Hyaluronic acid (HA), is a naturally occurring polymer in every tissue of the body, such as skin and inside joints. HA is important to retain collagen, increase moisture, and provide elasticity and flexibility in your skin, helping to stave off physical signs of aging in the face.
As with many other biochemicals our body manufactures, our stores of HA tend to dwindle as we age. Your skin starts losing hyaluronic acid as early as age 18, but wrinkles and other skin damage from slowed production of HA don’t generally begin to be noticeable until the late 30s or early 40s. Preserving or regaining hyaluronic acid is a goal of many skin care scientists and products that can help with these tasks can keep skin supple and youthful-looking.
In the joints, HA helps provide the lubrication known as synovial fluid, which allows for the smooth movement and range of motion. In fact, physicians inject HA into the joints in those who have arthritis, so HA is safe and effective!
