The most popular and frequently used fillers are made from hyaluronic acid. These allow small, carefully targetted amounts of bulk to be added to the skin in order to backfill wrinkles and lines. They are also used to increase the fullness of lips, cheeks or to alter the appearance of the nose. Fillers can produce a dramatic improvement in appearance within a few minutes and this makes them an attractive choice for many patients.
Hyaluronic acid (HA) is a naturally occurring substance which supports the cells in the skin. It is slowly absorbed by the body after injection and further injections are usually necessary avery 9-12 months in order to maintain an effect. There is a very low incidence of complications or allergy to modern HA fillers.
