It is well understood that for good sun protection both UVA and UVB needs to be blocked. As the sun is a trigger for many rosacea sufferers, good sun protection is a must.
Lets look at Mexoryl. Mexoryl SX (patented by L’Oreal) is a photostable UVA filter that is used in sunscreens available in many countries. It is not currently available in the United States
John Stossell from ABC’s 20/20 asks why the FDA hasn’t yet approved Mexoryl in the United States.
According to Dr. Darrell Rigel, clinical professor of dermatology at New York University,
“Mexoryl is the No. 1 individual ingredient in terms of protection from Ultraviolet A radiation”.
Mexoryl has been formulated into many sunscreens in Europe and Japan where it has been available for several years. In some formulations it has been shown to be well tolerated by those with inflammatory skin conditions.
Dr. Soldo likes the La Roche Posay forumulation with Mexoryl. Although not approved by the FDA it can be sourced in the US. Anthelios, which also contains titanium dioxide and Parsol 1789, is available in Canada and via some internet sites.
