In fact, Lancome number and bar code can not be verified. Lancome manufacturers have never provided the service of scanning code to verify the authenticity. Lancome's products only have barcodes and QR codes on the packaging, which cannot prevent counterfeiting, but these do not have anti-counterfeiting functions.
If you are afraid of buying fake goods, you can go to official website, the State Administration of Medical Supplies, and look for information such as trademark, product name and manufacturer's approval number on the cosmetics navigation website. Check whether the information is consistent with the product packaging, and the result is clear at a glance. As long as it is ordinary cosmetics produced and sold in China or cosmetics imported and sold in China, it can be found in this way. If you can't find the information, it is a fake or parallel product, not a regular product, and it is risky to use, so it is not recommended to use it.
The result of Lancome's scanning code knot can not be used as an important basis for authentication. Although you can see all the information of the product after scanning the code, the fake can imitate the genuine barcode and code, so there is no anti-counterfeiting function.
