How to Check Expiry Dates on Imported Skincare

You finally got your hands on that pricey imported serum—but before you slather it all over your face, have you checked the expiry date? Expired skincare isn’t just useless; it can irritate your skin, cause breakouts, and even lead to infections. The problem? Many imported products don’t follow the standard expiry date formats we’re used to in Pakistan. So, here’s your go-to guide for making sure your skincare is still safe to use.

1. Expiry Date vs. PAO (Period After Opening)

Some international brands don’t print a clear expiry date. Instead, they use:

• PAO Symbol (Open Jar Icon): A tiny jar icon with "12M" or "24M" means the product is good for 12 or 24 months after opening.
• Batch Code: A set of numbers and letters that require decoding (don’t worry, we’ll get to that in a second).

2. How to Decode Batch Codes

Most international brands rely on batch codes instead of straightforward expiry dates. Here’s how to read them:

• Check the Brand’s Official Website – Some brands provide batch code decoders.
• Use Online Checkers – Websites like CheckFresh and CheckCosmetic let you enter batch codes to find the manufacturing date.
• General Rule: Most unopened skincare products last three years from the manufacturing date—if stored properly.

3. Expiry Guidelines for Common Skincare Ingredients

Not all skincare expires the same way. Here’s when to toss your favorites:

• Niacinamide – Stable but loses potency after 1-2 years. Want to know if yours is still effective? Read Can Skincare Expire? Shelf Life of Niacinamide/Vitamin C.
• Vitamin C Serums – Oxidizes fast. If it turns yellow or brown, it’s time to say goodbye.
• Sunscreen – Most expire within three years, but heat exposure can break them down faster.
• Retinol – Loses potency after 6-12 months once opened. If it stops working, it’s expired.

4. Expiry Formats Based on Region

Different countries label skincare differently. Here’s what to look for:

• Korean Skincare – Often marked with "제조" (Manufactured Date) and "까지" (Expiration Date).
• European & US Brands – Usually follow the "Month/Year" format.
• Japanese Skincare – Relies heavily on batch codes, so always double-check before buying.

5. Storage Tips to Extend Shelf Life

• Store skincare in a cool, dark place—heat and humidity speed up expiration.
• Keep Vitamin C and retinol in the fridge to slow oxidation.
• Always tighten caps properly to prevent contamination and bacteria buildup.

Final Thoughts

Checking expiry dates on imported skincare takes a little extra effort, but it’s worth it. Protect your skin (and your money) by checking batch codes, storing products correctly, and knowing when to toss old skincare.
