Buying genuine products and spotting fakes

The safest options are brand flagship stores, official online shops, department stores, duty-free shops, and major cosmetics retailers with clear supply chains. On open marketplaces, confirm that the seller is an official store or a brand-authorized retailer. Avoid sellers of unclear origin that advertise suspiciously low prices.

With counterfeit cosmetics, you cannot know what ingredients were used or how they were made, so there may be risks of irritation or contamination. If something goes wrong, it is hard to trace the maker or get compensation. If your skin reacts after using one, stop immediately and consult a dermatologist.

Korean cosmetics must show key details in Korean on the outer packaging, including the product name, the business name and address, the full ingredient list, the expiration date or period after opening, and a batch number. The inner container carries only some of these, such as the name, business name, batch number and date. If details are missing, blurry, or full of typos, look closer.

Blurry or off-color printing, spelling mistakes, sloppy finishing, an unusual scent or texture, and prices that seem too good to be true can all be warning signs. Still, it is hard to spot a fake perfectly by appearance alone, so buying from reliable sellers remains the best protection.

Some brands add anti-counterfeit stickers, QR codes, or holograms to help verify authenticity. These can also be copied, though, so they are not proof on their own. When you scan a QR code, make sure it leads to the brand's official website, and contact the brand's customer service if you have doubts.

With street stalls or sellers of unclear origin, it is hard to confirm whether products are genuine or how they were stored. Items left in sun and heat for long periods may also have degraded. Since you put these products on your skin, buying from a proper store is the safer choice.

Overseas, it is safest to buy from the brand's official store or from retailers listed on the brand's official list of authorized sellers. Check seller ratings, reviews, business details, and return policies. If the same product is being sold in large quantities at an unusually low price, think carefully before ordering.

Parallel imports are genuine products brought in through channels other than the official importer, so they are not automatically counterfeit. However, it can be harder to verify how they were shipped and stored, and the brand may not provide customer service for them. Evaluate the seller's reliability carefully before buying.

Look for the expiration date or the period after opening on the package. The period after opening can be written out in words or shown as an open jar symbol with a number of months, such as 12M, and products that use it must also show the manufacturing date. If a product is past its date or its color or smell has changed, do not use it.

A batch number lets a product be traced back to when and where it was made. If a problem occurs, the brand or retailer uses it to look into that specific product. If a batch number is missing or has been scratched off, it is reasonable to question whether the item came through normal distribution.

With social media group buys or private sales, it is often hard to verify the seller's identity and where products came from. Check whether business registration details are shown and whether there is an exchange and refund policy. Protection can be limited if something goes wrong, so be extra careful with larger purchases.

Korean online shops usually display the company name, representative, business registration number, and mail-order business report number at the bottom of the page or in a seller information section. Be cautious if these details are missing or cannot be verified. You can look up business details through the Fair Trade Commission's search service.

Stop using it and keep the receipt, payment record, and photos of the product and packaging. Contact the seller first, and if that does not resolve it, ask the brand's customer service or the Korea Consumer Agency for help. If your skin reacted, see a dermatologist and keep the medical records.

Yes. Selling counterfeits that misuse a trademark can be reported. As of November 2026, reports and crackdowns are handled by Korea's national intellectual property authority through its IP infringement reporting center. Safety issues with the cosmetics themselves can go to the Ministry of Food and Drug Safety, so check each agency's official website.

Licensed duty-free shops in Korea, legally called bonded sales stores, operate under a license granted under the Customs Act and are supervised by customs. Shopping at official airport, downtown, or online duty-free shops greatly reduces worries about fakes. Be wary of websites that only pretend to be duty-free shops, and check the address and operator.

Brands sometimes change packaging designs, containers, or formulas when they renew a product, so it may look different from the older version. Check the brand's official website or social media for renewal announcements. If you still have doubts, contact customer service with the batch number for a definite answer.

When unsold brand samples are bundled and resold, it is hard to verify where they came from, how they were stored, or when they expire. Some samples are even marked as not for sale. Since these products go on your skin, buying from sellers with a clear supply chain is the better choice.

Cosmetics officially sold in Korea are required to carry Korean labeling, so if a product in a Korean store has no Korean text at all, it is worth checking further. Export-only products may be labeled in the destination country's language, so when abroad, also confirm whether the seller is officially authorized by the brand.

Many brands accept authenticity inquiries through customer service or official social media. Sending product photos, the batch number, and where you bought it speeds things up. Some brands do not offer verification, so follow the official guidance each brand provides.

Confirm the seller is official, check for Korean labeling, a batch number and expiration date, be wary of unusually low prices, and look for seller details and a refund policy. Keep receipts and payment records, and stop using a product right away if anything feels wrong. These habits alone greatly reduce your risk.
