Most importantly, this stuff works! And I absolutely love that it’s not greasy. My face isn’t shiny or slick when i apply it. I’ve had no issues with my skin tolerating this sunscreen.

Great daily sunscreen with lightweight feel
Size: 1.7 Fl Oz (Pack of 1), Size: 1.7 Fl Oz (Pack of 1)
I’ve been using this sunscreen daily and I really like it. It feels very light on the skin, absorbs quickly, and does not leave a greasy or heavy feeling. It also works well under makeup and does not cause breakouts. I feel my skin is well protected from the sun and it’s gentle enough for everyday use. I highly recommend it for anyone looking for a reliable sunscreen.

Great for oily acne-prone skin
Size: 3 Fl Oz (Pack of 1)
I have oily, acne-prone skin, and this sunscreen has worked really well for me. It doesn’t feel overly greasy or too dry, and it sits nicely on my skin without making my face feel heavy.
I’ve been using it for a long time, and honestly, it’s the only sunscreen I keep going back to because it works so well with my skin.
It feels comfortable for daily use and gives good protection without causing extra breakouts for me.

Great for oily skin!
Size: 3 Fl Oz (Pack of 1)
Definitely leaves white cast, I’m pretty fair skinned, makes me look like a ghost. Just rub it in your hands first, breaks into the mineral so minimize the white cast look. It feels lightweight and as someone with pretty oily skin it does a pretty good job!

Great for Oily, Rash-Prone Skin, But Be Wary of the Residue
Size: 1.7 Fl Oz (Pack of 1)
This sunscreen is a really solid option if you have sensitive, rash-prone, and oily skin like mine. I’ve found it’s one of the few sunscreens that doesn't cause any irritation, which is a huge benefit for me. On top of that, it leaves a truly matte finish, so I don't feel greasy or shiny throughout the day.
The only reason I can't give it five stars is that it leaves behind small, dried white bits on my face. They can be a bit annoying and make the application look a little messy.
Overall, it's a good sunscreen that works well with my skin type, but the white residue is a definite drawback.
