What types of facial fillers exist?

Fillers are organic and synthetic substances that are implanted by intradermal injections to correct the effects of age and give volume to certain facial areas.

There is a wide variety of products, each one of them with its own characteristics and an applicability that must be known precisely: some of them have a more volumizing effect, others a more tightening effect, etc. In a very simplified way, we can classify the fillings as follows:

According to its duration in the fabric

Temporary (autologous fat, hyaluronic acid and collagen), semi-permanent (calcium hydroxyapatite and polylactic acid) and permanent (polyacrylamide gel, polymethylmethacrylates and silicone). Resorbable fillers, due to their better safety profile, are the most widely used.

According to its composition

Autologous fat from the patient, collagen (bovine, porcine and human), hyaluronic acid, polylactic acid, calcium hydroxyapatite, polymethylmethacrylates and polyacrylamide gels.

According to its degree of crosslinking

It consists of a chemical modification of the products (especially applicable to hyaluronic acid) to achieve a three-dimensional network of polymers, making the substance more rigid. Thus, the natural hyaluronic acid will be more fluid and volatile, while the greater the crosslinking, the greater thickness and durability will be achieved.

The indication of the product in its natural or cross-linked form will vary depending on the effect we want to achieve: for a hydration or volume effect, non-cross-linked hyaluronic acid is used, which stimulates the fibroblast and the injection is performed at a shallow depth; For a tightening and filling effect, instead, cross-linked hyaluronic acid is used to correct wrinkles and lack of volume, injecting it deeper (in the middle dermis, deep dermis, or subcutaneously).
