Silk fibroin skin-beautifying gel and preparation method thereof

The invention discloses silk fibroin skin beautifying gel and a preparation method thereof. The composition is prepared from the following raw materials in parts by weight: 5%-8% of a silk fibroin nano-emulsion, 0.3%-1.0% of a thickening agent, 0.1%-0.5% of an amine auxiliary agent, 0.1%-0.5% of probiotics, 5.0%-10.0% of proteoglycan, 2.0%-3.0% of prebiotics, 0.1%-0.25% of a humectant sodium hyaluronate, 0.5%-1% of nano-silver ions, 0.3%-1.0% of an accelerant, 0.3%-0.5% of anti-allergic agent essential oil, and the balance of pure water as balance. The silk fibroin nano-emulsion is hydrolyzedto generate silk peptide, so that the effect of inhibiting generation of skin melanin can be achieved; pro-xylane can promote generation and construction of protein polysaccharide in an extracellularmatrix, and maintain tenderness and compactness of the skin; in addition, the pH value of the private part can be synergistically adjusted by a lactobacillus and chlorella extract/lactic acid mixture;sodium hyaluronate can ret
