Laser can selectively act on different skin tissues. As long as a specific light source is used, it can ensure that it only acts on pigmentation and does not affect normal skin tissue. Laser energy can be absorbed by pigment particles in the focus in a very short time, resulting in extremely high temperature, which makes it expand rapidly, form micro-explosion, crush into tiny particles, and then be swallowed up and removed by macrophages in the tissue.

Keep the treatment area clean and dry, and do not touch water before local scab to prevent infection.

After half a month to half a year of treatment, we must do a good job in sun protection. Apply suitable sunscreen indoors and strengthen sun protection outdoors.

In general, the younger the age, the thinner the skin, the shallower the lesion, the stronger the repair and absorption ability, and the less the number of treatments, the better the treatment effect.

Laser treatment of pigmentation requires multiple treatments. Generally, chloasma needs about 5 times, coffee spot needs 1 ~ 3 times, and senile plaque needs at most one time. The interval between each treatment is about 2 months.

It is not advisable to do strenuous activities and make-up before the scab falls off, and do not tear off the scab forcibly. Some patients may have pigmentation, and most of them will disappear within a few months.

Both doctors and patients should protect their eyes during the treatment. Laser treatment of pigmented lesions will not cause irreversible harm to the body.

Try to go to a regular professional hospital and choose a qualified professional doctor for treatment to ensure safety and effectiveness.
