La Roche-Posay ANTHELIOS PSF 50+ Fluide Extreme - 50mL w/Mexoryl XL

Ultraviolet radiation from UVA and UVB rays causes irreversible damage to the skin within minutes. UVB rays are energy-intensive and are the main cause of sunburns. The damaging effects of UVA rays are less visible. UVA rays can pass through glass and penetrate the skins deeper layers where they cause irreversible damage to the skins cells. Overexposure to the sun causes sunburn, solar intolerance, premature skin aging, age spots (hyper-pigmentation), and, most importantly, skin cancer. Solution for Sun Protection La Roche-Posay ANTHELIOS protects the skin from UVA rays (including short UVA rays), UVB rays (to help prevent sunburn), and infrared rays. Above all, ANTHELIOS provides long-term protection by filtering all the environments damaging rays: UVA, UVB, and IR. This is the result of a unique filtering system exclusive to ANTHELIOS ANTHELIOS sun protection products are: * non-comedogenic * hypoallergenic * water resistant * protective for reactive skin Sun radiation shielding products containing Mexoryl (chemical name Ecamsule) had higher UVA protection than sunscreens without Mexoryl. Mexoryl, available as SX (water soluble) and XL (lipid soluble), is very effective for two reasons: one, it is very stable [as a benzylidene camphor derivative], and two, because it undergoes photoisomerization, followed by photoexcitation, which means that it causes for UV light to be released as thermal energy rather than allowing for UV light to be absorbed into the skin and cause damage.
