During laser speckle removal, the patient will have a needle-like sensation, but most people can tolerate it without the use of anesthetics. The operation time with the laser does not need to be too long, generally less than ten minutes. The skin can return to normal within 7 to 10 days without affecting people's normal life. After each operation, the skin must have a natural absorption process, so the interval between operations is generally 2 to 3 months. Depending on the size, number and depth of pigmented spot lesions, some operations can achieve the desired effect once or twice, but generally it takes 4-6 times to completely resolve.

The main precautions after laser spot removal are:

1. After laser speckle removal, it is normal for the skin to be red and swollen due to the irradiation of laser energy, and sometimes there will be some slight bleeding, but it will subside quickly.

2. After laser spot removal, the redness, swelling and anti-inflammatory can be appropriately removed according to the skin condition. The wound will slowly form a scab, and the scab can be removed in about a week. Temporary skin erythema or hyperpigmentation may appear at the site of the operation, but this phenomenon will gradually subside and return to normal later.

3. Pay attention to keep the operation part clean and avoid sun exposure. The operation part is very sensitive to sunlight, try to use sunscreen or umbrella to improve the operation effect.

4. After laser speckle removal, you should adjust your diet appropriately, and avoid spicy and stimulating foods, such as pepper, ginger, raw garlic, soy sauce, etc.

5. Maintain emotional stability and develop good living habits to avoid endocrine disorders and stimulate pigmentation.
