Restylane
Restylane is a sterile gel of non-animal stablised hyaluronic acid for injection into the skin to correct facial lines, wrinkles and folds, for lip enhancement and for shaping the facial contours. Because it is a non-animal product no testing is required prior to use. This is one of the safest fillers and has been in prescribable use since its introduction from Sweden in 1996. It has full FDA approval for injection of wrinkles since 2003

CRM (Matridur/ Matridex)
Matridur is a mixture of non- animal stabilised hyaluronic acid and cross-linked hyaluronic. With Matridur, the hyaluronic acid is completely broken down within the skin over a period of months, eventually leaving no trace of the filler. With Matridex, although the hyaluronic acid is broken down, the microspheres remain to form a stable and permanent implant. It was introduced from Germany to Ireland and the U.K. in 2004

Sculptra (New Fill)
New-Fill poly-L-lactic acid is a collagen stimulator which works from deep within to stimulate new collagen to smooth and firm areas of the face and restore the skins natural elasticity. This compound, although recently used in cosmetic medecine has been used in plastic and reconstructive medecine in Europe for more than 20 years. Clinical trials have shown the effects of New-Fill can last for 1 to 2 years. It is undergoing FDA approval.

Radiesse

Radiesse is a suspension of calcium hydroxyapatite (CaHA) particles in glycerin and saline. Once injected just below the dermis, the glycerin carrier is absorbed, and a fibrous layer is deposited around the CaHA particles, stabilizing the implants and adding further bulk. The clinical effect of Radiesse is estimated to be between 2 and 4 years. Radiesse is currently approved by the FDA in the U.S. for vocal fold augmentation.

Bio-Alcamid
Bio-Alcamid is a prosthetic implant of composed of 97% water and a synthetic polymer. It is designed to fill bigger areas like scars, lips, deep wrinkles and sunken cheeks. Think of this Italian product as a permanent replacement for fat tissues. If you have a reaction, the company claims that it is possible to incise the skin and take the compound out. There is evidence that a physician can also dissolve the implant with an injection of H202 (hydrogen peroxide) but we are unaware of any proceduralist that does this on a regular basis.
