Hyaluronic acid is a natural substance found in the human body. It is present in high concentrations in soft connective tissues, the fluid surrounding the eyes, some cartilage, synovial fluid, and the skin. It is extracted, processed, and used, making it one of today’s most popular injectable materials. The hyaluronic acid used in plastic surgery is the same material injected into painful joints of arthritis patients to alleviate pain and improve the problematic joint. Patients should be aware that hyaluronic acid is not produced from animal sources, and the most well-known brands used are Juvederm, Restylane, and Perlane.
When hyaluronic acid is injected into the human body, it acts as a substrate that supports facial structures and tissues that have lost their volume or elasticity due to natural aging. At the same time, it binds water to the skin’s surface, helping the skin stay fresh and elastic.
There are various densities of hyaluronic acid, each serving different areas of the face. These include nasolabial folds, perioral wrinkles (smoker’s lines), marionette lines, and various other facial deficits. Hyaluronic acid is also used for lip augmentation. The application requires the use of a topical anesthetic cream to eliminate or significantly reduce pain during injection. After the application, there is a possibility of some bruising and moderate swelling, which can be covered with makeup. The results of hyaluronic acid last 9-12 months.
