This product will help to support the skin’s ability to replenish its own HA (hyaluronic acid). This products combination of 5 HA forms will smooth the skin, and therefore decrease the appearance of fine lines and wrinkles. You will see continuous hydration for up to 8 hours. Apply to face, neck and décolleté, or any area where fine lines and wrinkles exist. Because HA5 is a "water-loving" substance, wet your fingertips prior to applying HA5 to your skin.
