See all 41 Lancôme dupes →As of Jun 27 · Prices reflect public listings on stores such as Coupang and may vary by store or promotion.
Why this dupe
The proof is in the ingredients, not the price
Hyaluronic Acid, 비타민C, Ferulic Acid and other key ingredients appear in both full ingredient lists.
In the full lists, 12 ingredients overlap.
Who it's for
Good for anyone who wants hydration with a bit of firmness. Both products carry hyaluronic acid for moisture and an antioxidant ingredient, so they cover a few concerns together.
What works and what to weigh
- Hydration & firmness on par with the luxury pick
- The dupe is fragrance free
- About 89% cheaper
- –The luxury pick adds a tone-care ingredient and a UV-blocking ingredient, so it works with a few more ingredients. If you want that extra, the gap remains.

Key shared ingredients · 3 (2 uncommon)
The key ingredients both products share — the basis for the match.
A signature humectant that pulls in and holds water, leaving skin hydrated and smooth.
A plant antioxidant known to help stabilize vitamins C and E.
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.
Full ingredient comparison

Ingredients are listed by amount. Below 1%, brands may list them in any order, so ranking there means little.
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.
