The invention provides a preparation method of facial filling hydrogel for cosmetic plastic surgery, comprising the following steps: S1, preparing modified bioactive glass microspheres; S2, using the modified bioactive glass microspheres to prepare bacterial cellulose coating layer crude bioactive glass microspheres; S3, after sterilizing the crude bacterial cellulose-coated bioactive glass microspheres, to obtain bacterial cellulose-coated bioactive glass microspheres; S4, using the bacterial cellulose coating Layer bioactive glass microspheres to prepare a facial-filled hydrogel pre-canned body; S5, perform negative pressure degassing on the facial-filled hydrogel pre-canned body, then pressurize the canned body into a syringe, sterilize, The facial filling hydrogel for cosmetic plastic surgery is obtained. One of the technical effects of the technical solution provided by the present invention is that the modified bioactive glass microspheres can stimulate collagen regeneration, thereby delaying facial aging. |
