ALL Mary Kay products are stamped with a “Date Code.” This is a four digit code consisting of two letters followed by two numbers. This code is usually located on the bottom of a container or on the crimp of a tube. This is the date the item was manufactured.
For example, an eye color refill tray might be marked Crystalline #882800 KC05.
•“Crystalline” is the product shade name
• The six numbers (882800) indicate the part number
• The second four characters (FX05) indicate the date of manufacture, which in this example would be March 5, 2006.
The following products have a TWO YEAR shelf life:
Acne Treatment Gel
TimeWise Day Solution With Sunscreen SPF 15 & SPF 25
Sunless Tanning Lotion
ANY Mary Kay Sunscreen Product
Blemish Control Toner
You can interpret/decipher the day code using the following legend:
Character 1: Letter representing the year in the decade in which the product was produced.
Character 2: Letter representing the month of year in alpha order,
as follows (please note that the code skips some letters to avoid confusion and mistaken identification):
Characters 3 and 4: Numbers representing day of month.
If the date code is MA20, the the item was manufactured on January 20th, 2007!
