I use this together with Cosrx A-Sol and other Cosrx products; and to be honest, my skin never felt better. This emulsion works great in hydrating my super dry skin and reducing excess sebum production. It is even suitable for super sensitive skin like mine, since they do not cause any break out for me. I always use them at night, and the next morning I wake up, my skin is super soft and smooth. I also notice a significant decrease in my white/blackheads after 2 weeks using Cosrx products.
