Instantly look gorgeous with our primer on primers.

It's what's underneath that really counts.

So before you slip on foundation, apply eye shadow, or brush on bronzer, try makeup artists' two-second trick to give your face staying power: primer. Applied after skincare and before cosmetics, primers keep oil in check and smooth out fine lines so your makeup lasts longer. Our favorites:

• For flawless skin: L'Oreal Studio Secrets Professional Magic Perfecting Base glides on like silk and minimizes imperfections. Your Everywhere editor wears it alone on days she can't be bothered with makeup--and converted her mom and friends to it. Buy here.   
• For sexy eyes: Urban Decay Eye Shadow Primer Potion (pictured) promises crease-free color for up to 24 hours and has a crazy cult following. The original version dries invisibly, or you can opt for three shades that double as highlighters and shadows. Buy here.
• For the multitasker: Miracle Skin Transformer combines primer, SPF 20 and a sheer tint. Choose from seven shades. (See before and after photos here.) Buy here.

It's primer time.
