Melanin removal at the scar is mainly through daily care, topical drugs, laser treatment and other methods. 1. Daily care: usually should pay attention to sunscreen work, to avoid a large number of melanin deposits. Try to apply sunscreen before going out and carry a sunscreen umbrella. In addition, friction stimulation can also induce melanin deposition, so you should avoid too much friction stimulation at the scar. 2. Topical medication: Apply medication that promotes melanin metabolism, such as cumquat cream ointment, hydroquinone cream, etc. You can choose the one that suits you under the guidance of your doctor. 3. Laser treatment: In case of unsatisfactory medication, laser treatment can be chosen. It should be reminded that after laser treatment, you should also do a good job of sun protection to prevent aggravation of pigmentation. If you need to get rid of the melanin at the scars, it is recommended to communicate with the doctor to choose the appropriate method of removal and avoid self-medication.
