Great mineral sunscreen
Style: SPF 50 Lotion, Size: 6 Ounce (Pack of 1)
Great mineral sunscreen, rubs in well, protects well during high UV times, doesn't sweat off, not strong smell. Used this for fist time on a 95% high humidifier day while walking around Pittsburgh between 11am-3pm. No burning at all. There is a film left but that's for almost all sunscreen, so not any difference with this one. Easy to rub in and may leave a slight white coat but not as noticeable as some other mineral products. I will buy this again and recommend.

One of the bests
I’m a full time trucker and I wear sunscreen everyday. In my opinion, this is the best sunscreen out there. It feels like makeup primer on skin, it dries clear. The white cast has always been a turn off for me looking like a geisha to work or the white cast residue on the collar was icky.
Although this feels oily and shiny a bit glass skin but not sticky just powdery feel.
I recommend it 👍🏻

GREAT COVERAGE!
Even, protective coverage. Great SPF to keep you safe from damaging UV! I apply evenly over face, let set, then I can put my makeup on.

Not for oily skin
Not the best for oily skin. No matter how little I put on, it feels greasy and makes me look so shiny. This is even after I put on sunscreen setting powder. I’ll keep it and use it for days I’m not in the sun much. The days I am outside a lot, I will have to stick to my black girl matte sunscreen.
