Laser spot removal usually does not produce scars, because the principle of laser spot removal is selective photothermal effect, through the skin to act directly on the pigment of the skin, and there is no damage to the normal skin tissues, so normal laser spot removal usually does not produce scars. However, these prerequisites are that the apparatus for removing spots should be chosen correctly, the treatment parameters and energy settings should be reasonable, and the laser physician should have enough experience in treatment to meet the above conditions, and the laser removes spots usually without scars. However, if some lesions are deeper and reach the dermis layer of the skin, for example, some seborrheic keratosis, the grinding and peeling treatment of laser may be used, and there may be scars in this case, which mainly depends on the depth of the lesions, and if they reach the dermis layer and destroy the basal layer of the skin, there will be the possibility of producing scars. So the usual spot removal treatments, like including freckles, nevus of Ota, coffee spots, chloasma, etc. usually do not leave scars.
