As of June 2012, here is a list of some of the ingredients permitted in Europe and Japan but not in the U.S.:
Of these ingredients, I think we will be seeing the most from Tinosorb M and S in the years to come. Thankfully, Tinosorb S is now available in the U.S.
Unlike some other chemical sunscreens, Tinosorb is highly stable, so it doesn't break down in the presence of light or air. Yet, the best part of Tinosorb is that it is the most effective UV protection available for both UVA and UVB rays, according to a 2007 study from the European journal Pharmazie. Tinosorb’s secret? It is not just a physical sunscreen that prevents UV rays from hitting the skin, or just a chemical sunscreen that stops transmitted rays from damaging the skin - but actually does both! That's right - Tinosorb shields and protects the skin. That's like a man who stands up for you in public and cuddles with you while watching The Notebook. Best of both worlds! Based on current studies, it does not seem that long-term exposure to Tinosorb has any damaging effects, nor does it seem that irritation is common. Still, Tinosorb is a relatively new ingredient, and further studies need to be done. That said, it has been on the market for several years in Europe, and irritation studies have been minimal.
While many dermatologists still swear by physical sunscreens, like zinc and titanium oxide, there are still many patients who are constantly looking for alternatives. There are many new options brewing on the horizon that are currently only available in Europe and Japan, but one great chemical sunscreen, Tinosorb S, has made it to our shores. I highly recommend it for anyone who dislikes zinc and titanium oxide and who wants an effective, broad-spectrum UVA/UVB chemical sunscreen! What do you think about buying sunscreen overseas?
