Laser surgery is based on the principle that a laser releases high-energy photons that effectively penetrate the skin and act underneath the skin, creating a precise photocutting effect that allows the tissue to function as a vaporizer. This method is a minimally invasive surgery with small wounds that do not harm other parts of the skin. 1. Laser excision surgery is most commonly used for diseases of the superficial organs of the body, such as skin diseases and eye diseases. Skin diseases such as warts, pigmented spots, moles, tattoo removal and other eye diseases such as retinal detachment. 2. After laser removal surgery, you should also pay attention to avoid spicy and stimulating food, eat a light diet, drink more water, and try not to go out.
