Hyaluronic acid is a naturally occurring substance found in all connective tissue as well as the viscous fluid that surrounds your joints and eyes. It is responsible for keeping your skin supple and hydrated. Your natural reserve, like so many other things, depletes as you get older, resulting in dry areas of skin, lines, wrinkles, and a lack of firmness. Hyaluronic acid visibly plumps your skin when applied to moisturizers, serums, and even lip plumpers, filling in fine lines and wrinkles and restoring supple smoothness. The following Eminence Organic Skin Care products contain hyaluronic acid from botanical sources.
