During the last twenty years, China has been the second largest cosmetics market in the world, behind the United States. In 2019, the size of domestic skincare market (excluding China Taiwan, Hong Kong and Macau) has been up to 244.4 billion. With the rapid development of cosmetics industry, the domestic market is awash with cosmetics of non-compliance and poor quality due to the lagged market supervision and lack of professional identification. Making use of customers' demand for getting beautiful quickly, fraudulent sellers add prohibited ingredients such as hormones, lead and mercury into cosmetics, which damages consumers' skin.
