Great sunscreen & works for kids - even used in resorts!
Style: SPF 50
Terrific! I don’t feel it is as good as chemical ones but my favorite non-chemical one. Used on a long vacation and it did the job! Also didn’t cause pimples like other thick versions of this.

Protection
Style: SPF 50
I love this product, especially my husband because it’s all-natural. It contains minerals that leave a slight white residue on the face. While it would be nice to have a clearer texture, it does a beautiful job of protecting you from the sun.

Oily skin win
Size: 1.7 Fl Oz (Pack of 1)
As someone that refuses to spend $40 on a 1 oz bottle of facial sunscreen, I decided to give this one a try. For some background, I have very oily olive skin. I've been using tretinoin for 6 years. Currently, I've been using the .14% of tret for the last year or so. With that said, it's interesting balancing the dryness of tretinoin with my oily skin. This sunscreen is fantastic. It doesn't make me more oily. The price point is good. No breakouts. Doesn't feel heavy or greasy.

Non-irritating, daily sunscreen for sensitive skin
Size: 1.7 Fl Oz (Pack of 1)
Sunscreen does not leave a white cast on the face, which is great! I have sensitive skin, but this sunscreen doesn't cause irritation or dry out my face. Perfect for every day use. Definitely will buy again.

Love this sunscreen for my face! Not oily. Cannot really feel it, very light. I wear it under my foundation and also alone.
