There are three types of commonly used fillers:
Collagen-based fillers: Collagen is a naturally occurring protein that contributes to the strength and structure of the skin. Collagen was the first filler on the market, but the arrival of hyaluronic acid-based fillers has reduced its popularity.
The hyaluronic acid-based fillers such as collagen, hyaluronic acid is a naturally occurring substance, and used primarily to promote fullness and volume.
Calcium hydroxyapatite: Heavier and denser than hyaluronic acid, this filler is injected deep under the skin and usually not immune or allergic reactions occur, because the material is usually found in the bones.
Longer-lasting dermal fillers typically contain thicker substances, such as the biodegradable synthetic filler, known as poly-L-lactic acid. These types of soft tissue fillers are used to treat deep wrinkles on the face, although they offer semi-permanent results, it is possible that you need an occasional “retouch” several weeks after the first injection.
Permanent fillers are made of polymethyl methacrylate (PMMA), with microspheres, which are not absorbed by the body. The filler also contains collagen and is recommended only for the pachyderm parts such as the nasolabial folds. It is not recommended for all areas around the eyes or lips.
