Hello, landlord, oral whitening products are effective. If external application doesn't work, you can really consider the form of oral administration. At present, there are many reliable brands in China, such as Yisheng He Kang's sea cucumber peptide, collagen peptide and sodium hyaluronate compound beverage, and Tomson Bianjian's collagen peptide is actually not bad.

Compared with other collagen peptides, Yishengkang Hejia oral liquid has no acne after drinking it first. If other families drink it every day, they will actually get acne for a while. Secondly, the whitening effect of his sea cucumber peptide drink is really good. The color difference between the front face and the neck is obvious. After drinking for more than half a month, I feel that the color difference between my neck and face is almost gone after makeup.

And because it is something to swallow, I think the brand must be guaranteed. Through Baidu and Zhihu, we checked the qualification background and comments about this brand, and found that it is a relatively large-scale enterprise in China, with research bases in the United States and famous R&D team. The landlord can try a new brand if he is willing to try ~
