Hyaluronic acid (HA) is a natural substance found in all human skin. Thus, hyaluronic acid (HA) injections are biocompatible (does not harm the body) and biodegradable (broken down by the body). HA does not require testing for allergies. Examples of available HA skin implants are Restylane, Perlane, Juvederm, Hyalaform, and Teosyal. These products are injected into the skin or deeper tissues to help correct skin depressions such as creases, wrinkles, folds, scars, degenerative skin aging, and restore lost facial volume due to facial lipoatrophy (loss of fat).
In our experience, patients that undergo multiple treatments have the best, most satisfying results. The effect of HA treatment may last from 6 months to 2 years, but this time frame varies from person to person.
There are a few risks with any treatment. The vast majority of individuals have no problems. A local anesthetic injection may be offered to reduce any pain or discomfort with the procedure. The possibility of short term after effects include: some redness, swelling, discomfort, bruising, itching, and tenderness at the injection site.
