Why does it seem like wintertime is nearly synonymous with ashy, scaly legs? “The further you go away from your heart, the less efficient the return of blood,” says Day. The process can leave our skin depleted of moisture and the effect is exaggerated in the winter when the cold weather inhibits circulation. As the days get colder, Day suggests swapping out your normal lotion for a moisturizing cream or ointment. Lotion, which is water-based, is fine in the summer when your skin can draw moisture naturally from the water in the air. But during the winter, a cream -- which is oil-based -- will both protect and hydrate your skin, and you won’t lose that moisture to evaporation. Moisturize often, especially after showering.
