"I may never be able to take back the fact that I spent more time in a tanning bed than I did in a library during high school (and, yes, I'm still cringing at the thought), but I'll likely spend the rest of my days fighting the damage it did to my skin. The hardest part has been treating my sun spots and hyperpigmentation, which form deep within the skin and don't give up easily, but the Revision Skincare C+ Correcting Complex 30% ($160) has worked wonders so far. Thanks to its potent blend of vitamin C and E, my spots have visibly brightened." — KC
