"I frequently see women with deeper wrinkles on one side of their face — the side they sleep on, of course," says New York dermatologist Heidi A. Waldorf. To avoid "sleep lines," opt for slippery silk or satin pillowcases and pile on the antiaging products. At night, your body's circadian rhythm naturally lulls skin into repair mode, which peaks between 1 a.m. and 3 a.m., explains Tom Mammone, executive director of R&D for Clinique: "Skin also heats up and gets thirsty in the middle of the night — it opens up, and larger molecules like peptides and vitamin C penetrate better." And like retinol, vitamin C is deactivated by the sun, so night use (accompanied by a moisturizer) is ideal.
