Propylene glycol is a clear, odorless liquid that acts like a moisture magnet, pulling water into the skin to keep it hydrated. It's also commonly used in many everyday products like foods and medications.

This ingredient draws moisture into the skin to improve hydration, conditions and softens skin, helps dissolve other ingredients in formulas, and adjusts product thickness for better texture and application.
