Yves Saint Laurent
La Roche-Posay
Compared by full ingredient list. It does not mean concentration or texture are identical, and prices are as of the listed time.
What the ingredients show
The two products share a couple of core actives. One is a KFDA-notified brightening vitamin B3, also widely used for hydration and barrier support; the other is an AHA that gently clears away dead surface cells.
Across the full lists, both focus on moisture, brightening and exfoliation. They don't share every ingredient, but the payoff lands in a similar place.
Neither product lists paraben, silicone and mineral oil. The Yves Saint Laurent side does include fragrance, sodium benzoate and potassium sorbate, so if fragrance or preservatives are a concern, the La Roche-Posay option may sit easier.
A close ingredient list doesn't mean the strength or the texture matches. The same ingredient can feel different depending on how much is used and how it's made, so treat the shared ingredients as a starting point rather than a promise.
The price gap is about 50%, or roughly ₩60,390. If you want a similar ingredient makeup at a lighter price, this is an essence worth trying first.

Shared ingredients mean the full-ingredient lists overlap, not that blend concentrations match; how a product feels can differ by formulation and origin.
Prices are market-verified against Naver and Coupang and may differ from official store prices; discounts and temporary changes may not be reflected, so check the seller before buying.
