"In the winter, L.A. women need to be sure that they are using a low-foaming, gentle, sulfate-free cleanser to wash their skin. This means using a cleanser free of sodium lauryl sulfate or ammonium laureth sulfate. These are commonly used detergents in cleansers that can strip moisture and dehydrate the skin. In winter, it's all about keeping moisture in the skin, so making sure to use a cleanser that won't unnecessarily dry out the skin is important."
