Quench Your Skin
Going from cold, windy air outside to dry heat inside sucks the moisture out of your skin, says N.Y.C. facial plastic surgeon Jennifer Levine, who suggests switching to a heavier moisturizer in the winter (try Olay Definity Night Restorative cream, $25; target.com
). If you're acne prone, look for an oil-free formula (like Philosophy When Hope Is Not Enough hyaluronic acid–peptide capsules, $50; philosophy.com
) loaded with water-binding hyaluronic acid.
