How to tell a genuine Korean product from a fake

Check the regulatory text, which is what fakes most often get wrong: full Korean ingredient list, manufacturing or expiry date, batch code, importer details and any 기능성화장품 marking. Then check the price and the seller. Deep discounts on popular products through unofficial channels are the most reliable warning sign of all.

Regulatory text is hard to fake well

Korean packaging carries dense mandatory text. Counterfeits routinely get it wrong — missing batch codes, misspelled Korean, absent manufacturer details, or a functional-cosmetic marking on a product that should not have one. It is the first place to look.

Price and channel

Price on its own is a weak signal in this market: Olive Young sale weeks, 1+1 promotions, brand outlets and duty-free all discount genuine stock heavily and legitimately. What matters is price plus channel. A viral product at a fraction of its usual price, from an unfamiliar marketplace seller with no official-retailer paperwork, is the classic profile.

Physical tells

Print quality, colour accuracy against official images, seal integrity, and the texture and smell of the product itself. Fakes often approximate the packaging closely and the formula not at all.

How to buy safely

Brand-official stores, Olive Young's official channels, and established retailers. If you are buying in Korea, Olive Young and department-store counters are straightforward. The saving from an unofficial seller is rarely worth putting an unknown formula on your face.
