Laser method: principle, burning fat with laser. Cut a small hole in your eye first, and then burn it. It smells burnt. The pain is obvious, so anesthetic is necessary. The advantage is no bleeding. But when the eyes are stimulated by strong light, because the laser can't rotate, it can only burn the surface, but not the deep layer. Therefore, the big bags under the eyes can only be changed into small bags under the eyes, which is easy to relapse and has no wrinkle removal effect. Price 1 000 yuan, valid for 3 years.
