Generally, skin grafting is done by surgery, and skin grafting is not needed for small birthmarks. Now, in addition to skin grafting, skin flap can be used for large birthmarks, but the operation time is longer. The birthmark in delicate skin is not easy to remove, and the scar is not easy to heal.

You can choose laser treatment. When laser is used for treatment, abnormal pigment cells or blood vessels in the skin can be destroyed by the heat generated by laser irradiation, without damaging normal epidermal cells and other tissues in the dermis, thus effectively removing pigmentation or vascular lesions without leaving scars.
