Children’s depressed scars can generally be repaired through medication, laser therapy and other methods. 1. Medication: Growth factor gel can be used externally at the early stage of scarring to promote further healing and recovery of the skin, which can improve the degree of depressed scar; however, this method has a long treatment period and needs to be carried out under the guidance of specialized doctors. 2. Laser therapy: commonly used lasers include carbon dioxide fractional laser, erbium laser, etc. This method mainly utilizes the selective photothermal effect of laser to cause thermal damage to the depressed scar, restarting the skin’s reconditioning process in order to stimulate the regeneration and rearrangement of local collagen to improve the appearance of keloid scars. It should be noted that the removal of depressed scars need to go to a regular hospital for an interview, under the guidance of specialists to choose a specific method of treatment, especially children need to be more careful with the use of drugs, avoid blind self-medication to avoid adverse consequences.
