[COSRX] THE 15 SERUM 20ML

The research-based derma line of COSRX was born, a prescription solution that optimally blends customized high-efficiency ingredients to solve skin problems and delivers them safely and effectively to the skin. This product is recommended for those who are concerned about blackheads/whiteheads, those who are worried about shine due to excess sebum, and those who are worried about rough skin texture due to dead skin cells. It is an A-to-Z solution product that can take care of skin problems, from the roots to the traces.

*Due to the characteristics of the highly concentrated serum formulation, which has a high content of active ingredients, if the content spills while opening and closing the container and is continuously exposed to the air, the active ingredients may become visible. *This is a normal phenomenon and there is no problem with the product, and it is safe to use.
