Types of Dermal Fillers
The market for injectable fillers has exploded over the last decade; offering numerous options and brands for patients to consider.
A fat transfer is a process that takes fat from one body part and directly transfers it to an area of the face with lost volume. This type of filler offers good results, but may not last as long because the body will naturally absorb some of the injected fat.
Collagen is a protein made up of amino-acids. It can be derived from the human body or animals (known as bovine collagen). Collagen feels very natural when injected. It is commonly used in the lips for lip augmentation.
Calcium hydroxyapatite is a substance found naturally in human bones. It is a mineral-like compound and one of the heavier derma fillers. This particular filler treatment is generally used for deep crevices and creases.
Hyaluronic acid is a natural substance that exists in the human body. It can be found in connective and skin tissue and cartilage. It is extracted, reformulated and then offered as a derma filler. It is a popular choice because of its compatibility.
Polylactic acid is a synthetic substance created and used as a filler. This particular substance works differently than the other fillers because, once injected, it stimulates collagen production. Therefore, results will not be immediate but will appear gradually over time.
The primary semi-permanent filler on the market today is polymethylmethacrylate fillers (PMMA). This filler contains a low concentration of microspheres suspended in a larger amount of purified collagen gel. PMMA is more solid and heavier than most other fillers. It is used for deep wrinkles, deep contours and crevices, and is sometimes used as a permanent implant during reconstructive surgery.
