With the current laser technology, the wart can be cauterized or carbonized, until the scab falls off to get wet, but the time for the scab to fall off depends on the depth of the surgery, usually takes 1-2 weeks. If the wound is red and swollen, it can be treated with anti-inflammatory medication. After the scab is formed, it is recommended to let it fall off naturally to avoid scratching and causing secondary trauma, which will eventually lead to pigmentation or scar formation. After the scabs fall off, there may be localized melanin deposition, which is normal and does not require special treatment, and usually the melanin will fade away on its own after 1-3 months. Laser surgery requires professional skills, so it is recommended to go to a regular hospital to do it. During the post-operative recovery period, pay attention to a light diet, do not eat greasy and spicy stimulating food. If you can touch water, try not to wash your face with cold water or use too much cosmetics, and pay attention to sun protection to prevent UV radiation from aggravating melanin deposition and affecting the recovery effect.
