Hi! I would recommend trying the Urban Decay Naked Skin foundation since there is coverage but it looks completely natural. For additional covering of blemishes I would recommend Too Faced Absolutely Flawless concealer-it's better to have a sheer foundation and add extra coverage where you need it rather than putting a thick mask over your whole face to try to cover everything at once. Hope this helps!
I use Clinique Acne Solutions. I'm the same age as you and have concerns about coverage and acne as well. I you will have to try out various shades to get your perfect one. The foundation is very natural looking and makes your skin look flawless.
