[0025] 3, the preparation method of above-mentioned fulvic acid is as follows:
[0026] Collect lake water to remove impurities; add the extract at a ratio of 1:10, and the extract is 0.1mol L with a volume ratio of 1:1 -1 Na4P207 and 0.1mol L -1 NaOH mixed solution, shake repeatedly, pass N 2 Continue for 30 minutes; then shake in a constant temperature water bath at 60°C for 15 hours, let stand at room temperature for 2 days, discard the lower layer of sediment; sequentially filter with quantitative filter paper and 0.25 μm filter membrane to obtain the supernatant liquid; the obtained filtrate is adjusted to pH with 1:1 HCl 1-2, in a constant temperature water bath at 70°C for 1 hour, after standing overnight, centrifuge at 3000rpm for 15 minutes, remove the lower layer and precipitate to obtain the crude product of fulvic acid; add the crude product to the dialysate, then place it in a dialysis bag, After dialysis; Freeze and dry to obtain fulvic acid.

Embodiment approach
[0031] The implementation plan is as follows: select 30 people in each group to carry out the experiment. The experimenter used the corresponding product twice a day, and the trial period of each sample was one month. On the 30th day, the experimenter made a self-evaluation of the test effect; and all of them completed the whole experiment, and no other skin care products were allowed during the experiment .
[0032] Trial object: The trial subjects are in good health and are not breast-feeding or pregnant. People who show nasal allergies, white or black spots, and red and swollen noses after heavy metal poisoning.
[0033] Using clinical evaluation of skin quality, trial results: Table 3 below.
