I bought this for Hawaii as a reef safe option. I have sensitive skin so I have to be careful about what sunscreens I buy - this worked great and did not irritate my skin. It's a bit thick but it's an SPF 50 so that's not a surprise. A bottle lasted an entire week in Hawaii. A great product for sensitive skin!
