Cosrx has made a huge global impact and was one of the first brands to use the principles of K-beauty to formulate products for a global market. Because of this, all of their products focus on simplicity, using only what is needed, and catering towards hydration and care rather than stripping the skin with too many actives.

With a lower pH however, this product is able to remove dry, grime and oil from your skin without stripping it of its natural moisture.
