Obagi Nu-Gen Cellular Renewal Serum ($175)

"NAD+ is very buzzy right now, and the Obagi Nu-Gen Cellular Renewal Serum is the brand's response to that trend in skin care. It targets major signs of aging — uneven skin tone, sagging, fine lines, dullness, redness, and dehydration — in one powerful formula. The texture is so light and fast-absorbing, and layers beautifully with my other products." — Jessica Harrington, Section Lead, Beauty
