After a child’s forehead scar is formed, it can no longer be completely removed, and can only be improved through self-repair, topical medication, laser treatment and other methods to improve the appearance of the scar as much as possible. 1. Self-repair: keloid scars have a certain developmental pattern, generally 3-6 months after the injury for the proliferation of keloid scars, after the proliferation of keloid scars, the scar tissue will gradually soften and shrink. Therefore, shallow and small scars can be repaired and faded after a period of time, without much special treatment. 2. Topical medication: For early keloid scars in the proliferative stage, topical medication such as Cumexoside Cream Ointment and Mucopolysaccharide Polysulfate Ointment can be used to improve the final appearance of keloid scars through the mechanism of inhibiting keloid scar proliferation. 3. Laser therapy: dye laser, carbon dioxide laser, erbium laser and so on are commonly used in clinic. Dye laser is mainly used for proliferative scar, which can selectively act on the local hemoglobin and make the capillaries in the scar occlude, so as to inhibit the scar proliferation; carbon dioxide laser and erbium laser belong to the exfoliative laser, which can stimulate the local regeneration and rearrangement of collagen. In addition, it can be improved by surgery, but surgery is also an invasive treatment, so the choice should be careful. It is recommended that patients who wish to undergo treatment should go to a regular hospital in time and follow the specialist’s recommendations for standardized treatment.
