Why this dupe
The proof is in the ingredients, not the price
Hyaluronic Acid, Phytosphingosine and other key ingredients appear in both full ingredient lists.
In the full lists, 15 ingredients overlap.
Who it's for
A good fit if you want to refill dryness while caring for firmness and wrinkles. Both use hyaluronic acid and barrier-replenishing ingredients to hold moisture and support firmness.
Mediheal also adds a soothing ingredient, so it stays gentle on sensitive skin.
What works and what to weigh
- More moisture and firmness than the original
- Barrier-replenishing ingredients too
- Silicone-free
- About 94% cheaper
- –The original adds more firming and ingredients like ginseng extract. Mediheal still covers moisture and firmness well.

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.
Part of the skin barrier that helps soothe and hydrate.
Neither list has a preservative-type marker with a known concentration cap. So we cannot tell how much of each shared ingredient these two products actually contain, and we would rather say that than guess.

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.
