Embedded thread clinical application, the most common type of material is PPDO line, usually in the dermis or subcutaneous fascia with needle and thread technology to achieve anti-aging treatment. Its side effects include the following two aspects: 1, material: implanted wire is divided into non-absorbable line and absorbable line two kinds, non-absorbable line appear thread foreign body reaction rate is very small; Absorbable line is more common, its main component is PPDO, non-toxic, harmless, about half a year or so can be decomposed by the human body into carbon dioxide and water. If the material is inferior or impure, it can cause rejection reaction. 2.Surgery: After submerged surgery, facial swelling and slight bruising may occur. 3, the doctor The doctor’s familiarity with facial anatomy and whether the operation is standardized, directly affecting the postoperative effect. For example: pits The shallow implantation of the buried line will lead to large pits on the face, which looks uneven. Small localized pits are normal, but this does not mean that the buried wire has failed. It is not possible to completely avoid the problem of pits when the suspension is strong. It can be recovered in 1~2 weeks if it is fast, or about 1 month if it is slow. Is it good to have the buried threads in the human body? Korea has been conducting in vivo experiments on PPDO material in pig skin for many years. By implanting different sizes of material wires in different parts of pig skin and numbering the corresponding areas, and then biopsying the localized implanted areas of pig skin after different time phases, we have obtained a large amount of valuable data, which provides a reference for the application of PPDO material in human skin. Embedded wire histological characteristics: 1, buried can be completely absorbed and no granuloma hyperplasia, biocompatibility is better, not easy to tissue necrosis or infection. 2.It can effectively promote the regeneration of collagen and elastic fiber to make the skin tighter and more youthful. 3.It can promote the permeability of capillaries, increase tissue nutrition and blood circulation. 4, can effectively improve the activity of fibroblasts, promote the increase of collagen and protein in the skin. Therefore, beauty seekers do not need to worry too much about the wire, provided that the treatment received in a regular hospital.
