Scars are medically known as keloid scars, and there is no such thing as the most effective way to remove pigmented keloid scars. Pigmented keloid scars generally do not need treatment, if it affects the aesthetics, the patient can follow the doctor’s instructions to promote the elimination of pigmented keloid scars through medication, physical therapy and other ways. 1. Medication: you can apply vitamin E cream locally, which has the effect of antioxidant and anti-free radicals, and is conducive to promoting melanin metabolism, and you can also use hydroquinone cream and vitamin A cream, which can remove hyperpigmentation more effectively. 2. Physical therapy: laser surgery can be used to remove pigmented scarring, using specific wavelengths of the laser to break up subcutaneous melanin cells and stimulate the repair of damaged tissues under the skin, thus promoting the elimination of scarring. It is recommended that patients go to regular hospitals, choose the appropriate way of treatment under the guidance of professional doctors, do not blindly self-medication.
