Problems solved by technology

[0010] (2) Product stability is low. Many anti-oxidant chemical functional ingredients of whitening cosmetics have one or several unsaturated double bonds. These functional ingredients can inhibit melanin in the skin due to their strong reduction , but when it is made into finished cosmetics, because it is exposed to the air for more than a month or even a few days, the unsaturated bonds are denatured and inactivated under the action of oxygen, light, metal ions, etc., and the whitening activity is lost, so that the whitening effect is relatively weak. Difference
[0011] (3) The whitening pathway is single, and melanin is produced through a series of complex chemical reactions, and there are multiple pathways to inhibit its production
However, various whitening additives can only inhibit one pathway, but fail to fully inhibit melanin.
[0012] (4) Existing whitening cosmetic products intentionally add a variety of chemical ingredients and use hormones in order to reflect the effect. Although they have a whitening effect on the skin and can reduce wrinkles, some cosmetic companies will add prohibited and restricted substances to their products ( such as antibiotics)
[0015] There are many whitening active ingredients that have been proven to have significant whitening effects, but due to various defects such as irritation and instability, the application and efficacy of the products are greatly limited
