Neither product lists paraben and mineral oil. The La Roche-Posay does list fragrance and phenoxyethanol though, so check the label if your skin tends to react to those.

Key shared ingredients · 2

The key ingredients both products share — the basis for the match.

PanthenolSoothingKorea MFDS-listedwidely used

Pro-vitamin B5, used to soothe and hydrate stressed skin.

Hyaluronic AcidHydrationKorea MFDS-listedwidely used

A signature humectant that pulls in and holds water, leaving skin hydrated and smooth.

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.

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.
