I’ve used this product for a whole summer. I worked out side for +16 hour days and I never got sun burnt once with this. I gradually tanned as the weeks went on (as expected with any sunscreen). But I was never burnt. This sunscreen DOES make you look grey and ashy, no matter what your skintone is. It has that grey undertone that no living person has. But it never clogged my pores, no matter how much I sweat working outside. Do put lotion on before your day starts so it doesn’t dry out your skin, because the first ingredients are alcohols. One bottle lasted me all summer and more so the price isn’t too high to pay for a product that lasts a long time.
