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.
Review: Gentle and effective sunscreen for sensitive skin - It provides strong sun protection (SPF 50+) and works well under makeup without pilling. I also noticed it helps control excess oil throughout the day, leaving a natural, non-greasy finish.

I love this sunscreen, it's great for oily skin... It does leave a little white cast but it fades fast. It feels soft and hydrating, doesn't break! Suitable for sensitive skin too.
