I have combination skin, prone to acne, and sensitive skin. Even though this is labeled as non-comedogenic and best suited for oily skin, I still experienced acne because the consistency of the sunscreen is really thick. It makes it hard to blend (really hard) and upsets my skin. It also smells a lot like alcohol, more so than most sunscreens, even those from this brand. I bet it's good for some skins but it simply wasn't for me.

Finally!

Size: 2.5 Fl Oz (Pack of 1)

I have been looking for a sunscreen that does not breaks me out or irritate my eyes and this was perfect. I wash my face in the morning and I put this sunscreen on. I don't need to use moisturizer since this is enough. It does leave my skin glowy which I like but not greasy. I notice even my dark spots are fading but because I do use this everyday. My skin is tan and it does not leave a white cast. I love it. If you have acne prone skin, oily and sensitive give this a try.

Finally! An SPF Hubby will wear!

Size: 2.5 Fl Oz (Pack of 1)

I've bought my husband at least a dozen SPFs--everything from drugstore to premium brands--and he won't wear any of them. He's 64 years old with oily, extremely sensitive skin (rosacea and dermatitis), and a tendency to sweat a lot in the summer heat, as he's very active. As for SPF, he hates the white cast, how heavy it feels on his skin, and how his eyes burn when he sweats and the SPF gets in them. But I keep trying. Since Eucerin was the only SPF I was able to tolerate after radiation, I tried this one for him. It's the only one he's liked. There's some white cast initially but it settles quickly. He says the lotion doesn't feel heavy, hasn't caused any irritation or breakouts, and doesn't bother his eyes either. He actually wears this one!!! I'm thrilled! Thank you, Eucerin!

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.
