collagen was the first filler injected to augment the
face. Over 1.5 million
soft tissue filler procedures were performed in the United
States in 2007; hyaluronic acid (HA) is the most frequently used
agent. In fact, HA has become the most commonly used filler
worldwide. Not all injections are created equal, however, and no
filler is ideal, nor can a single filler meet every patient's wishes

calcium hydroxylapatite, which restores facial volume and promotes collagen
production. The filler, also known as Radiesse, is thicker than the
hyaluronic acid fillers currently available and the results last longer – up
to a year in most cases. It is composed of calcium based microspheres
suspended in a water based gel
How dermal fillers works?
Dermal filler is a nonsurgical treatment. The patient
should be in a relaxed and generally supine position. The filler is
injected under the skin using a fine needle to smooth away lines,
restore natural contours and enhance lips for a smooth, natural and
refreshed appearance. Filler can be injected by one of the
following 4 techniques: serial puncture, threading, fanning, and
crosshatching. Each technique has advantages for certain situations,
and the ultimate determining factor is often surgeon preference.
To begin with the doctor will examine the soft tissue of your face
to assess the depth of
wrinkles and folds and determine your treatment. He might ask to
take pre-treatment photographs so you can see the difference after
treatment! Although anesthesia is not required, some doctors might
suggest use of topical anesthesia to numb the treatment area first.
Following the injection, they may gently massage the treated areas.
The procedure is quick and easy. The injection itself typically
takes 15-30 minutes.

wrinkle smoothing or volume enhancement, and results may last up to
