OK without makeup, but not so smooth under it
I got this for my husband to use to even out his skin, and he seems to like it OK. When I use it, I find that it doesn't quite go on as smoothly as I want it to when wearing under makeup. If you don't need this with makeup, I'd say go for it, but if you are using it as a primer, it is not my favorite.
Primer or Foundation
I bought this to go under the Colorescience SPF mineral powder to help with oil control. It's a little heavier feeling on my skin than typical primers and doesn’t really control my end of day shine. Too heavy feeling to wear in summer months in Texas.
