1. Check whether the certificate number is printed on the packaging box, whether there is a scannable bar code, and whether there is a production date/expiration date of the steel seal on the mask bag. If not, it's fake.

2. On the official websites of the Food and Drug Administration and the Quality Supervision Bureau, check whether the company has successfully filed and passed the quality inspection. If it is not filed and fails the quality inspection, it is fake.

3. Check the mask package to see if the manufacturer, producer, production address, production license number and other details are clearly written on the package. Without these details, it is fake.

note:

1, be sure to compare whether the product names and ingredients recorded by the Food and Drug Administration are consistent.

Do you want to check whether there is a registered trademark on the box? And food safety label QS.
