### ⭐⭐⭐⭐⭐ Great mineral sunscreen
*by A***Z on June 25, 2026*

### ⭐⭐⭐⭐⭐ Good wear
*by A***E on July 10, 2026*

Love this sunscreen. No white cast. No piling. Good under my light makeup of concealer, blush and powder.

### ⭐⭐⭐⭐⭐ Great for Oily Skin, No Lasting White Cast
*by C***F on December 26, 2025*

I have very oily skin, and I’ve tried many sunscreens, but this one is my favorite so far. As a tan girl, I was a little worried at first because when I applied it, there was a slight white cast. However, it disappeared quickly and blended beautifully into my skin. It leaves my face smooth, comfortable, and not greasy at all. It feels lightweight, sits well on the skin, and doesn’t make me look shiny or heavy throughout the day. I also love how gentle it feels—no irritation for my sensitive, oily skin. If you struggle with oily skin and want a sunscreen that looks good after application, this one is definitely worth trying.
