Counterfeit goods, compared with what I bought at the pharmacy, I also checked the information about Xueyan on the Internet. First of all, the real snow swallow will not have a strong smell, and it is very transparent after the hair is made, and the drawing is uniform. It is exactly the same as the description of Xueyan I bought at the pharmacy. The snow swallows bought here are not only packed in the same way as Taobao, but also have a strong and pungent sour taste after opening. Normally it should be a touch of sourness. This is especially strong and transparent. Very bad sex, no pharmacy crystal clear, and very fragile, uneven thickness. In the picture, the left side is for the pharmacy, the right side is the weee product, and the right side is obviously white and there is no left side. If you don't believe, you can go to the pharmacy to buy some comparisons.
