I am so disappointed. I didn't tell you what caused my acne, and I didn't test my skin. I just experienced it, and my face was red and swollen. It seems that the customer spent less money and was slapped. Since it is a group purchase, don't be afraid that everyone will buy it. Really, your attitude is terrible. I really can't see where the major is. I have bought it so many times, and I have met such a merchant for the first time. Friendly reminder: think twice before you go to the group buying experience!
