Birthmarks are generally caused by congenital developmental abnormalities, and can be divided into pigmented and vascular types. The common pigmented type includes nevus of Ota, congenital pigmented nevus, coffee spot, etc., while the vascular type includes bright red nevus, strawberry-like hemangioma, etc. There are several methods to get rid of birthmarks as follows: 1. Cryotherapy: using extremely low temperature to induce local cell tissue atrophy or apoptosis, so as to achieve pigmentation reduction effect, the treatment process is relatively short, and the advantage is less pain. However, some patients can form scar or pigment disorder, scar people should be careful to choose; 2, laser treatment: the use of high-intensity beam energy generated by the instrument to destroy the abnormal blood vessels or pigment cells in the skin, so that the pigment particles disintegration vaporization, closed blood vessels, and then absorbed by the body, the pigment is faded. Different color birthmarks will absorb different wavelengths of laser, laser treatment is highly selective for the treatment of birthmarks and generally does not leave scarring; 3, skin grafting treatment: the birthmark will be removed directly through surgery and then the wound will be covered with similar skin, and the birthmark will be removed after the skin is successfully revived. However, the skin used for transplantation is often very thin and the tiny blood vessels are prone to blockage, so there is a possibility that the patient will need multiple surgeries. It is not recommended to consider skin grafting if the birthmark can be removed by laser. Each person’s birthmark is different, so there will be differences in the treatment. It is recommended that after professional consultation and treatment, you should choose the appropriate way to get rid of it according to your situation under the guidance of your doctor.
