Eyes burn but good for face
Size: 1.7 Fl Oz (Pack of 1)
This sunscreen is really light weight and gives me a glow without being to greasy and heavy. I love this sunscreen but it makes my eyes burn throughout the day

Lightweight and it works!
Size: 1.7 Fl Oz (Pack of 1)
I love how this sunblock goes on so smoothly. I use it daily and have not gotten burned in this extreme Florida weather. I also like that I don’t sweat using it, unlike some other sunscreens I’ve use.

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.
