Amazing stuff!!
Love love love this stuff! You do have to spread it out well to not go right through it but it doesn’t take more than a thin layer to protect you all day!!

amazing product, a little too pricey
it worked amazing while we were trying to swim in the ocean and snorkel in the ocean. The only downfall I have of this is the price is so much for such a little amount.

My go to brand
My go to brand. Other brands I have to reapply constantly and still have sunburn. I love this brand and the stick is even better for applying sunscreen. Very reliable without any mess!
