Key Point: Undertone
Dark or light, the foundation of foundation is undertone. There's no faster way to looking worn out or just plain weird than smoothing the wrong foundation into your face.
Non-Caucasian skin usually has warm undertones. Iman, Salma Hayek and Lucy Liu are all warms. If this is you, look for a yellow-based foundation.
Very dark skin, like Naomi Campbell's, tends more toward cool undertones, which calls for a foundation with a pink base.
- If the veins on the inside of your wrist are bluish, you're a cool. If they're greenish, you're a warm.
- African-American women often have lighter skin on the cheeks and forehead; use multiple shades of foundation to help even everything out.
Cheeks are up next. After you finish, you may want to trade in your blush.
