Embodiment 1
[0033] Example 1 Preparation of microneedle body fluid
[0034] Dissolve 0.2g of polyvinylpyrrolidone and 1.3g of sodium hyaluronate in 10g of deionized water, stir magnetically until fully dissolved, then weigh 0.15g of palmitoyl hexapeptide-25, 0.05g of acetyl tetrapeptide-3, and 0.1g of three Peptide-2, 0.1g tripeptide-32, 0.1g oligopeptide-1, 0.05g palmitoyl tetrapeptide-10, 0.01g stem cell exosomes, 0.05g arborvitae extract, 0.01g hinokitiol, 0.05g Polygonum multiflorum extract 0.01g β-carotene, 0.01g ginger extract, 0.001g azelaic acid, stir evenly, filter with a 0.22μm aqueous syringe filter to remove excess air bubbles, and obtain the microneedle body fluid.
Embodiment 2
[0037] Example 2 Preparation of Microneedle Base Liquid
[0038] Dissolve 0.5g of polyvinylpyrrolidone, 0.3g of polyvinyl alcohol, 0.6g of sodium hyaluronate, and 0.1g of glycerin in 100g of deionized water, stir until fully dissolved, and filter with a 0.22μm aqueous syringe filter to remove excess air bubbles, namely Obtain microneedle base fluid.
Embodiment 3
[0039] The preparation of embodiment 3 microneedle
[0040] Pour the microneedle body fluids of Example 1 and Comparative Example 1 into two microneedle female molds respectively, and then put the microneedle female molds in a vacuum drying oven at a temperature of 25°C and a vacuum degree of -0.1Mpa After sufficient vacuum injection molding, remove the excess microneedle body liquid on the surface; slowly pour the microneedle base liquid, place the microneedle negative mold in a blast drying oven to fully dry for 24 hours, and demould, respectively to obtain hair growth microneedles and comparative examples Microneedles.
