Example Embodiment
[0027] Example 1
[0028] Weigh 15 parts of lecithin and 85 parts of soybean phospholipids by weight in a mixture of chloroform and methanol (v:v=1:1), add 30 parts of jojoba oil, 25 parts of vitamin E, 20 parts Parts of superoxide dismutase and 10 parts of dipalmitoyl hydroxyproline were evaporated under reduced pressure to remove the organic solvent to form a thin film. Add a phosphate buffer solution with a pH of 6.5 and a concentration of 8mmol / L, mechanically stir and hydrate for 3h at a temperature of 50°C to obtain a suspension and stand for 24h, and centrifuge to obtain liposome A. Weigh 45 parts of sphingomyelin, 15 parts of cholesterol, 15 parts of fatty acids, 15 parts of phosphatidylcholine and 10 parts of cholesterol sulfate in a mixture of chloroform and methanol (v:v=1:1) Add 10 parts of glutathione, 25 parts of fruit acid, 35 parts of vitamin C, 10 parts of retinol, 5 parts of coenzyme Q10, and evaporate the organic solvent under reduced pressure to form a thin f...

[0029] Example 2
[0030] Weigh 15 parts of lecithin and 85 parts of soybean phospholipids by weight in a mixture of chloroform and methanol (v:v=1:1), add 40 parts of jojoba oil, 30 parts of vitamin E, 30 parts Parts of superoxide dismutase and 20 parts of dipalmitoyl hydroxyproline were evaporated under reduced pressure to remove the organic solvent to form a thin film. A phosphate buffer solution with a pH of 6.5 and a concentration of 8 mmol / L was added, and the suspension was mechanically stirred and hydrated for 3 hours at a temperature of 45° C. to obtain a suspension and allowed to stand for 24 hours. After centrifugation, liposome A was obtained. Weigh 45 parts of sphingomyelin, 15 parts of cholesterol, 15 parts of fatty acids, 15 parts of phosphatidylcholine and 10 parts of cholesterol sulfate dissolved in chloroform and methanol (v:v=1:1) In the mixed solution, 15 parts of glutathione, 30 parts of fruit acid, 45 parts of vitamin C, 10 parts of retinol, and 10 parts of...
