Eucerin sunscreen spf 50
The best sunscreen I’ve ever had. No white cast, no clogging pores. Goes on smooth and silky. No flaking off. Absolutely love it. I’m a dark skinned black woman for reference

Eucerin for the Win...Again!
I love this tinted sunscreen. It's so lightweight and blends in really well. Since it blends in, it is good for all shades of skin. It doesn't have a strong smell like a lot of other sunscreens have, so that is a huge bonus. So far I'm really loving it. I am definitely a Eucerin girly. I love all things Eucerin at this point.

A hydrating sunscreen but won’t provide the coverage
I’ve been using CeraVe sunscreen, so that’s my baseline. It’s thicker, slightly pigmented, and very hydrating.. Switching to Eucerin felt like moving from a cozy blanket to a light sheet. It’s definitely thinner and less pigmented, so at first it didn’t give me that same immediate glow or coverage I was used to. That said, on its own, it’s still a good sunscreen. It spreads easily, feels comfortable, and does the job without heaviness. After using it for a while, I’ve kind of settled into a rhythm: • If I want a bit of coverage and that hydrated, supple finish → I reach for CeraVe • If I just need straightforward sun protection → Eucerin works perfectly fine One small downside is the packaging. The pump is convenient, but toward the end, I can already tell there’ll be product left that’s hard to get out since you can’t really squeeze or open it easily. Overall, I’d say Eucerin is a solid, lightweight sunscreen. Just don’t expect that tinted, slightly “makeup-like” effect if you’re coming from something like CeraVe. It’s more of a quiet, reliable everyday option than a multitasking one.

Ok for sunscreen
Works fine as sunscreen. Did make me look a little red but might be a reaction as I have very sensitive skin. Didn't notice any color change so basically it's just sunscreen.
