Hyaluronic Acid Safety

Hyaluronic acid is a naturally occurring substance in the body, found in highest concentration in the eyes and joints. It has been described as a long, sticky chain of sugar that acts as a lubricant and a cement within the body. It is a major component of synovial fluid within the joints, cartilage, and skin, where it is important for tissue repair. Hyaluronic acid is being tested for an increasing number of conditions, and there are a number of reported side effects.

  1. Medical Uses of Hyaluronic Acid

    • Hyaluronic acid is showing itself to be extremely useful for a variety of uses. It has been used primarily as a treatment for arthritis of the knee, being injected directly into the synovial fluid to act as additional cushioning between the joints. Hyaluronic acid is also being used to add moisture to eye fluid during surgeries for glaucoma and detached retinas. And it is used to encourage skin growth during burn treatment.

    Allergic Reactions to Hyaluronic Acid

    • Hyaluronic acid is not recommended for people with allergies to chicken or chicken products, as it is often made commercially from rooster combs. Allergic reactions can be severe.

    Cosmetic Uses of Hyaluronic Acid

    • Plastic surgeons use hyaluronic acid as filler to plump up wrinkles and depressions in the skin, and to increase fullness in the lips. Because it is a naturally occurring substance in the body, there is less risk of reaction and inflammation. However, a number of side effects with hyaluronic acid injections have been reported, including swelling, bruising, and itching at the site. Some patients report hardness and lumping of the injected material at the site.

    Pre-Injection Safety Requirements

    • Patients taking Aleve, Motrin, vitamin E, and St. John's wort might experience an increase in reactions to injections of hyaluronic acid, so they should stop taking those substances at least a week in advance.

    Oral Use of Hyaluronic Acid

    • Ever since Japanese scientists found a way to make hyaluronic acid into a form that could be absorbed by the intestines, it's been touted as a "fountain of youth" for those hoping to retain their youthful appearance and function. Whether these effects can be achieved through oral hyaluronic acid is still under dispute. Many companies, both online and in print, advertise its benefits. It is available in health-food stores and pharmacies and from online distributors.

    Safety Issues with Oral Hyaluronic Acid

    • Oral hyaluronic acid avoids the problem of tenderness and swelling at the injection site, but there are still reports of rashes and skin irritation while taking the oral form.
