Weightless, sheer, not greasy formula!
Size: 3 Fl Oz (Pack of 1)
I have tried an embarrassing amount of sunscreens from both high end brands sold at places like Sephora and Nordstrom to dermatologist brands to drugstore brands. This cerave sunscreen is literally perfect. For reference I am in my 30s with fair skin and combo skin. For reference I do not like the other cerave mineral sunscreens. They are extremely white. I do like the cerave ultra light daily moisturizer with spf 30 (I think it’s called) but it’s not waterproof. Here are the reasons why I love it SO much: -waterproof! (Lasts longer during a hot summer day AND I can wear it to the pool/beach with the kids. Truly a do it all sunscreen!) -wears really well under makeup -not greasy or oily -no white cast or film -cosmetically elegant -not drying and provides some moisture -didn’t cause sensitivity, acne or eye burning -i can even put it on my kids without them complaining -feels silky soft and weightless. Truly one of a kind. -cerave is a brand I trust -great mix of zinc and chemical active ingredients for effective protection -great for my combo skin -affordable, decent amount of product -convenient squeeze bottle that doesn’t leak I’m so glad I found this! The #1 reason why I love this is because I trust the protection of cerave and it wears beautifully under makeup! The only thing I can think that would make this better would be if it was a spf 50 but it’s perfect otherwise. I’ve already worn it to the pool and it preforms really well, even on a really hot day being outside for a long time! I live in south Texas. This is literally one of the only sunscreens my husband can stand wearing on his face. So it’s man approved for men who hate wearing sunscreen lol! I didn’t even realize it was labeled for face and body. Ive only been wearing it on my face, neck and chest. I need a bigger bottle for whole body application as we go swimming a lot! I purchased this sunscreen with my own money and this is NOT a paid review. I just really like it! :)

Non-greasy and doesn't damage clothing
Size: 5 Fl Oz (Pack of 1)
I looked hard for a high quality sunscreen that wouldn't turn my clothes orange and this meets my needs. It is a strong, 30 SPF, but it is not heavy or greasy. It is effective, and it does not discolor my clothing.

A must for summer!
Size: 5 Fl Oz (Pack of 1)
My go-to sunscreen. It’s clean, lightweight, and doesn’t leave that white cast like a lot of mineral formulas. I have blonde extensions and this is one of the only ones I’ve found that doesn’t turn them pink, which is huge. Wears really nicely on the skin and layers well—definitely a staple for me.

Overall good basic
Size: 3 Fl Oz (Pack of 1)
I was looking at mineral sunscreens because they are more natural, but I found the chalky film they leave on the skin to be undesireable. Still, I did not want a fully chemical formula. I was able to find this hybrid that also has hydrating ingredients and ceramides for the skin. It goes on light and provides great coverage. It is a little shiny/greasy however which is why I dropped a star.
