Buying K-beauty online: authorized sellers and fakes
Popular Korean skincare gets copied, and some products reach the US through gray-market channels. A few habits lower your risk.

Start with where it is sold
- Check the brand's own website. Many brands list their official stores and authorized retailers.
- Be careful on open marketplaces, where many sellers can share one product listing. Look for the line that says who the product ships from and who sells it. There are regular reports of counterfeit beauty products on large marketplaces, so a listing sold by the brand or an authorized seller is a safer choice.
- Check the return policy before you buy, particularly for skincare, which many sellers won't take back once opened.
Warning signs
- A price far below every other seller, especially on a very popular product.
- Packaging, fonts or colors that look different from the brand's own photos.
- Missing or hard-to-read batch codes, or an expiry date that has passed or is very close.
- Reviews that mention a different smell, texture or color than expected.
Read the package when it arrives
- Batch code or lot number. Usually printed or embossed on the box and the container. They should match.
- Expiry date or the open-jar symbol. Skincare often shows a jar icon with a number, such as "12M," meaning it should be used within that many months of opening.
- The ingredient list. See our ingredient guide. Compare it with the brand's website.
- Seals and condition. Don't use a product with a broken seal, leaks, an odd smell or a changed texture.
Different versions of the same product
Some brands sell different versions in Korea, the US and other regions, with different packaging, sizes and sometimes ingredients. This is especially true of sunscreens (see our sunscreen guide). A Korean-market item on a US store can be perfectly genuine and still not match the US version. Read the listing to see which one you are getting.
If something looks wrong
Stop using it, keep the packaging, and contact the seller and the brand. If it caused a reaction, see a doctor.
