Lightweight and no white cast
Color: Non-Tinted, Size: 1.7 Fl Oz (Pack of 1), Color: Non-Tinted, Size: 1.7 Fl Oz (Pack of 1)
I really like this sunscreen. It feels lightweight on the skin, absorbs nicely, and doesn’t leave a white cast. It gives good hydration without feeling greasy and works very well under makeup.

Nearly Perfect Sunscreen
Color: Deep, Size: 1.7 Fl Oz (Pack of 1)
Sunscreen is lightweight and smooth. Also, does not leave my T-zone super oily like other sunscreens. Only issue is the shade is still not dark enough, so it takes a little time to fade into my skin.

Great for Sensitive Skin
Color: Non-Tinted, Size: 1.7 Fl Oz (Pack of 1)
My face has always been sensitive to sunscreens, so I have to be careful with what I use on my face. (Others can cause burning sensations). This sunscreen is great. I had no issues, and unlike other sunscreens, sweat running didn't cause my eyes to burn or water which was great. Keeps my skin protected against the hot Florida sun, so it works!
