Scar growth after circumcision surgery can be improved by fractional laser surgery, cryosurgery and application of medication. 1. Fractional laser surgery: the high energy heat from the instrument can penetrate the epidermal layer of the skin and cause damage to the hyperplastic scars, prompting the skin to reorganize and regenerate, so as to achieve the effect of removing scars. 2. Cryosurgery: Through liquid nitrogen freezing, the cells in the hyperplastic scars will be denatured and necrotic under low temperature, which can achieve the effect of removing hyperplastic scars. 3. Apply drugs: you can follow the doctor’s instructions to use drugs to inhibit scar proliferation, such as Buck’s Silicone Ointment, Shu Scarring Silicone Gel, etc., which can achieve the effect of relieving scar proliferation. Drugs should be used under the guidance of a doctor to avoid adverse consequences. You need to take good care of the wound after circumcision surgery, and you should also pay attention to rest and eat a light diet. If you need to remove the scars, you can go to the hospital and seek professional medical help.
