Hyaluronic acid is a natural substance found in your body. High concentrations are found in soft connective tissues and in the fluid surrounding your eyes. It’s also in some cartilage and joint fluids, as well as skin tissue. It is extracted and reformulated and now has become one of the most popular kinds of injectable fillers.
Hyaluronic acid fillers are a popular choice for reducing the facial lines and wrinkles that result from aging. Such fillers are made from hyaluronic acid, a substance found naturally in the body’s connective tissues and skin. Once injected, they plump up facial skin that may have lost volume or elasticity as part of the aging process, filling in wrinkles from the inside and making the skin appear younger and rejuvenated.
Over the past few decades, many types of hyaluronic acid fillers have been developed. Brand names of HA fillers include Juvederm family Fron Allergan : Juviderm Ultra, Voluma, Vollbellar, Restylane family from Galderma: Resteline, Restylane lift, Restylsne Silk, Refine, Define, Belatero from Merz. A few are meant for deeper facial folds, while others are intended for more superficial wrinkles.
Injections of HA-based fillers are performed while patients sit in a chair in the doctor’s office. The treatment takes an hour or less; many people call the use of injectable fillers a ‘lunchtime facelift’ because of the short time needed for treatment.
Some formulations contain lidocaine, a local anesthetic. In other cases, the doctor will administer a topical or local anesthetic in order to make treatment as comfortable as possible. Then, the chosen filler is injected through a thin needle into the targeted area of skin. The exact volume of HA filler injected depends on the depth of the wrinkle, amount of change desired, skin type, and other factors. After injection, the skin may be massaged in order to smooth the injected material and ensure the most aesthetically pleasing and natural-looking results.
