Easy to apply, neutral smell, and lasts long
I usually hate sunscreen, but this brand is acceptable. It doesn't leave a terrible waxy feeling on your skin, and it's easy to apply on your face. Also, it doesn't have an overpowering smell, which is nice.

Dry-touch but still uncomfortable to wear
It didn't rub in like regular sunblock, I suppose because the of the 'dry-touch'. But I could still feel it on my skin and was a little bit itchy. If you continue to rub it actually kind of peels away-then obviously negating putting it on in the first place. :(

It is a great sunscreen.
I love it, because it is no greasy and it feels like you don't have it on your face. It is a little expensive comparing to others but I think it is a good choice.

Have used it for years
One of the the best on the market because it is a broad spectrum sunscreen protecting against both UVA and UVB rays. But as with all lotions it must be reapplied after several hours.

Lightweight sunscreen for face, 30 spf, everyday mix with foundation
Style: Face Lotion - SPF 30, Size: 1.7 Fl Oz (Pack of 1)
Great sunscreen and it is travel size! This suscreen is 30 spf, has a yellow tint, which works well as a facial sunscreen, while toning redness. It mixes well with three types of foundations. It is not sticky, absorbs well. Smells good.
