Matte comfortable facial sunscreen
This is a great sunscreen! The texture is kind of odd at first but it dries down nicely and is the only facial sunscreen I have found that is NOT shiny or greasy looking! Most facial sunscreens will advertise no white cast and being "dewy," but I find them to make my face so shiny and greasy looking, especially because I also use a moisturizer. This one is great and does not add any shine to my face.

clear and light sunscreen
Used this sunscreen and it works really well.
It goes on clear and spreads easily. Not sticky or oily at all, very comfortable on the skin. Feels light and good for daily use.

Matte and definitely worth purchasing
Love it. It’s definitely matte, but doesn’t dry me out. I put it on with a light moisturizer, and have no issues with pilling. It feels more like a light oil when applying, but that feeling goes away in seconds. I like that it’s also water resistant. I get oily really easily, so I’ve been looking for an affordable matte sunscreen, and this seems to be working really well for me. There’s a sunscreen smell on application, but it’s not too overwhelming and goes away quickly. Overall, 10/10 would definitely recommend, and kinda wish I could gatekeep it.

Best sunscreen ever
Best sunscreen! Extremely smooth, it leaves your skin completely matte. It does not feel like sunscreen, it feels like a high end primer. It’s a gel not even a cream. I use it as my primer, since I have to put sunscreen on anyway, it serves as my primer before make up. I’ve always struggled with finding a decent sunscreen for my face that leaves no cast or hurts my eyes but this one is the best one I’ve ever tried. Matte, smooth, gel, does not hurt eyes, primer for make up. Amazing! And great value for the money.

Feels very oily right after applying
Ok, NON SPONSORED review. I bought this with my own money. It’s a great sunscreen, very lightweight and goes on clear. The only downside is, right after applying it feels like straight cooking oil on your skin. It’s a horrible, horrible sensory experience. But once you give it a couple minutes to dry down, it’s completely matte and feels like nothing. It hasn’t broken me out yet like other sunscreens I’ve tried, so that’s a plus.
