As mentioned in my previous post, one way to tell if you’re a MAC addict is when you’ve memorized the formula for computing the batch code of each item. In short, you’re a cosmetic calculator.
But what if, you’re a newbie, and you’re not familiar with this process? How is this interpreted manually?
Here’s the formula: ‘Batch run- Month-Year’
Step 1- Look for the batch code under your MAC product.
It’s the set of numbers with a letter (s) under the shade.
Here’s how to read it:
First Letter : Batch
* A : Batch 1
* B : Batch 2
* C : Batch 3
Second Letter Month
* January -1
* February -2
* March -3
* April -4
Third Letter: last digit of year of production.
If you’re like me, oftentimes too lazy to compute, simply go online and then type in the batch code.
Go to checkcosmetic.net and select MAC.
Type in your batch code (the letters you see at the bottom of your lippie or at the box) then the site will tell you if its expired or not, and of course, you’ll know how long it’s valid Easy right? Good luck!
