"The fact that the most I've seen of the sun in the last three weeks is through my tiny, 28 x 44" kitchen window has left my skin damn-near translucent, so the need to introduce a little extra vitamin C into my skin-care routine has been a matter of life or zombie. My latest tube of Revision Skincare Vitamin C Lotion 30% ($122) recently bit the dust, so I've been trying my hand at the brand-new Saint Jane The C Drops ($90). It's only been a few days, so I can't say definitively that I've noticed major results, but the luxurious oil feels like a straight-up spa treatment any time I slather it on — and that alone makes it worth using." — KC
