The medical term for a facial birthmark is a spot or mole, which is an abnormal proliferation of skin tissue during development and appears as an abnormality in shape and color on the skin surface. It can be present at birth or may surface slowly after a few months of life. Facial birthmarks can be divided into pigmented type and vascular type. The common pigmented type includes Ota spot, congenital dark pigmented nevus, milk coffee spot, etc., while the vascular type includes wine stain, strawberry hemangioma, etc. The incidence of facial birthmarks in newborns is about 10%, which can be said to be very common. Most of the facial birthmarks only affect the aesthetics and do not need special treatment. However, some birthmarks can be combined with abnormalities of body organs and even have the possibility of malignant changes, which must be treated actively. For example, some sponge-like hemangiomas that grow too fast can cause limb disfigurement, which not only looks bad but also causes functional impairment. Even if the hemangioma expands too fast, it can lead to tissue necrosis and excessive consumption of platelets, resulting in low blood clotting and excessive bleeding. Some giant moles with hair growth may later develop cancerous changes of malignant melanoma, and the cancer cells metastasize and lead to death. Because the facial birthmark grows on such an obvious part of the face, it is particularly disturbing. Some people wear heavy makeup every day to cover it up, while others have low self-esteem and are socially reticent. Facial birthmarks are also prone to be looked at differently by others, which can cause facial birthmark sufferers to suffer a great deal of psychological damage; especially children, who are more likely to develop low self-esteem or autistic tendencies in the process of growth. According to research, facial birthmarks can affect the psychological development of children and lead to personality development disorders later on. The black birthmark on the face, which is likely to be a black hair mole, is less effective with laser treatment because the hair follicles are located deep, which is difficult to be destroyed by laser, and is usually treated by direct surgical excision, or excision followed by skin implantation. The current treatment methods are surgical excision, laser treatment, drug injection treatment, etc. All of them have different indications, and advantages and disadvantages. In summary, we also have a more detailed understanding of facial birthmarks. It is recommended to go to a regular professional hospital for consultation and treatment in order to get better treatment results.
