1, pay attention to the production batch number. If you can't find the production batch number, it proves that this mask is fake. Don't buy it. The packaging of authentic masks is exquisite. The color saturation of the box paper is higher than that when the mask is opened, and there is nutrient solution residue in the package, which proves that this mask can be purchased. Some good masks should be the right size and suitable for clothes.

2, look at the film cloth, the thinner the mask, the better. This mask has a high nutritional content and belongs to silk mask. Of course, when choosing a mask, it still depends on the quality of the product. When the mask is pulled slightly, it will be severely deformed, and the mask looks thicker, which is an inferior mask. It is best not to use it, so as not to cause harm to the skin. In addition, a good mask can be touched by hand. If you think this mask is soft and smooth and can be perfectly attached to the back of your hand, then this mask can be used. In fact, you can judge the quality of the mask by looking at the mask packaging. There is no gap, the surface is clean, the brand name is clear, and you can buy it.

3. Looking at the packaging, the packaging of counterfeit products is rough, the logo or font on the packaging bag is not standardized enough, and the production date or batch number is unknown. The fake mask is cut randomly, and the texture of the mask is less than the essence attached to the mask, or the moisturizing effect is poor. There are indications that the quality of fake and shoddy products is not satisfactory and cannot be guaranteed. The unknown ingredients added in it often cause irreparable harm to the skin.
