Moisturizers use two types of hydrating ingredients: humectants, which attract water molecules to the skin, and emollients, which seal that moisture on top by forming an occlusive protective barrier. There are usually plenty of both in a single moisturizer, and many humectant and emollient substances are multitaskers used to make the vehicle more effective. Their primary function may be to make the lotion creamier or better able to glide onto the skin, but they also have a secondary hydrating benefit.
