Injectable filler (injectable cosmetic filler, injectable facial filler) is a soft tissue filler injected into the skin to help fill in facial wrinkles, restoring a smoother appearance. It can give you a more youthful look for a fraction of what a traditional facelift costs. Most will fill hollows, lines, and wrinkles in less than 30 minutes with results that can last from 4 months to more than a year.
Injectable wrinkle fillers, unlike Botox injections that relax the muscle under a wrinkle, fill the line, crease, or area with one of several different substances. As a result, trouble spots nearly disappear.
