Korean Skincare Ingredients
Understanding what is in your skincare products helps you make informed choices. This library covers the most significant ingredients in Korean skincare — what each one does, which skin types it is suited to, and how to incorporate it into a routine.
Korean skincare draws on both traditional botanical heritage — ginseng, rice, green tea, mugwort — and cutting-edge cosmetic science. Many Korean formulations layer multiple complementary ingredients rather than relying on a single active.
