Remember those clear mood lip glosses from your pre-teen years that changed color when you put them on? These blushes have been developed based on a similar premise. They start off as clear gels and once applied to your cheeks they adjust according to your specific skin tone - how fab!

Smashbox O-Glow, $26, is formulated to change color on your face to the same natural tone as when you blush. Wow, talk about a natural look!

It takes just seconds for its chemistry to work. When applied, the moisture on your skin activates the Goji Berry-C Complex™ ingredient and your circulation gets going. This results in a fresh looking flush that lasts all day long. This gel blush is waterproof, fragrance free and won't irritate your skin.
