Great feel but a bit strong of a smell
I absolutely love the feel of this sunscreen, since it feels really smooth and light weight. There is no white stain from sweating and feels really moisturizing. The only thing I dislike is the strong fragrance. I personally don't like fragrance in my beauty products, but I wanted to try this sunscreen due to the high reviews. I think this is a great sunscreen to buy, but for me personally, I would not buy again simply due to the smell though it does smell good. I will try out the fragrance free version.

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.
