Glycerine is found in many moisturizing skin care products and soaps. Glycerine is well-loved as a lotion and soap ingredient because it’s a humectant. A humectant is a substance that pulls water from the second layer of the skin and brings it to the top layer of the skin. If the humidity is high, humectants also draw moisture from the air. As a result, glycerine hydrates skin, helps you shed dead skin cells and gives your skin a smooth, youthful glow
