Long-awaited sunscreen cleared in U.S.

The FDA announced on July 24, 2006, that it has approved a L’Oreal over-the-counter sunscreen called Anthelios SX that contains an ingredient that blocks the type of harmful ultraviolet radiation linked to some cancers.  This product contains three active ingredients including ecamsule that blocks deep penetrating ultraviolet A rays. Ecamsule has not been marketed in the U.S., but it has been marketed in Europe and Canada as Mexoryl SX since 1993.  Mexoryl SX is "particularly effective against short UVA waves" and doesn't degrade when exposed to the sun for long periods of time, unlike other UVA filters, according to a L'Oreal news release.  The other two active ingredients are avobenzone and octocrylene, which are generally regarded as safe and effective.  Anthelios SX has a sun protection factor (SPF) of 15.
In 28 studies of Anthelios SX that included more than 2,500 patients, side effects were rare and mild. The most common side effects in patients were acne, dermatitis, dry skin, eczema, abnormal redness, itching, skin discomfort, and sunburn.  Although this product protects against both UVA and UVB rays, it is recommended that in addition to wearing sunscreen consumers should limit their time in the sun and wear protective clothing to further prevent skin damage.
