At low concentrations, Propylene Glycol works as a humectant. It holds the water and transports it to your skin's outer layer. It basically aids you in achieving two important goals for your skin: hydration and smoothness. It's especially beneficial if you're frequently dealing with dryness, peeling, or a nasty hard texture. Propylene Glycol is used as a humectant and a conditioner in skincare products. A penetration enhancer is this chemical, which is a frequent ingredient in soaps. This is very effective and economical and safe to use.
