I haven't done it at Dr. Cai's, but many of my colleagues do it there, and it costs 200 yuan. Many of my colleagues used to be made by her mother, but now her daughter is doing it, and my colleague will do it at 5 1, and it will be fine in a week or so. Not so swollen, because she is thinner and has mild skin. Recover quickly, just take some anti-inflammatory drugs. She also provides cell recovery fluid, 20 yuan. The effect is good and not expensive. You can buy it for use.
