IOPE XMD Stem3 Clinical Recovery Serum vs COSRX Advanced Snail Mucin Glass Glow Hydrogel Mask
See all 65 IOPE dupes →As of Aug 9 · 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
Niacinamide, Hyaluronic Acid and other key ingredients appear in both full ingredient lists.
In the full lists, 13 ingredients overlap.
Who it's for
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 and mineral oil. The COSRX option also skips silicone, handy if those are on your avoid list.
What works and what to weigh
- Moisture on par with the original
- Free of fragrance, paraben and mineral oil
- About 33% cheaper
- –The price gap is not large, so the original is also worth considering for deeper care.

Key shared ingredients · 2
The key ingredients both products share — the basis for the match.
A Korea MFDS-notified brightening vitamin B3, also widely used for hydration and barrier support.
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.

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.
