Most birthmarks can be removed, and patients can be treated according to the type of birthmark. Birthmarks are pigmented lesions that appear on the surface of the skin due to abnormal proliferation of skin tissues during the developmental period, mostly on the back, buttocks and sacrum, head and face, and other parts of the body. Some birthmarks will fade away on their own after birth, and usually do not require special treatment and observation. If the birthmark grows on the head and face, affecting aesthetics, growing rapidly, or accompanied by itching, pain, bleeding and other symptoms, it should be promptly consulted. For smaller capillary hemangiomas and cavernous hemangiomas, sclerosing agents can be used, such as 5% sodium cod liver oil acid solution or 1%~10% sulfate solution, etc. Glucocorticosteroids, such as prednisone and triamcinolone suspension, can also be used for injection treatment. The above drugs should be used according to the doctor’s prescription. Physical treatment can also be carried out through liquid nitrogen freezing, laser treatment, chemical peeling, skin grinding, etc. If the birthmark continues to increase in size, broken, bleeding, etc., surgical treatment can be considered. It is recommended that patients who need to remove birthmarks go to the hospital in time, under the guidance of the doctor to standardize the treatment, do not do it on their own.
