COSRX Low pH Niacinamide Cleansing Water refreshes the skin while removing buildup and light makeup. It supports oil balance, soothes irritation, and keeps the skin hydrated without disrupting the skin barrier.

How does this COSRX Low pH Niacinamide Cleansing Water work?

Micellar particles trap and lift away impurities, while ingredients like niacinamide and zinc PCA help to refine pores and balance oil. Added hydrators ensure the skin feels calm and comfortable after cleansing.
