Why this dupe

The proof is in the ingredients, not the price

Bifida Ferment Lysate, Hyaluronic Acid, Bisabolol and other key ingredients appear in both full ingredient lists.

In the full lists, 11 ingredients overlap.

Who it's for

Good forDrynessDullness & spots

Across the full lists, both focus on moisture, brightening, firmness and soothing. They don't share every ingredient, but the payoff lands in a similar place.

Neither product lists fragrance, paraben, silicone and mineral oil. The Estée Lauder side does include potassium sorbate and phenoxyethanol, so if fragrance or preservatives are a concern, the numbuzin option may sit easier.

Compared by full ingredient list. It does not mean concentration or texture are identical, and prices are as of the listed time.

How we pick a dupe

We compare the full ingredient lists and only pair products that share core actives. Prices are checked against market listings, and ingredients with Korea MFDS usage standards are flagged on the page.

Disclaimer

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.
