Review: Horrible - So bad ruins makeup and leaves white cast
Review: Great for Oily Skin, No Lasting White Cast - 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.

### ⭐ Horrible
*by F***I on 28 June 2026*

So bad ruins makeup and leaves white cast

### ⭐⭐⭐⭐⭐ Great for Oily Skin, No Lasting White Cast

### ⭐⭐⭐⭐⭐ Acne-friendly Spf! Definitely recommend :)
*by C***E on 13 March 2026*

I am really impressed so far with this sunscreen. I’ve been looking for a good spf and came across this one, so far so good! This is a mineral-based sunscreen which is recommended for those who have sensitive/acne prone skin. I have sensitive/acne prone/oily skin and this product has not broke me out. It leaves no white cast, doesn’t pill, and no scent. It’s the perfect base for your makeup! Leaves my skin feeling very soft and smooth with a subtle matte finish. Not greasy or too heavy, a little goes a long way! I would recommend this product to anyone who is looking for a good acne-friendly/ sensitive mineral-based spf. :)
