Laser freckle treatment is safe and does not leave scars after treatment. The treatment process is quick, there is no bleeding, and no special medication is needed after treatment. As long as the treated part is kept dry and clean, it can be cured in 5-7 days without affecting life and study. Laser can only remove the existing pigment, but it can't prevent it from reappearing. Therefore, after laser freckle treatment, we should pay attention to the doctor's advice to do a good job of nursing, such as avoiding sun exposure, which can prevent adverse reactions to the maximum extent.
