The date of domestic masks is generally printed on the outer packaging box or on the edge of a single mask, and the production date is seen from left to right. The production date of masks abroad is quite special, generally read from right to left, such as MFG2205 18, which means that the production date is May 22, 20 18. The shelf life of domestic patch masks is generally on the box and the outer packaging bag. Foreign veneered masks generally use small jars to indicate the shelf life.
Domestic patch masks are usually packed in a box of 5- 10 tablets, and the production date is on the packaging and outer packaging. In general, the date will be printed on the package, and there will be a steel seal on the package. The shelf life of the mask is three years, and the unopened mask can be used within the shelf life. After opening, the shelf life will be shortened according to the mask. If it is a patch type, use it immediately after opening it.
Preservation method of facial mask:
First, put it in the refrigerator for cold storage.
Keep the mask in the refrigerator. I believe many girls know that they also enjoy the cold feeling of taking out the mask from the refrigerator and applying it to their faces. After the mask is taken out of the refrigerator, it will strengthen the calming effect on the skin and be beneficial to the skin. Moreover, some masks that are not individually packaged should be kept in the refrigerator after opening.
Second, not all masks need to be refrigerated.
Some masks are not better because of refrigeration. Under normal circumstances, individually packaged masks are relatively stable and can be stored normally even at room temperature, so it is not necessary to put them in the refrigerator, especially in winter, and they will not feel cold and uncomfortable when used.
