Where does Changchun treat acne with good effect?

Buy a combination of blue and gold, which is very useful. At first, my face will turn red, which lasts for about a month. It's normal. Then began to shed some skin, and finally the whole course of treatment lasted for a month. I'm not a drug salesman. I tried it myself. It turns out that I used a lot of drugs and it didn't work. This effect is the best.
