10 Ingredients to Look For in Your Winter Skin Care, According to the Experts

"In Winter months, you'll want to look for smoothing ingredients that reduce skin roughness and conform to the skin contours, filling in fractures and fissures. Silicones are among the most active and have a semiocclusive effect. They remain on the surface of the skin, forming a permeable barrier. Among them are dimethicone and polysiloxanes, which have conditioning properties and are safe to use on the skin." — Thornfeldt
