Controllable degradation zinc-based cosmetic line and preparation method thereof

Abstract

The invention relates to the technical field of medical cosmetology, and particularly discloses a controllably degradable zinc-based beauty line and a preparation method thereof.The beauty line comprises a zinc-based beauty line base body and an inorganic magnesium phosphate coating, and the zinc-based beauty line base body is obtained by processing a zinc material; the inorganic magnesium phosphate coating is obtained by carrying out in-situ modification on the zinc-based cosmetic line matrix by magnesium salt and phosphate under an acidic condition; the beauty line obtained by the scheme is excellent in mechanical property, good in heat resistance and corrosion resistance and low in requirements on storage and transportation conditions. The invention further provides a preparation method of the controllably degraded zinc-based cosmetic line, a zinc material is adopted as a raw material, the cosmetic line base body is prepared through the steps of turning, cutting, extruding, drawing, coining and the like, and the zinc-based cosmetic line containing the coating is obtained by partially modifying the zinc-based cosmetic line base body; the beauty line prepared by the preparation method can be controllably degraded and absorbed in a human body, does not need to be taken out by a secondary operation, and is convenient to use and wide in application range.

Description

technical field [0001] The present application relates to the technical field of medical cosmetology, and more particularly, to a zinc-based cosmetic thread with controllable degradation and a preparation method thereof. Background technique [0002] With the improvement of living standards, people pay more and more attention to their external image, and problems such as sagging skin, tissue sagging, and wrinkles have received more and more attention. With the rapid development of the plastic surgery industry, the demand for beauty lines is increasing day by day. The beauty thread researched and developed in recent years, after being embedded in the body surface tissue, can play the effect of lifting the tissue, filling the sunken tissue, reducing wrinkles, adjusting the facial contour and so on. [0003] After the absorbable cosmetic thread achieves cosmetic effect in the tissue, it can disappear through biodegradation, which can avoid the trauma of secondary surgery, so i...

Problems solved by technology

In related technologies, it has been reported in the literature that zinc, as a new type of biomedical material, has good anti-inflammatory properties and promotes collagen production. However, the currently reported zinc-based materials have in vitro cytotoxicity, which is mainly caused by the initial degradation. The local concentration of zinc ions produced is too high, and the in vitro cytotoxicity reaches grade 2-4, which does not meet the requirements of clinical use
