Injection of cosmetic micro-plastic surgery is simple, safe, less injury, less pain, quick recovery and remarkable effect. In recent years, with the joint efforts of biologists, materials scientists and medical scientists, injection cosmetology has made great progress. Because of its simple operation, quick recovery and little pain, injection cosmetology is called "quick cosmetology" and "lunch break cosmetology" abroad.

Injection cosmetology is the application of synthetic or extracted human absorbable substances, which are filled into subcutaneous tissue through injection therapy to improve the state of wrinkles or tissue defects, thus achieving the purpose of cosmetology. Different brands and different substances have different maintenance time after injection.

1) Wrinkles: Age, smoking, squeezing while sleeping, and gravitational traction will all reduce collagen and elastic fibers in the dermis, causing skin relaxation and facial wrinkles.

2) Lip shape: The lips will shrink with age, wrinkles will appear, and the corners of the mouth will droop with age.

3) Face shape: Aging will change the distribution of subcutaneous tissue, with sunken temples, cheeks, eyes and lips, and redundant sagging on both sides of chin and nasolabial groove.

4) Notch of muscle movement: One third of wrinkles on the face often come from muscle movement, but after a long time, it will cause deep static dents.

5) Modification of volume: height of nose, shape of nostril, size of earlobe, shape of lips, etc. It can be adjusted according to different people, and the congenital face contour can also be easily changed by filling.

6) Filling of defects: Pockets, scars caused by trauma and surgery, and asymmetry of congenital defects can all be reconstructed by filling.
