THXSILK Hyaluronic Acid Double Hydration 22 Momme Silk Face Beauty Mask
What is HA?
Hyaluronic acid (HA) is a substance found naturally in our skin that holds water and helps keep it hydrated and plump. The molecule holds a thousand times its weight in water to not only retain all that moisture in our skin, but also prevent all that moisture from evaporating into the air. When used in skincare products like creams and serums, hyaluronic acid hydrates and soothes dry skin.
