Your ideal foundation type is a balancing liquid foundation that offers full coverage.

"Balancing foundations generally contain moisturizers like glycerin and 'sebum soakers' like silica shells, says Vickery, senior scientist at P&G Beauty. "The key is to engineer these foundations in a smart way, so they interact with the skin rather than [compete with] each other." Find a good liquid foundation that can be layered to achieve a natural, yet full coverage finish. (Try: Shiseido The Makeup Dual Balancing Foundation SPF 17, $36.

TIP: "For heavier coverage on skin that tends to be dry, look for a creamy liquid [or cream stick] that contains hydrating properties such as vitamin E," says Bass. If your skin tends to be more oily, choose an oil-free formula.
