Fillers are basically the volume-adding biocompatible particles, mainly composed of hyaluronic acid. They are used to improve static wrinkles and folds, like nasolabial folds, glabellar lines, neck folds, accordion lines (smile lines). They even help to increase volume in lip augmentation (enhancement or development), lip wrinkles, cheek augmentation and eye circles and work for the rejuvenation of hands and neck parts; and, at times, they work for the improvement of deformed features, like asymmetry of nose or scar correction. Very fine needles are used to reduce pain sensations and to inject the filler particles to add volume to the desired parts. Nowadays, blunt canulas are also used which cut down the pain significantly. For more sensitive clients, nerve blocks can be given to reduce the painful sensations.
