    • 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. ... show more

    • Awesome!
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.

Nice and light and goes on smoothly. I don't know white shadow and no perfume.

    • Good Ingredients Focus, But Feels Oily on My Skin
I’ve been using this sunscreen for about 4 days, and I have mixed feelings about it. I have naturally oily skin, and this product definitely adds to that. It feels a bit heavy after application and doesn’t absorb as cleanly as I would like for everyday use. If you already have oily skin, this may not be the most comfortable option, especially in warmer weather. On the positive side, there is no white cast at all, which is great, and I didn’t experience any irritation or itching. It feels gentle on the skin, which I appreciate. One thing that frustrated me is the confusion around this product. I originally bought it thinking it had a high rating on the Yuka app due to clean ingredients, but later realized there is another product from the same brand with very similar packaging that actually has that rating. That can be misleading for buyers who care about ingredients. I do hope the brand moves toward making all of their products more health-conscious. After all, health should come before beauty - if we can protect our overall health, that matters more than just protecting the skin. Overall, it’s not a bad sunscreen, but for oily skin types and for those specifically looking for top-rated clean formulations, it may not fully meet expectations. ... show more

    • Phenomenal
Has a slight white cast but it’s super light and easily absorbed by the skin. If you have fair skin it’s perfect but with some tones like olive skin or brownish would show the white cast.

Review Image by RedGG
I hate to write bad reviews, but this sun screening pissed me off. Not only is it super drying but it has a significant white cast. When you wear it is sticks to your eyebrows too and around your mouth to leave a white film. I'm so so disappointed b/c I also looked at the videos before I bought this and they are inaccurate. I'm attaching a picture where you can see the white cast even after I rubbed it in. I would give this 0 starts but giving this one b/c it doesn't irritate your eyes. ... show more

    • Ok sunscreen. Leaves a mild white-cast and thicker consistency.
Roundlab (Birch) has been my go-to sunscreen product for about a year now, so I decided to try their mineral sunscreen. It is great for protecting your skin, but I notice that it does leave a mild white-cast, and the consistency is a bit thicker than their other products. I would stick with their moisturizing sunscreen. ... show more
