Propylene glycol is a colourless, odourless liquid that is completely water-soluble. Propylene glycol is used as a humectant, a preservative, a solvent, or an emollient in a wide variety of formulas, such as creams, lotions, serums, shampoos, and many other types of personal care products. Propylene glycol has many functions and is used in a multitude of skincare products for its versatility.
It attracts water and boosts other ingredients because of its binding properties. As a humectant, it also offers moisturizing benefits and smooths the skin with a light, non-sticky feel and addresses visible signs of aging. As we age, our skin loses a component called Natural Moisturizing Factor (NMF) and subsequently dries out, which emphasizes wrinkles and contributes to flaking and roughness. Propylene glycol helps bind water from the environment, which assist in counteracting the water loss that accompanies aging. It enhances penetration of active ingredients through the skin, making them more effective. It also helps prevent water loss. It is safe for acne-prone skin because it’s not oily and it helps lessen the appearance of spots over time.
