Customers love the CoverGirl Outlast Stay Fabulous 3-in-1 Foundation + Broad Spectrum SPF 20 ($12) because it has multiple uses. It's a primer, concealer, and foundation rolled into one formula. It's very buildable, so you can choose to wear it sheer or apply a few layers for more coverage. It also has SPF 20 in it so you will be protected from sun damage.
