Beauty lovers have been thinking about what modern means they can resort to in order to fight aging. Ultrasound? Hyaluronic acid? Hyaluronic acid? Botox? Wrinkle reduction surgery? In addition to these, you have a new option – thread lifting, which is the lifting of loose and sagging skin to rejuvenate the face. What kind of wire is buried? There are two main types of threads approved in China: absorbable threads and non-absorbable threads. Absorbable wires are usually used, which are made of PPDO (polypropylene dioxycyclohexanone), and can be naturally degraded and absorbed after being embedded in the skin, so there is no need to remove them. The structure of the wires can be divided into serrated wires and flat slip wires. The serrated wires are used for lifting. The lifting power can be distributed to each small serrated tooth, and even if one of the serrated teeth slips off, there are still other serrated teeth that have a lifting effect, so there is no need to worry about the stability of the effect after the surgery.
