I Won’t Grow Up

W's beauty director uses this moisturizer to keep signs of aging at bay.

“Cellular bioenergetics” is a buzzy scientific term these days. The basic concept: As we age, our cells get tired and lose the ability to repair themselves, leading to everything from obesity to cancer. Skincare experts, of course, are most interested in how this energy depletion affects the face—and what they can do to reverse it. Olay’s answer comes in the form of Regenerist Luminous Tone Perfecting Cream ($34, olay.com), which uses vitamin B3 and dill extract to give skin cells more pep. According to John Oblong, a principal scientist at Procter & Gamble, newly invigorated cells produce healthier collagen and more-even pigmentation, meaning diminished wrinkles and dark spots. Essentially, they act childish—in the best way.
