Real Review after 2 months
Size: 3 Fl Oz (Pack of 1), Style: SPF 55
Great and easy to use, because of liquid based. No need to reapply again for every 2 hours. Because I tried it every day

Works great
Size: 3 Fl Oz (Pack of 1), Style: SPF 55
So no Sunscreen worked for me. I tried almost everything. Then I tried this one. Its seems pretty well. That absorbs the skin and does feel greasy. Very nice.

It's ok. Leaves a white cast and burns the eyes.
Size: 3 Fl Oz (Pack of 1), Style: SPF 55
Its good as it's not too heavy and definitely not greasy. However, it leaves a horrible white cast. And I have pretty fair skin. I have to use some type of bronzing drops before hand. Or put a tinted SPF moisturizer on top. It's pretty bad on that and it stings my eyes SOO badly I've had to wash it off! Burns that bad. So if your eyes are sensitive to sunscreen around the eyes. This will sting and burn, dont use it around the eyes if you can help it.
