A, “birthmark” can fade on its own, without treatment “birthmark” is a common name, generally after birth in the skin surface color or shape of the abnormal, such as pigmented nevus, Mongolian spot, coffee spot, nevus of Ota, hemangioma, etc.. Liu Zhaoming, director of pediatric plastic surgery at Shijiazhuang Maternal and Child Health Hospital, pointed out that different “birthmarks” have different developmental trends. For example, Mongolian spots, which look like bruises, can fade and disappear with age, but coffee spots do not disappear on their own. For example, there are many types of hemangiomas, among which the strawberry hemangioma part of capillary hemangioma can fade away naturally, while other hemangiomas will have a stopping period, but generally will not fade away on their own. For birthmarks that may fade on their own or are not on the head and face, you can choose to observe them; however, for birthmarks that cannot fade on their own or even develop malignant changes, which seriously affect the beauty and physiological functions, you need to seek medical treatment in time, and the earlier the treatment, the better the treatment effect and the shorter the treatment time required. The earlier the treatment, the better the treatment effect and the shorter the treatment time required. Take hemangioma as an example, it has been in the growth trend for one year after birth, and 3 to 5 months after birth is the rapid growth period. Many parents think that laser is “safe” and often ask doctors to take laser treatment. Director Liu explained that laser is only one kind of treatment method, and it has its own indications, like strawberry hemangioma, coffee spot, etc. The effect of laser treatment is better, but the effect of laser treatment is more general and the number of treatments required is more, like nevus, cavernous hemangioma, etc. For birthmarks, traumatic scars or congenital malformations, it is best to visit a professional plastic surgery department and let the doctor develop a personalized treatment plan based on the type, location, size and growth rate of the disease and the patient’s age, choosing laser or medication, surgical treatment, or a combination of various measures. The doctor will choose the most suitable treatment method according to the overall condition of the patient, and parents should not overly reject surgery. Most moles have no effect on health, but if they are in a special place that affects the beauty, or if the area is too large for giant moles, they can be removed. If the pigmented nevus such as black nevus grows in places that are easy to rub, such as collar, cuff, ankle, etc., then you need to be alert and seek medical attention once the following symptoms change: growth and change of the pigmented nevus in a short period of time, loss of hair on the black hair nevus, appearance of satellite foci around the pigmented nevus, ulceration or hard nodes in the pigmented nevus, color change, pain or itching, etc. Fourth, scar removal treatment is to make the scar not leave a trace at all The scar left after trauma or surgery affects the beauty, and removing the scar without leaving a trace is the purpose of most people doing cosmetic surgery. However, the scar is equivalent to the “glue” that makes the wound heal, and is an inevitable product of the human body’s trauma repair process, so as long as there is a wound, there will be more or less scar existence. As long as preventive measures are taken during this period, such as pressure bandaging, topical ointment or laser treatment, except for those with keloid, obvious scarring can be effectively avoided. If you miss this period and the scar has been formed after trauma or surgery for more than half a year to one year, which not only affects the aesthetics but also may cause dysfunctional activities, you need to go to a regular hospital for treatment in time.
