Why this dupe
The proof is in the ingredients, not the price
Camellia Sinensis Leaf Extract, Hyaluronic Acid and other key ingredients appear in both full ingredient lists.
In the full lists, 4 ingredients overlap.
Who it's for
A good fit if you want to fill dryness while also tending to soothing. Both products carry hyaluronic acid for moisture and green tea that helps with soothing to keep skin comfortable. What the two share are common moisture ingredients, so moisture is the main thing to expect.
What works and what to weigh
- Moisture & soothing rival the luxury
- Fragrance, paraben & silicone-free
- About 98% cheaper
- –The luxury one adds ingredients that clear dead skin, so it works with a few more ingredients.

Key shared ingredients · 2
The key ingredients both products share — the basis for the match.
A green tea extract with antioxidants like catechins that keeps skin feeling fresh.
A signature humectant that pulls in and holds water, leaving skin hydrated and smooth.
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.
Full ingredient comparison
Both full ingredient lists compared. More shared ingredients means a closer match.
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.

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.
