- Question: I use Yonka products. I know they have a short shelf life after being opened but I have no idea how to interpret the codes on the bottom. For example, I have a product with a code 9k 056a 20/10:41. Can you help me decipher this? Thanks! deb
You need to look on the back of the product.
There are different signs:
-3M means 3 months after opening the product, it starts to loose its actions,
-6M: 6 months,
-12M: 12 months.
Best skin care wishes.
