My dermatologist recently gave me a Korean product similar to this one but it was expensive and I could not find the same brand on Amazon, so decided to try this one instead. They work exactly the same. I like it, I have a sensitive skin and I do not have any problems with this product. after you put on a decent amount, wait 30-40 seconds and your face gets covered with a very thick white foam. Even after massaging the face, the foam comes back, so I like it. I generally use it before my shower because otherwise it gets into my hair. I think this is a good cleanser.
