Sales were lower than expected. Bayunkou is a cosmetics brand under Peking Union Medical Cosmetics Technology Development Co., Ltd., and passed the trademark certification of the Intellectual Property Office on 20 14. Because the sales of this product failed to meet expectations, the boss could not make money, which led to the closure of the flagship store. Bayunkou is a skin care brand with herbal/woody extracts as the main component. Adhering to the brand concept of nature, health and beauty, professional R&D team and standardized production process, Bayunkou is committed to creating reliable high-quality skin care products.
