How to query sk2 batch number?

Firstly, the skii algorithm is queried by batch number.

Find the production date of the product (ten digits): usually the production date is marked on the bottom or body of the cosmetic bottle.

The first digit of the production date of SKII represents the year, and the second, third and fourth digits represent the number of days in a year.

2258211801represents the 258th day of 20 12.

Second, query through some cosmetics query tools.

1, concave APP, skills to check batch number identification products, but also remind cosmetics of expired shelf life. This product library is the most comprehensive.

2.checkcosmetic.com is a foreign website that specifically inquires about the batch number of cosmetics. A little knowledge of English will be more convenient to use.

3, corn rice APP, a tool for querying batch numbers.

4.beautykeeper's tool for querying the batch number of cosmetics can also remind the shelf life of cosmetics. If there are more than four products that need to be reminded of the shelf life, you need to pay.
