Hyaluronic Acid, also known as “HA”, is critical to reduce the visibility of fine lines and maintain elasticity of our skin. It is naturally occurring molecule found throughout almost every fluid and tissue in our bodies, primarily in the skin, eyes, and joints. Your skin cells also can produce hyaluronic acid daily in order to maintain moisture levels. However, due to the pesky aging and environmental aggressors, those levels tend to take a bit of a dip. HA plays an important role in maintaining skin hydration aimed to stop aging.
