[0028] 3, the preparation method of above-mentioned fulvic acid is as follows:
[0029] Collect lake water and remove impurities; add the extract according to the ratio of 1:10, the extract is a mixture of 0.1mol L-1Na4P207 and 0.1mol L-1NaOH with a volume ratio of 1:1, shake repeatedly, and pass N2 for 30min Then shake in a constant temperature water bath at 60°C for 15 hours, let stand at room temperature for 2 days, and discard the lower layer of sediment; sequentially filter with quantitative filter paper and 0.25 μm filter membrane to obtain the supernatant liquid; the resulting filtrate is adjusted to pH 1-1 with 1:1 HCl 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, and dialyze it in deionized water ; Freeze, dry, get fulvic acid.

Embodiment approach
[0035] The implementation plan is as follows: select 30 people in each group to carry out the experiment. The trial period for each sample is one month, and all participants have completed the entire experiment, and no other skin care products are allowed during the experiment.
[0036] Trial objects: People with facial allergies after heavy metal poisoning, people with long spots, and people with many red threads.
[0037] Trial results: Table 3 below.

[0041] As can be seen from Table 3, for the problems of allergies, long spots, and red blood streaks caused by heavy metals, the ingredients of the examples have obvious improvement effects, while in the comparative examples, due to the lack of one or more of fulvic acid, biochar, and kelp extract There are many kinds, resulting in insignificant or even no effect. It can be seen that fulvic acid, biochar, and kelp extract have a synergistic effect in improving allergies, spots, and r...
