🍒 Many conventional cleansers contain powerful detergents (aka surfactants) that—just as they break up oil spills on roadway or grease on a frying pan—strip away the natural, beneficial oils on your skin. Cosmetic companies’ solutions tend to involve adding back in moisturizer once you’ve cleansed, a strategy akin to substituting vitamins for whole foods. Instead, think of moisture like a healthy supplement, not the main event, and think of proper skincare, in large part, as an effort to maintain the natural oils you’ve got on skin. -Goop
