Children’s surgical scars, i.e. post-surgical incision scars, cannot be completely removed once they appear, but can be treated with medication, laser therapy or surgery to improve the appearance of the scar. 1. Medication: If the scar is fresh, i.e. it is still in the proliferative stage (3-6 months after the surgical incision has healed), you can usually choose to use topical medication to inhibit the proliferation of keloid scars, such as silicone gel, mucopolysaccharides polysulfate cream, sodium allantoin heparin, and so on, under the guidance of a doctor. 2. Laser treatment: combined laser treatment is also available, such as dye laser treatment in the early stage of scarring, selective occlusion of the local superficial capillaries of the scar to improve the appearance of the scar and inhibit the proliferation of keloid scars; laser beams can also be applied to the skin, which can promote the regeneration of local collagen and rearrangement of the skin to improve the appearance of keloid scars. 3. Surgery: If the scar is obvious and there is no improvement after the above treatments, keloid reshaping surgery may be needed to remove the scar tissue and make tension-reducing sutures. However, surgery is an invasive operation, and there is still a risk of scarring, and it is recommended to use anti-scar medication regularly after the operation. It is recommended that patients who wish to undergo treatment should go to a regular medical institution and follow the advice of a specialist for standardized and scientific treatment.
