Problems solved by technology

[0003] Currently commonly used dermal fillers are mainly composed of synthetic hydroxyapatite, polylactic acid microspheres, polymethyl methacrylate microspheres and other microspheres. These dermal fillers have a long service life and good stability. However, Studies have shown that such dermal fillers have poor biocompatibility and are prone to granuloma formation
[0004] The existing collagen filler products in the domestic market include cross-linked collagen fillers and non-cross-linked collagen fillers. However, the residual cross-linking agent will cause toxic and side effects on the skin and cause a series of adverse reactions. Moreover, the main components of the existing collagen filler products on the market are collagen, anesthetic, cross-linking agent, and buffered saline solution, and the ingredients are single. The use effect is single, and a small amount of water will be separated out after being refrigerated for a long time, and the stability of the product is poor

Abstract

The invention discloses a composite multi-component collagen micro-emulsion filler and a preparation method thereof. The composite multi-component collagen micro-emulsion filler is a multi-component composite micro-emulsion filler based on collagen, and a vacuum heating physical cross-linking means is adopted to physically cross-link type I collagen, type III collagen and hyaluronic acid, mechanical property of the collagen is improved, degradation time of the filler is prolonged, and good biocompatibility of the collagen is fully exerted.

Description

technical field [0001] The invention relates to a composite multi-component collagen microemulsion filler and a preparation method thereof, belonging to the field of medical cosmetology. Background technique [0002] The facial skin tissue of the human body is maintained by proteins such as collagen and elastin and an extracellular matrix containing mucopolysaccharides. When soft tissue loss occurs due to reasons such as congenital, external impact, or disease, dermal fillers containing ingredients similar to skin tissue can be injected into a specific site to restore the soft tissue or correct its shape. [0003] Currently commonly used dermal fillers are mainly composed of synthetic hydroxyapatite, polylactic acid microspheres, polymethyl methacrylate microspheres and other microspheres. These dermal fillers have a long service life and good stability. However, Studies have shown that such dermal fillers have poor biocompatibility and are prone to granuloma formation. ...
