Clear face
I love using Eucerin products. It’s safe my skin and protects. It’s my first time trying the sunscreen so far I like it. I don’t do makeups. It has a clear view on my face, doesn’t leave any whit spot le so I love it.

Best face sun protection
My Neutrogena one stung my eyes and made me constantly tear and this is soooo much better. It feels light and dries down well without feeling greasy. Also it didn't make my skin react. A++

Greasy but light
It's very lightweight and is definitely hydrating
it's lightly greasy after its dry and it is not matte but has a dewy shine to it ,
I have tried many sunscreens and settled on this one as it just has a nicer feel to it and is easier to apply everyday, it goes on quickly and leaves no white streaks at all
Its more watery than thick
And does NOT peel whatsoever
I Would definitely recommend this as a daily Face sunscreen if you not mind the shine it has to it.
Its convenient
Yet the bottle is small and last only about a 1 to 3 weeks depending how many times you use it
To bad
They DO NOT MAKE A BIGGER SIZE
