Types of Injectable Fillers

The injectable filler is a common cosmetic procedure in cosmetic clinics around the world, though surprisingly this style of cosmetic treatment is not even close to being new just far more advanced and refined thanks to advances in science and medical knowledge. Starting around the year 1900 surgeons would add more volume to various facial regions by using paraffin wax injections which seems very crude compared to today’s more commonly used methods. For those seeking a more youthful look or recovering more of their youthful appearance, things have come a very long way since then. There are many types of dermal filler available today which will be somewhat broken down into common types below.

Collagen Fillers: 

Collagen fillers have been around for around 35 years now. The majority of skin tissue is made of a protein called collagen. A form of collagen can be derived and purified from bovine (cows). When injected into soft tissue it will typically last around three months before being absorbed and processed by the body. Collagen fillers are far less prevalent today and barely used and almost entirely replaced by hyaluronic acid based fillers. Hyaluronic acid (HA) is a natural carbohydrate found in our skin and cartilage and various other parts of our body. When HA is combined with water, it will swell into a gel-like substance. It is commonly derived from bacteria but also rooster combs. In recent years, HA fillers improved to last quite a bit longer before absorption becomes apparent typically 6-12 months. HA-based fillers are quite popular and used extensively by our Cosmetic Doctors at Skin Club in Melbourne, Chapel St. Calcium hydroxylapatite is one of the minerals found in bones and teeth, particles of calcium hydroxyl can be suspended in a water-based solution with a gel-like consistency in order to inject. This type of filler can last as long as 12 months. This type is best suited to specific areas of the face such as cheekbones.

PMMA & PLLA Fillers: 

For years in the medical field, it has been used in absorbable stitches and bone screws. PLLA fillers while lasting two years are injected over a series of months. Polymethylmethacrylate (PMMA microspheres) is a polymer that is man-made that is sometimes used as a filler. It has been used rather extensively as bone cement in surgical procedures. 80% collagen mixed with 20% PMMA microspheres are combined into a gel-like consistency to form a filler for injection. After some time the microspheres break down, but our body produces its own collagen to fill in the spaces left behind. PMMA fillers take several sessions necessary to create the required volume and can take around three months to proper results. Platelet-rich fibrin matrix (PRFM) fillers use a patient’s own platelets that are then reinjected into areas that result in stimulation of collagen production. When this filler is injected clotting occurs that forms the framework for this area to fill. PRP is best utilized in areas where there has been discoloration or scarring. However, the best results are seen in the face where there are significant amounts of nutrients available for our cells to grow and reproduce growth factors, stem cells and collagen

At Skin Club we are using one of the highest concentrations of PRP in Melbourne, Australia to target acne scars, stimulate hair follicle growth for male balding and joint injections. If you are interested in PRP injections, contact us and book a consultation.
