I love this stuff. It's non-comedogenic, so it doesn't break me out. I've noticed a considerable difference in my acne scars after using it for a couple weeks. It is a little greasy and there's a very slight white cast, but I don't mind because I just let it dry and then put some powder over the top. Plus, the cast is easy to rub in and makes my skin tone look more balanced (I am white, though). Hope this helps!

Good sunblock

Size: 6.76 Fl Oz (Pack of 1), Style: Lotion (SPF 50)

This is my go-to sunblock reconnect by my dermatologist. It has a good skin feel, and seems to do the job required.

Perfect protection for daily use

Size: 6.76 Fl Oz (Pack of 1), Style: Lotion (SPF 50)

This is my go-to sunscreen for my daily use. I have stuck to a strict skin care routine and at the end, it’s extremely important to have a sunscreen to seal the deal. And this does just that. It doesn’t leave that nasty white streaks from the sunscreen and goes on very nicely. Out of my months of using this I have never been uncomfortable with it and the smell is very refreshing unlike other brands of sunscreen. Most importantly, this doesn’t feel greasy or overly slick. Perfect balance.

Great

Size: 6.76 Fl Oz (Pack of 1), Style: Lotion (SPF 50)

While it is a bit thick, that can be great for sweaty summer activities (also it's purpose)! It does not leave a white cast (on me, though I am pale, I have experienced this with other sunscreens) and smells okay, not great but like a sunscreen would be expected to. It's not a super strong scent and does not burn my eyes. Sits good under my makeup as well.

Great protection and not greasy.

Size: 6.76 Fl Oz (Pack of 1), Style: Lotion (SPF 50)

This sunscreen is great. It is not greasy and protects for a long time. I have had a few battles with skin cancer, but feel confident that this stuff will protect me. Yesterday was hot and sunny and my skin was still protected after 4 hours on the golf course.
