Many women with mature skin also suffer from adult acne, according to Jaliman. Pimple-prone ladies should steer clear of foundations that contain silicones, mineral oil or thickening agents, such as isopropyl palmitate. "These ingredients clog pores and tend to make acne worse," says Jaliman. Instead, opt for a foundation with breakout-clearing salicylic acid, such as Clinique Acne Solutions Liquid Makeup, $27.

How to Use It: With clean fingertips or a foundation brush, apply light layers of product to the center of the face and blend out, building the coverage as needed. For more localized coverage, use sparing amounts of a creamy, anti-aging concealer on blemishes and dark spots. Glaser recommends Eve PearlFx Liquid Salmon Concealer & Eye Brightener, $40, which contains wrinkle-fighting retinol, vitamin E and aloe. Just be aware that retinol may irritate sensitive skin.

Dry, aging skin often doesn't hold product as well, so look for water-resistant foundations that have a high-melting point, which prevents them from sliding off skin, Glaser explains. Elizabeth Arden Flawless Finish Perfectly Satin 24HR Makeup, $38.50, stands up to heat, sweat and humidity. It also contains a protective broad spectrum sunscreen SPF 15 and light diffusing properties to diminish the look of fine lines.

How to Use It: For precise application, employ short, light-handed strokes with a foundation brush. For a sheerer, more even finish, opt for a BeautyBlender or sponge.

Bobbi Brown Intensive Skin Serum Foundation, $62, is ultra lightweight and has a texture that feels more like BB cream than foundation. Formulated with extracts from goodies like lychee and bamboo grass, the serum gives skin a concentrated pick-me-up and dewy finish. To boot, it contains a whopping SPF 40 to prevent future damage.

How to Use It: Feel free to choose between a sponge, brush or your fingertips, depending on how precise you want your coverage.

Estee Lauder Perfectionist Youth-Infusing Makeup SPF 25, $45, has several age-defying powerhouses working together: a lightweight serum-infused formula for a brightened finish, hyaluronic acid for moisture, peptides to promote the skin's natural collagen, and elastin products to diminish the look of fine lines.

How to Use It: With your fingers or a foundation brush (try Estee Lauder Sculpting Foundation Brush, $45), apply product up the cheekbone, across the chin and jawline and in the center of the forehead. Use quick upward motions to blend from the center of the face out.

Meet the future of foundation: Cover FX Custom Cover Drops, $44, contain concentrated pigments that you can add to any skin care product to create a custom formula. Blend it with your favorite water-, oil- or silicone-based moisturizer, serum or primer to create a whole new product with your ideal concentration and texture. The drops contain pigment and only pigment, so as long as you have a skin care product that works well for your skin, you're safe to get mixing.

How to Use It: Squeeze the Cover Drops into the product of your choice and mix together with your fingertips. For a sheer tint, use one drop, for medium coverage use two and so on. Apply it with your fingertips from the center of your face toward the edges.
