Considering that you literally come face to face with the elements every day, it’s no wonder that your cheeks wind up red and dry. They are, after all, outside of the oilier “T-zone” (forehead, nose, chin) and are therefore less protected from moisture-sapping cold air, low humidity and wind. Keep cheeks hydrated by using a moisturizer that contains glycerin, which acts as both a humectant , attracting moisture to the skin, and a barrier against the elements, says Ellen Marmur, M.D., chief of dermatologic and cosmetic surgery at the Mount Sinai Medical Center in New York City and author of Simple Skin Beauty. If you’re battling super-dry skin, look for a souped-up moisturizer -- one containing shea butter, squalane, lanolin, mineral oil or combinations of these ingredients. If you’re acne-prone, use a noncomedogenic moisturizer such as Cetaphil, CeraVe or Vanicream to replenish moisture without clogging pores.
