How to read production and expiry date of our SK-II?

Updated: Two ways to check the production date of SK-II
It’s not fun to scratch your head and worry the number on the bottom of the bottle, especially when you shell out a fortune to buy an expensive product like SK-II.

You can have a peace of mind if you purchase SK-II from us as we are going to explain to you the production date that you see on our SK-II (you can use what's app to text us for the detail of our SK-II items or contact us here)

1) Use batch number to check production date of SK-II
We have received a lot of emails regarding the production date of SK-II. We can't reply them one by one but as always, you can use the batch number (see above picture) that printed on the bottom of the product to find out the production date. Just simply enter the number to below website and you will see the manufacturing and expiry date.


2) Use the five digit number on SK-II ingredient list
If you purchase from us, you will find five digit number printed on the ingredient list. This is production date shown in the format of Taiwan calendar (Minguo calendar).

Let us take the below item as an example, you can see five digit number 10607 on the bottom of ingredient list, it means the product is manufactured in 2017 (106+11) July (07). 

Simply speaking, 106 refers the year of Minguo 民國 and 07 refers to the month of production.

You don’t need to do the math or study Minguo history to understand the meaning of this 5 digit number as you can find the relation of Minguo calendar to the Gregorian calendar pretty easy on the internet. Here is the detail:
