I have very fair skin and when not wearing sunscreen, I will burn to a crisp in less than thirty minutes. What drew me to this was the SPF 50 because the higher the SPF content for me, the better. It doesn't feel greasy at all and one application will last roughly an hour and a half. Used this on the water directly in the sun and I don't have an ounce of sunburn on me. The smell is amazing and makes me want to use this as a lotion.
