There are no conclusive laws and regulations stating that silicon-containing raw materials are harmful to the human body. As long as the raw materials used can be found in the “Catalogue of Names of Used Cosmetic Raw Materials (2015 Edition)”, they are legal and compliant. Of course, the prerequisite for legal compliance is that the amount added is within a certain range. For example, everyone knows that skin care products that add glycerin have a moisturizing effect, but if the glycerin content is added to a high level, the glycerin will absorb moisture from the skin, which will have the opposite effect.
