1. Xiyan is a professional skin care brand that combines European cutting-edge skin care concepts with traditional medical care concepts in China. Adhering to the concept of safety, health and zero burden, it has always had a good reputation and a good whitening effect. The whitening effect and word-of-mouth of Feiyanquan are not as good as Xiyan.

2. It's convenient to smile and the effect is very good. It is a product worth buying back. Nice refreshing drink.
