Few skin care ingredients have gotten more recent press than hyaluronic acid. What is hyaluronic acid? This substance is produced by the body to keep eyes, skin and connective tissue hydrated by retaining water. Although the amount of hyaluronic acid (HA) is naturally depleted as we age, products and supplements with this active ingredient boast a range of health and beauty benefits.
Healthy, Youthful Complexion
One of the most talked-about hyaluronic acid benefits is its ability to smooth skin, improve the appearance of fine lines and wrinkles and create a softer, more supple texture. Taking up to 240 milligrams as an oral supplement has been clinically shown to improve dry skin, while other research has found that topical HA helps soothe dermatitis and redness while smoothing facial lines.
Treatment For Dry Eyes
Because HA helps the body retain water, it can add moisture to dry, itchy, uncomfortable eyes. In clinical trials, the dry eye symptoms that affect one in seven U.S. adults are relieved with drops containing 0.2–0.4% hyaluronic acid. These drops are also used by eye surgeons to promote healing and reduce inflammation during procedures.
Relief From Joint Pain
HA supplements are often prescribed for individuals with osteoarthritis. Because this condition is caused by wear and tear, increasing the body's natural hyaluronic acid will lubricate the joints and prevent the pain and discomfort that occurs when bones rub together. Clinical studies have shown this is especially effective for those with knee pain caused by osteoarthritis between ages 40 and 70. The recommended dosage is 80 to 200 milligrams.
When applied to damaged skin, HA expedites healing by promoting new blood vessel growth in the injured area. It also relieves pain by reducing inflammation and can help prevent infection when used topically.
