How we pick a dupe · Disclaimer

We compare the full ingredient lists and only pair products that share core actives. Prices are checked against market listings to confirm the dupe really costs less.

This comparison is based on full-ingredient (INCI) data published under cosmetics law.

Shared ingredients mean the full-ingredient lists overlap, not that blend concentrations match; how a product feels and performs can differ by formulation and ingredient grade.

Prices are market-verified against stores such as Coupang and may differ from official store prices; discounts and temporary changes may not be reflected, so check the seller before buying.

For sensitive skin, eczema, pregnancy or other special cases, please do not decide on this analysis alone and consult a dermatologist.

Product images are displayed from Naver Shopping search results, and the rights to each image belong to the respective seller or brand.

This is an information service to support reasonable choices, and the final purchase decision is yours.
