The invention discloses a method for preparing silk
fibroin and
hyaluronic acid composite gel, which comprises the following steps of: uniformly mixing hyaluronate with a first
solvent to prepare
hyaluronic acid gel, mixing the
hyaluronic acid gel with a silk
fibroin solution, shearing at a high speed, homogenizing and emulsifying, standing, shearing at a high speed, homogenizing and emulsifying, sealing and sterilizing to obtain the silk
fibroin and hyaluronic acid composite gel. According to the method disclosed by the invention, reagents such as a cross-linking agent, an initiator and
enzyme do not need to be additionally added; the silk fibroin solution and the hyaluronic
acid gel can form uniform and mutually-crosslinked double networks in the homogeneous
gel forming process, the phase separation risk is low, and the silk fibroin can generate an
emulsion reaction through high-speed homogenization, so that the color of the composite gel is whiter; the preparation method disclosed by the invention is simple, rapid in emulsification and
gel forming, short in
production cycle, low in endotoxin of the product, high in
biocompatibility, slow in degradation, small in
inflammatory response and high in injection filling safety, and the composite gel can play a role in moisturizing and moisturizing after
subcutaneous injection and has the whitening effects of improving
skin elasticity and glossiness,
fading fine wrinkles and the like.
