Does New Anthelios 40 Sunscreen Deliver?

Anthelios 40 is a new broad spectrum UVA and UVB blocking sunscreen by La Roche Posay just approved by the FDA. But is it really the best sunscreen that you can buy?

Formulated with Mexoryl SX (ecamsule), Anthelios 40 is a definite improvment over sunscreens currently available in the US. However, what’s just as important as what Anthelios 40 does contain is what it doesn’t contain. Anthelios 40 lacks Mexoryl XL, another UVA blocker found in Anthelios sunscreens from Canada and Europe. A sun filtering molecule related to Mexoryl SX, Mexoryl XL affords protection against UVB rays as well as longer UVA rays. When Mexoryl XL and Mexoryl SX are combined together, the effect is synergistic giving far better protection than when either ingredient is used alone. This means protection not only against sunburns from UVB rays, but also against the long term skin damage that is associated with UVA rays.

Difference between Mexoryl XL and Mexoryl SX

Mexoryl XL is a lipid soluble molecule making it ideal for incorporation into products that stay on the skin; ideal for sports use. Mexoryl SX, on the other hand, is water soluble making it suitable for day wear formulations. When combined together, you not only get better protection, but you also get the benefits of the water and lipid solubility of each molecule. The result is a sunscreen that not only feels great going on, but that also continues to deliver upon exposure to water or perspiration.

So yes, Anthelios 40 is a good sunscreen, but if you’re looking for the best sunscreen to protect you and your family, consider these products that contain both Mexoryl XL and Mexoryl SX:
