"I made it my resolution this year to up my vitamin C intake — both on the inside and outside. And while I've made about 1.2 percent progress on the former, the Exuviance AF Vitamin C 20% Serum Capsules ($69) makes it easier for me to live up to my promise on the latter front. Encapsulated in each metallic bead is a highly potent dose of the brightening ingredient — just snap it open, smear it onto your face, and prepare to glow. (No, really, after just a few weeks of use, I've noticed a huge improvement to my skin. My desire to follow through with any of my other resolutions? Er, not so much.)" — KC
