How to Tell If a Korean Product Is Authentic
In short
- A price half the market rate isn't a bargain.
- Check the batch number and manufacturing date on the tube, not the box.
- A serious seller names their supply source when you ask for it.
- Be wary of marketplaces where anyone can sell.
K-beauty has become a global market, and like every fast-growing market it attracts counterfeiters. The most copied products are also the best known: snail mucin essences, hydrogel masks, headline serums.
A counterfeit cosmetic isn't a fake handbag. You put it on your face, sometimes around your eyes. Analyses carried out on customs seizures regularly turn up bacterial contamination, banned preservatives, sometimes heavy metals.
The warning signs
A price that's too low. This is the first clue, and the most reliable. Margins on these products are well known: nobody sells a €30 serum at half price for no reason. A 15 to 20% discount is credible; 60% isn't.
Sloppy packaging. Compare it with the images on the brand's official site: slightly different typeface, duller colours, blurred printing, mistakes in the Korean or the English. Counterfeiters take care over the box, rarely over the details.
An unusual texture or smell. If you already know the product and it smells different, or the colour has changed, don't use it.
No batch number. Every legal cosmetic carries one. Its absence is disqualifying.
A seller who stays vague. Ask where the product comes from. A serious reseller answers; a dubious one changes the subject.
Reading Korean dates
This is the most useful check, and nobody does it.
On Korean products, two markings usually appear on the tube or bottle in small print: MFD or 制 for the manufacturing date, EXP for the expiry date.
The format is most often YYYY.MM.DD. So "2025.03.14" means 14 March 2025.
Check that this information appears on the container itself, not just on the cardboard box. A box is easy to reprint.
Also look for the little open-jar symbol followed by "12M" or "6M": that's the period after opening, and it takes precedence over the expiry date once the product has been started.
Where the risk is highest
Open marketplaces, where any third-party seller can list an item under the same product page, account for most of the problem. You think you're buying from the platform; you're buying from an unknown intermediary.
Social media and private resale accounts are best avoided: no traceability, no recourse.
Unofficial direct imports raise a different issue: even when genuine, these products have no designated European responsible person, which the EU Cosmetics Regulation requires. If you react to one, there's nobody to turn to.
Questions to ask a seller
Three simple questions, and the answers tell you a lot quickly.
Where do your products come from? The expected answer names the brand or its official distributor.
Where do you ship from? Shipping from within the European Union means the stock has cleared customs and falls under EU regulation.
What's the manufacturing date of the batch in stock? A seller who manages their stock properly can answer.
How we work
Let's be specific, since this is exactly the subject.
We source from the brands and their official distributors in Korea, never from intermediary marketplaces. Labels and dates are checked on arrival, in France, before anything goes into stock. And orders ship from France, not from Korea: you pay no customs duties, and delivery stays at two to three days.
If you have any doubt about a product you've received, whoever sold it, write to us at contact@hulyabeauty.com with a photo of the batch number. We'll tell you what we think, even if you didn't buy it from us.
The habit to keep
A cosmetic product will sit on your skin for hours, every day, for months. Saving ten euros on a bottle isn't worth the risk.
Buy from the brand, from an authorised distributor, or from a reseller who can say where their stock comes from. That's the only rule that holds.
