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. Meagan, Esthetician
