Quick fix: Overcleansing dries out your skin, so be sure to choose a mild formula. "You need to preserve your skin's protective oils in the winter, not wash them away," says Susan Van Dyke, MD, a dermatologist in Paradise Valley, Arizona.
Seasonal solution: "If it's time to get out your winter coat, it's time to switch to heavier, more protective skincare products," says Brooke Jackson, MD, dermatologist and founder of the Skin Wellness Center of Chicago. After cleansing in the morning, apply a moisturizing serum with hyaluronic acid (a potent hydrator) and use a face and eye cream. It's important to make sure both contain UV protection. Before bed, rub in a layer of rich night cream.
