Professional line cosmetics belong to the professional products of beauty salons. Compared with the cosmetics we use every day, the technical threshold is relatively high. Professional line cosmetics need beauty salons to provide professional services to consumers after the products are sold. The technology and requirements of professional cosmetics are different from those of daily cosmetics. The raw materials and quality used are higher than those of daily cosmetics, and the cost is often many times higher than that of daily cosmetics. At the same time, it needs the knowledge and experience of specialized personnel to use it.

Because of the market, there are few professional products and sales, and there are not many professional line products and brands that can be bought in the market, and their brands are often not those seen on TV. Therefore, cosmetics of daily chemical lines can often be bought in small shops or supermarkets, while cosmetics of professional lines can often be bought in places with exclusive stores or even exclusive operations.

The professional line skin care brand jointly developed by Kerowe (English trademark "codevy") and Bayer Group in Germany has been fully listed in China.

Its water cycle series combines pure natural plant essence and N2 energy factor, and combines two advanced high-tech technologies of "liquid nitrogen freezing" and "ultra-low-temperature critical extraction" to integrate the breakthrough technology of "liposome encapsulating active substances" for the first time in the professional cosmetics market, so as to improve skin problems such as dry lines, molting and sensitivity caused by water shortage. Water-locking factor quickly penetrates, replenishes needed high-quality lipids for skin, forms a protective film, and keeps skin moist and moist.
