Hyaluronic acid – also known as Hyaluronan, Hyaluronate or HA – is a substance that is naturally found in the human body, where it acts as a cushion and lubricant in the joints and other tissues. In particular, it's present in high concentrations in fluids in the eyes and in the joints.
Hyaluronic acid has multiple beneficial functions, such as hydrating the skin, stimulating the production of collagen in skin, acting as an antioxidant and free radical scavenger, maintaining skin elasticity and cushioning joints and nerve tissues. It also has an antibacterial and anti-inflammatory function and maintains the fluid in the eye tissues.
Just like other protective agents in the body though, naturally occurring Hyaluronic acid levels decrease over time as we age. It is therefore commonly injected as the main active ingredient of filler treatments for cosmetically filling areas of volume loss or eliminating signs of ageing such as facial wrinkles.
Hyaluronic acid fillers are the most common type of dermal fillers. Juvederm and Restylane are common brand names of injectables based on Hyaluronic acid.
Dermal fillers such as Juvederm, Restylane, Hyalronic Acid and Sculptra are very popular, quick injectable treatments that can soften facial wrinkles, lines and fill out hollows to recreate the smooth contours of younger skin. Fillers are popular with those seeking a swift, non-surgical solution for ageing skin that has lost volume as the collagen that previously helped to shape and support it has disappeared.
