Is it good or bad to have a birthmark on your knee?

Whether it is a good thing or a bad thing to have a birthmark on your knee is also related to the size, shape and position of the birthmark. Generally, the birthmark of delicate skin is difficult to remove (such as facial skin) and the scar is difficult to heal. Skin grafting is difficult to find the same delicate skin parts of the body. If the area is small, skin grafting is not needed. If the area is large, there are other techniques besides skin grafting, called skin flap.

Whether having a birthmark on your knee is a good thing or a bad thing doesn't mean anything. The reason is that the proliferation of skin tissue will increase with age during development.

Birthmarks with different shapes, sizes and numbers on the back and buttocks are caused by the accumulation and deposition of special pigments in dermal cells. According to the comparative study, this is a special symbol of the descendants of China, neither white nor black. With the growth of children's age, the pigment deposited by cells in the dermis gradually decreases and will fade by itself. About 2 years old, completely disappeared, but a few can be partially preserved for life. Will not bring adverse effects on health and development, because the part is hidden, does not affect the appearance, and does not need any treatment measures.

Red birthmarks are more common in the back of the head and face of newborns, especially above the eyelids. They are red or orange patches. Careful observation also reveals that there are many tiny blood vessel shadows inside. There are two kinds of them, one is called orange spot and the other is called port wine spot.

Orange spots are similar to green birthmarks, and can disappear by themselves after a few months of birth. The red spots under the round hairline are wine spots. The plaque does not protrude from the skin and fades after being pressed with your fingers. When children cry, nurse or shout, plaques are more obvious or reappear because of facial congestion. This is caused by local subcutaneous telangiectasia, which is related to family genetic factors. Generally speaking, nevus flammeus will affect the appearance, but fortunately, the circular plaque is very small, close to the hairline and will not fade immediately. Hair and bangs can also be covered when you grow up, and it will not affect your appearance. Don't worry.

In rare cases, a child's birthmark is related to physical illness. For example, a large nevus flammeus usually occurs on one side of the head, face and neck, and gradually increases within 1 year, often coexisting with cavernous hemangioma of trigeminal nerve, and sometimes meningeal hemangioma and congenital nervous system malformation may also coexist. When the child's skin has many persistent large-scale bruises and unexplained convulsions, it is necessary to consider the possibility of some special diseases with skin and nervous system abnormalities as the main manifestations.

There are several ways to remove birthmarks: 1, laser positioning: only effective for pigmented skin.

Laser localization, accurate localization, only absorbed by diseased tissue. At the same time, the system has a strict self-checking mechanism. When any minor treatment error is found, the computer will automatically shut down the treatment system, so that normal tissues will not be injured by accident, thus leaving no scars and ensuring that the treatment is carried out in absolute safety. The effect of laser treatment of birthmarks in children is obviously better than that in adults.

2, dynamic cooling: no pain at all

Special dynamic cooling device, the laser emitted is scanned after special cooling treatment, and the treatment is like the feeling that a rubber band bounces on the skin, and it doesn't hurt at all.

3. No damage to normal tissues

Laser treatment of birthmark without scar is to use instruments to generate high-intensity beam heat, destroy abnormal pigment cells or blood vessels in the skin, disintegrate and vaporize pigment particles, seal blood vessels, and then be absorbed by the body, and the pigment will fade. Because the laser of a certain wavelength is only absorbed by the pigment of the corresponding color, only the diseased cells absorb the specific laser, and the normal skin tissue is not damaged, so there is no scar left.
