SK-II
Olay
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 amino-acid chains widely used for firmness and skin texture.
Across the full lists, both focus on moisture, brightening and firmness. They don't share every ingredient, but the payoff lands in a similar place.
The Olay does list fragrance and phenoxyethanol (kfda usage limit) though, so check the label if your skin tends to react to those.
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 62%, or roughly ₩107,670. If you want a similar ingredient makeup at a lighter price, this is a serum worth trying first.

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.
