Good coverage
Style: SPF 50, Size: 5 Fl Oz (Pack of 1)
Great sunscreen and when applied liberally my face doesn't get burnt. That has always been a problem with my skin all my life so I'm happy for that sort of coverage. The formula is a little greasy and there is a white caste but I use it to my advantage as it dims the red spots on my face and brightens my under eye. I try not to leave the house without applying.

Smooth sunscreen

Great for mature skin. Not easy finding something for mature skin that doesn’t cake or flake off. Moisturizing. I will buy again !

Very glowy

I just opened this to try it so I can't speak on if it breaks me out but the expiration date is good it doesn't expire until next summer. It's not thick at all very liquid actually but not a messy. I skipped moisturizer today to see how the hydration will be. I have severe dry skin so we will see. Very oily, glowy, moisturizing. I used it on my face and arms. It left a beautiful glow on my face so we will see how long it's takes to soak in. No strong smell which is nice and it's a large bottle!

Very moisturizing but clogged my pores
Style: SPF 50, Size: 5 Fl Oz (Pack of 1)
I like the texture of this sunscreen a lot, and it gives me a nice glow. However, it did cause me to break out a lot with small whiteheads so I had to discontinue using it.
