I haven't used it. Personally, I think you are really worried about going to see an old Chinese doctor. I don't trust western medicine very much, because it is the hormone ointment they gave us, and then let us suffer from hormone dermatitis, and then tell us openly that we have this hormone dermatitis, and then recommend other ointments to us. I am disappointed and afraid to use it. I have been seeing Chinese medicine since then. To be honest, you might as well consult Chu Qing, the Qi Chen Tang of Taobao Store, who is all about skin care.
