Mexoryl, sunscreen
Mexoryl sun screen season is here.
Protect yourself from UVA, UVB.
The protection factor is only part of the story. A product with
an S.P.F. of 30 may have a UVA protection rating of only 2. Your
sunscreen should be a broad-spectrum one that also blocks
UVA radiation. Two ingredients now used in "complete" sunscreens
in cosmetically acceptable micronized forms are titanium dioxide
and zinc oxide.
Two other agents that offer broad-spectrum protection, Mexoryl
and Tinosorb, help to stabilize UVA protection during prolonged
exposures. They are available in Canada and Europe but have not
yet been approved by the Food and Drug Administration here.
Neutrogena, however, has a new product on the American market,
Ultra Sheer, with an S.P.F. of 55, that is said to do the job of Mexoryl.
It is also more affordable and is cosmetically comfortable. The
company uses a patented Helioplex technology to stabilize two
UV blockers, avobenzone and oxybenzone.
