PEG stands for polyethylene glycol, which is an incredibly useful substance in skincare products due to its vast applications and compatibility with different types of components. It is usually blended with hydrating softeners, beneficial lipids, and cleansing agents. This combination can be used in mild cleansers, high-quality moisturizers, sunscreens, and exclusive treatments.

Recently, the safety of PEG in its diverse forms has been questioned. The primary worry is that they may include potentially damaging impurities like ethylene oxide and 1,4 dioxane, which are byproducts of the manufacturing process rather than something natural to any form of PEG. Fortunately, reliable cosmetic ingredient suppliers have eliminated these impurities from the finished product, thus making PEGs safe to use on the skin.
