You can go to the plastic surgery department of Xingtai Hand Surgery Hospital. That's where I had the acne pit dermabrasion operation, and the effect was very good. However, if the acne pit is deep, it may take 2-3 times to achieve the desired effect. I have done it twice, and it has been half a year now, and the effect is really good. The charge is only over 2000, which is not expensive.
