Great - effective sunscreen that isn't oily
Size: 3 Fl Oz (Pack of 1), Style: SPF 50
Works well, doesn't make your skin oily, almost disappears when you put it on. Made for faces but of course works anywhere else as well.

It is a good sunscreen, but if your skin is very oily, think again.
Size: 3 Fl Oz (Pack of 1), Style: SPF 50
I have tried many, MANY sunscreens, and this one is in my top 10, but not at the very top. Why not? Well, what I like about it is that you get a good amount for an excellent price. It's lightweight, but not extremely so, and this size can easily last you 3 months without any problem. However, while it's made for oily skin, it's not that light. After just a few hours of application, it can leave your skin feeling greasy, especially if you sweat easily. It doesn't leave a white cast, but it does leave a slight, shiny finish. Reapplying isn't very comfortable. If you use it just once a day, it's fine, but if you apply it more often, your skin will feel a bit heavy and oily. I think this sunscreen is better for specific occasions rather than for daily use. If I had to choose a sunscreen for daily use, I would pick one with a lighter formula, like Fusion Water from Isdin.

stellar sunscreen for face- sensitive skin friendly, feels good not greasy on, timeless
Size: 3 Fl Oz (Pack of 1), Style: SPF 50
I used to try out different brands and this is the one I've got to have for my face- safe on sensitive skin and just feels really nice and not greasy putting on, sometimes I get stuck borrowing so now I get a few and have them in various places. Also, I appreciate they don't change the packaging or add other versions so I can grab and always feels great and works on

Works great but does not hold up to sweat
Size: 3 Fl Oz (Pack of 1), Style: SPF 50
Dissolves with intense exercise then burns eyes and makes a mess, but otherwise works great.
