Medical masks are not medicines, they are cosmetics. Medical masks are generally prescribed by doctors or professional medical institutions, but medical masks are not medicines and do not necessarily need to be used when there is a skin condition. The facial masks that everyone buys in supermarkets, cosmetics stores or various purchasing agents are generally ordinary facial masks. Medical facial masks must be different from ordinary facial masks. The essential difference is that the production specifications of cosmeceuticals are implemented in accordance with the quality standards of pharmaceuticals. Regardless of whether there are additives or not, the basic standard is that it is non-allergenic or hypoallergenic. It is a mask with a medical device production license. Strictly speaking, it is a medical device, with high entry barriers and stricter production specifications.
