Great product!
Color: Medium, Size: 1.7 Fl Oz (Pack of 1)
Really wish I had found this sooner. We spend a lot of time outdoors for baseball and this is perfect for the hot summers. I put this on with a little blush and it looks better than my foundation and protects my skin. Isn’t greasy like regular sunscreen. Skin isn’t dry after wearing either.

Doesn’t stink, not super thick and minimal white cast
Color: Medium, Size: 1.7 Fl Oz (Pack of 1)
The product is a lot thinner than other sunblocks. VERY creamy! The tint is sheer but it’s less sheer than I actually thought. Which is fine bc I’ll use it as more natural makeup in the summer time if I go anywhere. It’s not so much that you can tell either though! My sister who sees me every single day told me my skin looked “very youthful” today and didn’t know it was tinted spf. She had smelled my face when I wore another spf and had agreed the other one STUNK so badly but we didn’t smell anything on this one. I am fairly light but I got the medium based on reviews I searched for on tiktok. I figured the white cast would lighten it up somehow but there is NO WHITE CAST! But the color is still fine bc it isn’t chalky like la Roche posay tinted liquid spf. This is very natural! When I applied this product it looked SO SHINY. I almost regretted it…. But 20-30 min later (I applied it then immediately drove 15 min to my sisters house) the product had set and it has a much more natural and dewy but not crazy oily finish. I love it so far. I do consider myself to have very sensitive dry/combo skin and am in the process of repairing a damaged skin barrier. This didn’t itch or burn or anything. I did notice it started pulling after rubbing it in so much but I did kinda rush my morning routine this morning. I’ll update if it wasn’t my bad.
Update: it’s been 5 hrs since I applied it. It’s definitely not going to be doubling as a moisturizer. I don’t feel like it’s dehydrated but it’s not moisturizing like other sun screen has been. But maybe just expected it to since it’s cerave but it’s not marketed as such. But that’s ok with me bc I’m more worried about the SPF part of the product.
Shade: at first I didn’t notice bc I was just indoors…. But it has enough tint for someone to notice the change in skin tone between my face and body so now I’m going to need to order the light one

Outstanding sunscreen.
Color: Medium, Size: 1.7 Fl Oz (Pack of 1)
I just ordered my second bottle of this sunscreen. I live in Florida so sunscreen is a big necessity.
Love it. The little tint is perfect and it feels great. It is not overly greasy. I do apply a little powder
and a little blush then I’m on my way out the door. I highly recommend this product.

The perfect summer tint with SPF protection
Color: Medium, Size: 1.7 Fl Oz (Pack of 1)
I am really enjoying this CeraVe Hydrating Mineral Sunscreen! I am always on the hunt for products that give me a quick, healthy glow without having to put on a full face of makeup, especially during the summer, and this completely hits the mark for easy coverage.
The texture is beautifully lightweight and glides on so smoothly. I was honestly a bit nervous that it would leave that heavy, sticky, suffocating feeling that so many sunscreens do, but it is completely non-greasy. Plus, a huge win for me is that after wearing it for hours, it doesn't migrate or burn my eyes at all.
The only reason I'm knocking off one star is the shade range. I picked up the Medium tint, and while I can definitely make it work for the summer when I have a bit more color, I really wish they offered an "in-between" shade option between Light and Medium.
If you're looking for a comfortable, daily SPF that lets your skin breathe while evening out your complexion, this is a fantastic staple to have in your routine!

Go-To for Reef-Safe & Light-Weight Sunscreen
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
Favorite sunblock to travel with. Appreciate the simplicity of it, and the fact that it rolls on and rubs in smooth. Of course the iconic scent is also a plus.
