Lecithin is a phospholipid most often derived from soy and functions as an emollient and water-binding agent with skin-restoring abilities.
Lecithin is a yellow-brownish fatty substance that naturally occurs in plant and animal tissues, as well as in the human body. It’s made up of fatty acids linked to the choline ester of phosphoric acid. Lecithin fats are amphiphilic, which means they attract both water and oil substances (it acts as a water-in-oil emulsifier).
As an emollient, topically applied lecithin has the ability to soften and soothe the skin. It effectively seals moisture in while keeping air and other environmental elements out. This property makes it excellent for mature, dry, or compromised skin.
Lecithin is also used in liposomal encapsulation to help stabilize sensitive active ingredients and facilitate their delivery.
