What is a Batch Code?

The batch code, also known as a batch number, production code, or lot number, is a set of letters and numbers printed by manufacturers on the packaging of cosmetics or perfumes during the production process.

It is used to identify the production batch of the product, helping manufacturers track the product when necessary. For consumers, it is a crucial clue to check fresh and check exp by determining the product's manufacturing date and shelf life.

Where Can I Find the Batch Code?

The batch code is typically located in one of the following places on the product packaging:

1

On the Outer Packaging Box

Check the bottom or side of the product's outer packaging box

2

On the Bottle or Bottom

If the outer packaging is missing, check the bottle itself or the bottom

3

On the Product Label

Sometimes the batch code is printed on a label attached to the bottle or lid

4

At the Product Seal

In some products, the batch code might be printed on the seal area

What If the Batch Code Is Hard to Identify?

If the batch code is difficult to identify due to wear or other reasons, you can try the following methods:

  • Magnifying glass: Use a magnifying glass or the zoom function on your phone to closely examine the code
  • Lighting: View the code under different lighting conditions; sometimes, side lighting can reveal faintly printed codes more clearly
  • Customer service: Contact the customer service department of the product, providing the information you have about the product

How Long Do Cosmetics Stay Fresh?

When it comes to cosmetics, determining their freshness isn't always as straightforward as checking a simple date. The longevity of these products hinges on two key factors: the Period After Opening (PAO) and the production date.

Period After Opening (PAO)

The PAO signifies how long a product remains effective and safe after its first use. This is crucial because, upon opening, cosmetics are exposed to air and potential contaminants, which can accelerate the degradation process.

Look for the open jar symbol on packaging, which includes a number indicating the safe usage period in months. For instance, a "6M" symbol means the product should ideally be used within six months after opening.

6M

6 months

🫙
12M

12 months

🫙
18M

18 months

🫙
24M

24 months

Production Date & Shelf Life

The production date reflects when the product was made. Over time, even unopened cosmetics can lose their freshness, drying out or changing in texture. According to EU regulations, only products with a shelf life of less than 30 months are required to display an expiration date.

To check fresh, here's a general guideline on the durability of various cosmetics from the date of manufacture:

🌸 Perfumes with Alcohol

~5 years

Longest shelf life due to alcohol content

💧 Skin Care Cosmetics

3+ years

At least 3 years unopened

💄 Makeup Cosmetics

3-5+ years

Varies by type (mascara to powders)

🌿 Natural/Organic

1-2 years

Shorter due to natural preservatives
