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.

Favorite
Invisible sunscreen and the brightening really helps too. Can be glossy, but if you let it absorb into the skin for 30 mins and the blot some of it off it can help with the glossy ness
