The types of injection fillers are not only classified according to the maintenance time, but also according to their functions. In addition to the hyaluronic acid introduced, which can absorb water to fill the depression, there are also polylactic acid polymers (PLLA) that have been used in the market many years ago
What polylactic acid PLLA?
Poly (L-lactic acid) PLLA is a kind of artificial material that is compatible with the human body and can be decomposed. It has been used as absorbable suture by the medical profession for many years. Therefore, it is extremely safe for the human body. It is used for facial injection to supplement lost collagen. It has been used to fill the cheeks of HIV-positive patients with thin face since 2004, and was approved by the US Food and Drug Administration to treat mouth wrinkles in 2009.
Role of polylevolactic acid
The collagen in the skin is the main structure that keeps the skin young and elastic. The age of the year is getting longer, the collagen in the body is gradually lost, and wrinkles are produced. Molanya – polylevolactic acid is injected into the deep part of the skin to stimulate the production of autogenous collagen. After an injection course, it can replenish a large amount of lost collagen, fill the sunken part, improve the facial wrinkles and pits from shallow to deep, and maintain a more delicate and youthful appearance of the face.
The biggest difference between polylevolactic acid and other fillers is that in addition to directly stimulating the production of bone collagen, the effect of polylevolactic acid is slowly emerging after a course of treatment, and will not be seen immediately. A course of treatment of polylevolactic acid can last for more than two years.
Polylevolactic acid is most suitable for those who feel that the sudden change will be too obvious, and want to improve gradually. After the improvement, people around you will only feel that you are getting younger and younger in a few months, but they will not notice what surgery you have done.
