Why this dupe

The proof is in the ingredients, not the price

Hyaluronic Acid, Lactic Acid, Ceramide, Phytosphingosine and other key ingredients appear in both full ingredient lists.

In the full lists, 16 ingredients overlap.

Who it's for

Good forDrynessBarrier & texture

A good fit if you want to refill the eye area while clearing dead skin. Both use hyaluronic acid and barrier-replenishing ingredients to refill dry skin and add an exfoliating ingredient.

What works and what to weigh

Upsides
  • Moisture and exfoliation on par with the original
  • Fragrance-free and lighter on skin
  • About 88% cheaper
Trade-offs
  • The original adds more firming and wrinkle-care ingredients. If you want more than moisture, that gap remains.

The lists are long, so the reference line lands late and the reading becomes unreliable. So we cannot tell how much of each shared ingredient these two products actually contain, and we would rather say that than guess.

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

Before you reach for this dupe

  • COSRX includes an ingredient that clears dead skin, so wear sunscreen during the day while you use it.

How skin responds to ingredients varies from person to person. If your skin is sensitive or you have a specific condition, check with a doctor first.

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.

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