Due to the natural process of aging, the skin gradually loses collagen and fat reserves. It is these components that make up the skin’s skeleton, preventing it from sagging. Dermal fillers help restore the skin to its former youthful appearance. The injection is made into the area where it is necessary to add volume. In modern cosmetology, due to increasing demand for minimally invasive aesthetic procedures, the market for fillers is growing. What are dermal fillers made of? Fillers are classified into the following types.
Capable of rapid resorption
Collagen was the first filler approved as a dermal filler for soft tissue augmentation. Extracted from cow skin, it was subjected to meticulous purification until it became similar to the characteristics of collagen found in human skin. Allergy skin testing is required prior to the procedure, as some people have a positive reaction to animal products.
Collagen-based fillers also vary in density. The most widely used preparation for soft tissue augmentation is hyaluronic acid. It is a natural substance found in the intercellular space of soft tissue. Hyaluronic acid provides the skin with all the necessary components – it is due to hyaluronic acid that the skin is elastic and moisturized. The injected acid replenishes the water balance of the skin, stimulates the production of collagen and elastin, increases elasticity, improves health and improves the overall condition: wrinkles are smoothed out, a lifting effect occurs, i.e. facial contours are lifted. Hyaluronic acid is widely used in general medicine by ophthalmic surgeons to perform cataract surgery, as well as for injections into the joints to restore movement. Fillers differ in terms of hyaluronic acid concentration, degree of stabilization, injection characteristics, ability to lift tissue and manufacturing techniques.
A newer class of fillers, which are characterized by a very long lasting effect in the soft tissues. On the recommendation of specialists, this type of fillers can be prescribed only in individual cases. Despite the lack of a wide range of applications, the product line includes the following types:
- particles in the form of polymethyl methacrylate beads extracted from bovine collagen;
- polymethyl methacrylate particles extracted from hyaluronic acid
- hyaluronic acid with dextran microspheres (polysaccharide of bacterial origin, glucose polymer).
