In cosmetics and personal care products, lecithin functions as an emollient, an emulsifier, and as a penetration enhancer.

As an emollient, topically applied lecithin has the ability to soften and soothe the skin. Its high concentration of fatty acids creates a barrier on the skin that effectively seals moisture in while keeping air and other environmental elements out.
