[0092] The preparation method of the above-mentioned liposome with whitening and freckle-removing function comprises the following steps:
[0093] 1) Mix sodium hyaluronate, hydrolyzed collagen and water at 60-70°C to obtain a buffer solution;
[0094] 2) Take a part of the buffer solution, add compound whitening and freckle-removing ingredients, and mix evenly at 40-50°C to obtain the content liquid;
[0095] 3) mixing soybean lecithin and oil evenly at 40-50°C, then evaporating to dryness under reduced pressure to obtain a phospholipid film;
[0096] 4) Take a part of the phospholipid film, add the content liquid, and use the supercritical fluid reverse evaporation method to obtain a monolayer-wrapped liposome;
[0097] 5) Take a part of the buffer solution to disperse the liposomes wrapped in a single layer, add a part of the phospholipid film, and use the film extrusion method to obtain the liposomes wrapped in a double layer, and then repeat the operation to obtain the l...
