Hyaluronic acid is a sugar molecule found naturally in the skin. Prevents the skin from becoming dehydrated by reducing the loss of fluid from the skin. Hyaluronic acids have powerful moisture-binding properties and help regulate the skin's moisture balance by binding the moisture in the skin, so that the skin remains soft and resilient. Moisture and sufficient water are necessary for healthy and fresh skin with a good skin barrier and elasticity. Hyaluronic acid has an effect on signs of aging such as fine lines and wrinkles.
