The effect of fruit acid is good, but the late reaction of fruit acid is also relatively large. It is equivalent to fruit acid changing skin and has a strong burning feeling. The price of black dolls has different charging standards in different hospitals, and the specific price should be calculated according to each course of treatment and the number of treatments. If you do it for 3-6 times, the price is about 8000- 1000, and the skin treated by the system has better cosmetic effect, lasting for more than 2-3 years, with high cost performance. In order to try the effect of black-faced doll, most people choose to do black-faced doll treatment, but the effect is not so obvious. I heard that it takes many times to be effective, and the effect of shrinking pores is the most popular method. Generally, a plastic surgery hospital costs 200 to 2000 yuan at a time, and the price of different parts will be different. Generally, a course of treatment is 3-5 times, and it is better to do it once every three months, but maintenance and nursing should be done well in the later stage. I hope I can help you, thank you! In fact, I want to do this for a long time, because blackheads are too serious.
