A signature beauty look gives you confidence from the inside out. It's the style that makes you feel — and look — your best. And it's what we at Refinery29 often dub a "power face."

"I love looking like you just had a really hot and heavy makeout session," she says of a naturally flushed look. "Or that feeling like, I have a secret. It makes you feel sexy and strong."
