For acne scars, the best solution currently is Fraxel laser. But this technology has been developed in the United States for 5 years, and it is still not available in China. I believe it will be soon!
Beijing Badachu Plastic Surgery Hospital has mechanical grinding technology, but its anti-black rate is high.
The ‘MOSAIC’ laser invented in South Korea and the Fraxel laser in the United States are both aimed at anti-blackness effects after surgery.
Every time you do it, the acne scars can be healed by about 30%. It is also the best way to treat acne scars in the world.
