize the effects of these two skin aggressors at every level of skin, Anthelios products with XL-PROTECT integrates a powerful antioxidant blend, including:

  • La Roche-Posay Thermal Spring Water: a unique mineral composition and selenium concentration able to boost skin’s own antioxidant enzymes for added protection against the effects of UVA, UVB and pollution.[1]
  • Vitamin E: also known as tocopherol, this is a lipid-soluble molecule present in our own cell membranes to neutralize oxidative stress. It also helps to reduce the damaging effects of UVA, UVB and pollution[2].
  • Baicalin: a naturally-occurring polyphenol used in traditional Chinese medicine for centuries for its soothing and antioxidant properties. It has been shown to offer extra protection against both UVA[3] and long-UVA[4].

XL-PROTECT = anti UVB + UVA + Oxidative Stress [Infrared + Pollution]

3 reasons to prefer XL-protect

By assuring a global protection against both UV and urban aggressors, XL-Protect offers concrete on-skin benefits:

  • To reduce cell damage: cells are protected against the risk of developing skin cancer.
  • To reduce oxidative stress: the invisible skin damage and aging effects due to UV and urban aggressors are diminished.
  • To reduce photoaging: in other words, less of the characteristic signs of “sun damage” such as wrinkles, rough texture and hyperpigmentation (dark spots).
