this is one of the best all physical sun blocks I've tried. Some history: I have exceptionally sensitive skin and cannot use any chemical sunscreens (even the of the european variety) w/o suffering from at best a nasty break out to at worst contact dermatitis. normally I wear Devita daily solar protective moisturizer 30 under MMU during the day for sun protection (and it works very well). I go for a short hike every morning, and though I'm only out in the sun for an hour at most that is plenty of time for my skin to burn. I picked this up at a local health food store since it was an all physical block and it was silicone free (another thing that I'm highly reactive to). It wears wonderfully and doesn't budge even though I'm sweating, and it doesn't break me out. it does go on greasy w/ a slight white cast, but it mattes down w/in 5 and doesn't feel greasy or heavy on my skin. once it dries I don't notice a white cast, but I'm also very pale, so it may not work w/ someone who isn't fair skinned. though it is only an spf 18 I haven't burned while wearing it, and I'm thinking of using this as my daily s/s under MMU for days I know I'm not going to be in the sun much. overall I'm very pleased and will certainly repurchase. ingredients: Active Ingredients: Titanium Dioxide 7.6%, Zinc Oxide 0.4%.
