SK-II
SKIN1004
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
Both products lean on the same core active: a KFDA-notified brightening vitamin B3, also widely used for hydration and barrier support.
Across the full lists, both focus on moisture, brightening, soothing and antioxidant. They don't share every ingredient, but the payoff lands in a similar place.
The SK-II side does include fragrance, phenoxyethanol, benzyl alcohol, sodium benzoate and methylparaben, so if fragrance or preservatives are a concern, the SKIN1004 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 87%, or roughly ₩243,150. If you want a similar ingredient makeup at a lighter price, this is an essence worth trying first.

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 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.
