Problems solved by technology

[0003] There are many types of skin care products on the market, but too many synthetic chemical agents are added to the existing whitening products, which can easily damage the skin
In particular, some whitening and freckle-removing cosmetics contain a large amount of preparations containing mercury and hydroquinone. Although they can quickly achieve the effect of whitening and freckle-removing, the accumulation of toxic substances will lead to necrosis of the facial skin of consumers, leaving incurable freckles or freckles. white block
At present, although hydroquinone has a good whitening effect, it is toxic and carcinogenic to the human body, so it is prohibited to use in resident products; arbutin has a good whitening effect, but it is easy to produce hydroquinone under certain conditions; ascorbic acid is not Stable, easy to be oxidized in neutral or alkaline solution, unstable under light and heat conditions, easy to turn yellow after storage for a certain period of time, so there are many ascorbic acid derivatives, such as ascorbyl phosphate, ascorbyl glucoside and ascorbyl ethyl Ether etc.
