Well-defined plump lips, donated by nature, adorn a woman's appearance and attract attention. But if nature was not so generous to you, you can correct the shape and size of the lips with the help of corrective plastics. It is carried out on the basis of special preparations called fillers.
A filler is an injectable biodegradable implant that makes it possible to perform contour plastic without surgical invasion. Injection preparations allow you to adjust the shape and volume of the lips. Also, with the help of fillers, the following goals are achieved:
- Raising the corners of the lips;
- Correction of the lip shape;
- Increase in natural volume;
- Smoothing fine wrinkles.
Implant injections are carried out with a syringe with a very fine needle. The duration of the procedure is from a quarter to half an hour (depending on the experience of the cosmetologist performing it). The procedure itself is quite painful since the tissues of the lips contain many nerve endings. To minimize discomfort, manufacturers often include an anesthetic in their fillers.
In the classification of injectable preparations-implants, first of all, biodegradable fillers based on synthesized hyaluronate of artificial or animal origin are distinguished. These funds are based on hyaluronic acid - non-sulfonated glycosaminoglycan, which is part of the connective, epithelial, and nervous tissues. It is the main component of the extracellular matrix of biological fluids.
Biodegradable hyaluronic acid fillers are divided into the following types:
- Monophasic - hyaluronate contained in the preparation has molecules of the same size. This gives the active substance greater plasticity and facilitates its application;
- Biphasic - hyaluronic acid of this type has different molecular weights;
- Collagen preparations made from porcine, bovine, or human fibrillar protein;
- Patient tissue obtained by autologous transplantation. In other words, the transplant recipient is his own donor;
- Polylactic acid implants.
Another type of filler is synthetic materials based on polymer gel. They are classified as non-biodegradable and are classified as follows:
- Sodium triphosphate;
- A biosynthetic filler based on synthetic poly L lactic acid isolated from human tissue.
Another type that needs to be mentioned: synthetic fillers, which contain polymethyl methacrylate in collagen, which acts as a transported material. This type of filler is prohibited in the United States and many EU countries due to the potential harm, as well as the risk of complications and side effects after the procedure.
