Embodiment 1

[0013] figure 1 A laser-based process for activatable medical dermal injectable fillers. In this embodiment, two kinds of particles are mixed, but more kinds of particles can be mixed in the implementation process of the present invention. The more types are added, the better the prolongation effect of the filler is, as long as the laser that can completely crush the corresponding wavelength of each particle is used You can.

[0014] (1) Two kinds of special particles (triangular particles and square particles) are mixed into the cross-linked hyaluronic acid filler. It will not be phagocytized and digested by phagocytes in the dermal tissue and transported to the local lymph nodes, and it will not be too large to affect the viscosity and viscoelasticity of the filler. In addition, the two kinds of particles have different light absorption characteristics, and can be completely crushed under the action of laser light with the corresponding absorption peak wavelength. Among th...

Abstract

The invention discloses an activatable medical percutaneous injection filler based on laser, which mainly comprises crosslinked hyaluronic acid, and a special particle component with good tissue compatibility, wherein special particles are mixed into the crosslinked hyaluronic acid filler, and are 50-100 micrometers in particle size. The action time of the filler by single injection can be prolonged to be multiple times than before by the action of the laser.

Description

technical field [0001] The present invention relates to a medical filler, and more particularly to a laser-activatable dermal injectable filler. Background technique [0002] Injectable fillers are currently one of the most commonly used non-invasive treatment methods in the field of international dermatology. As well as expanding tissue volume to make it plump (such as lip augmentation or nose augmentation), etc., injectable filling has become the fastest growing item in the field of beauty in recent years. There are many types of medical injectable fillers, including collagen, hyaluronic acid, gelatin, silica gel, and autologous fat. However, hyaluronic acid has excellent tissue compatibility, almost no sensitization and good viscoelasticity, and has gradually become the material of choice for dermal injection fillers. Hyaluronic acid (Hyaluromic acid, HA) is a linear polysaccharide component widely present in the extracellular matrix of animals naturally. Consisting of...
