Embodiment 1
[0038] This embodiment provides a composition for anti-aging, according to parts by weight, the composition comprises:
[0039] 0.1 parts of grape exosomes, 0.1 parts of carnosine, 0.5 parts of glycerin, 0.5 parts of butanediol, 0.1 parts of phenoxyethanol, 93 parts of water;
[0040] The preparation method of the grape exosomes is as follows:
[0041] Weigh 100g of fresh grapes and pour them into a crusher, add 100mL sterilized PBS to it, and after crushing and homogenizing, centrifuge at 3000×g, 4°C for 10min to remove larger residues; , centrifuged at 4°C for 40 min; the supernatant was ultracentrifuged at 120,000×g, 4°C for 60 min, then resuspended in 1 mL of sterile PBS and then ultracentrifuged at 120,000×g, 4°C for 60 min; after centrifugation, washed with 1 mL of sterile PBS Resuspend the pellet to obtain grape exosomes.
