Your best foundation type is a tinted moisturizer or light, balancing foundation.

"Tinted moisturizers are great as they cover while hydrating ... and they can be mixed with a heavier cream foundation to hide problem areas," says Bass. Ones to try: Shiseido The Makeup Dual Balancing Foundation SPF 17, $36, and Sonia Kashuk Tinted Moisturizer, $11.99.

TIP: To get a flawless look, "apply sheer foundations with your fingers and blend by tapping into the skin, rather than using big strokes which can cause streaking," says Bass. "Alternatively, you can use a foundation brush and then finish by blending with a sponge using the same tapping motion."
