Secret batch codes of beauty products

secret code

Okay, confession time.  Do you ever bother to check the expiry date on your beauty products?  Well, I don’t.  I’ve not given this much thoughts plus there isn’t an expiration date for most products anyway because there’s no legal requirement to use expiry or use-by dates on the majority of products.

In fact, only products that won’t last longer than 30 months need to show a use-by date in the form of a month and year, whereas all other products don’t need one.  But of course, all products do have a shelf live especially skincare products that contains preservatives or “all natural” products that contain plant-derived ingredients.

3 years shelf life
From what I read, most products without a use-by date should be used within three years of leaving the factory.  If you keep them longer than that, they no longer work well and you increase the risk of contamination, particularly because of the repeated microbial exposure during use.  In fact, eye care products have even shorter shelf life and items like mascaras are recommended to be replaced 3 months after purchase.  

So how do we know when the product was manufactured?  The answer is to look at the batch code on the product package.   Batch codes are always printed on the package with different font from the product specification.  If the package is a bottle, the code can be found at either the bottom or the side of the bottle.  But figuring out the batch codes can be tricky.  An example is this that I picked out from various beauty forums.

The batch code on brands under Estee Lauder Group such as Mac, Estee Lauder, Clinque, Origins or La Mer uses 1 letter + 1 digit (or letter) + 1 digit.  The letter refers to the location,  the fist digit (or letter) corresponds to the months from January to December respectively while the last digit denotes the year (1: 2001, 2: 2002, etc). 

The batch code on brands under the L’oreal Group such as L’oreal, Lancome, Biotherm, Helen Rubinstein, Kiehl’s or The Body Shop begins with a letter for location, and a letter for year, and 3 numbers for days. A stands for 2004, B stands for 2005. Z is skipped, because it looks like “2″, so “Y” would denote 2003. The digit stands for the number of the day in a year (eg. 200th day) when the item was manufactured.

L’Occitane uses 3 digits and the first two denotes the week while the last refers to the year.  Christian Dior uses a combination of numbers and letters but only the first two are important with the year as denoted in the 1st digit, followed by a letter denoting the month starting with A for January up to M for December (the letter I is skipped). On the other hand, Clarins uses a number to denote the year, followed by two numbers for the month and another three numbers to identify the specific batch. 

If you think this is too complicated, think about the fact that there are so many different manufacturers and they actually use different coding system.  It’s almost like a secret coding, probably used to track counterfeits.

The good news is that there are now online resources to help you figure out although they’re rather limited at this stage.  Like the Cosmetics Wizard which is a calculator to help you calculate your cosmetics’ production date from the batch code on product package.  It’s still a beta version and currently only tracks 27 brands.  But hopefully, with increased usage, the database will expand to include more brands.

At the end of the day, I believe there is a bit more self learning to be involved.  It depends if we want to be proactive in finding out if the products we use on our skin is indeed safe or fresh.  Or are we just leaving it to chances because we’re not aware, or worst, can’t be bothered.  (Okay, I’m talking about myself here.)

    Thanks for your de-coding. Elizabeth Arden has a different coding system, one digit followed by two letters. Do you know how to read the code as well? Thanks!

    Li: I’m not exactly familiar with EA’s but I believe the first digit refers to the year while the two letters, the month. But I have no idea how the month is read though.

    I still cannot understand the japanese way of batch coding the products (not only cosmetics). They use f.e.: 2027,+352…..730921240CO351 or UXA2, or E56GJ.
    I would be very grateful if somebody could explain how I can read them.
    Thanks.

  20. Tracey Says:

    Thanks for the information on batch codes! I am horrified to find some of the products I have bought are old and others I am now wondering if they are counterfeit. Is there a way of finding a database with Lancome codes on it to check if they are genuine or not? The products I am questioning are gift with purchase size so I’m not sure if the batch numbers differ for those?
    Many thanks

    Tracey: I’m not sure if the codes are different for samples but a good way is to write in and check just to make sure they’re not counterfeits.

  21. Rachel Says:

    Thanks for the info! Do you know anything about Murad’s batch codes? Would “N4D1″ mean it was produced in 2001?!

    Rachel: Sorry, I have no idea about Murad’s. You may want to write to the company to ask. They should answer.

  22. Simon Says:

    Hi,

    Do you know how to decipher Lancome batch codes that don’t follow the pattern mentioned above (ie. 2 letters followed by 3 numbers).

    Some Lancome “Gift with Purchase” products have a batch code of 6 numbers/letters, eg.

    18E302
    18DD03
    18DD02

    Do you know how to determine the production date from these batch codes?

    Also, is it possible to confirm the actual Lancome product simply from the batch code?

    Thanks

  29. RGM Says:

    I think L’oreal products changed the way they publish batch numbers. The first half of 2008, it’s exactly how you describe it; however, after this date, it’s entirely different. For example, My Lancome Pure Focus cleanser has “40E902″ as the batch number (it’s authentic, bought it in a Lancome boutique). Does anyone know how to read it?

    This website is great. Now I know how to read expiry date codes. Boots the Chemist have over the past few years given me Clarins samples to try which are out of date. Surely this is illegal?

    Maybe they think it’s because it’s samples but they shouldn’t be given them out if they’ve expired.

  37. Fiona Says:

    I recently purchased a Kerastase Shampoo bottle from a retailed shop with half the price I see on the Internet. From what I understand, this would be a L’oreal Paris product. However, it doesn’t have an expiry date, only a PAO of 12 months. I am afraid that this could be a counterfeit cuz the batch code does not match what you described (2 letters, 3 digits). It says 3 474635 003762. Can you help me figure it out?

    I think you didn’t read proper batch code. Please find another code on your bottle.

    As far as I know now The Body Shop belongs to L’Oreal. So this code seems to be strange and doesn’t look like code Body Shop and L’Oreal. So are you sure that you read right value?
