Ingredient Guide

Korean skincare formulas often combine multiple active and supportive ingredients, so a single product may fit more than one ingredient category.

Build your routine around your primary skin goals rather than choosing products based on one ingredient alone.

When introducing stronger actives such as retinol, retinal or concentrated vitamin C, begin gradually and follow the product directions.
