What the scars of the skin can tell
The scars on the skin are different – some of them are harmless, while others – not so much. Moles, and spots of birth, which have a common name nevi, occur on the skin where there is accumulation of cells that produce melanin – dark pigment. Where will mole, what will be their color and size of certain genes. Moles are not as harmless as they seem at first glance, because in theory at least each of them can be “reborn” in melanoma. Pigmentation may be of different shapes and sizes. They occur more frequently in women as a result of radiation or sunburn. There are other reasons for their occurrence: pregnancy, application of creams, which are not suitable for your skin. Pigmentation is more common in people with olive skin and black hair. Freckles are also pigmented spots, but yellow-brown. The reason for their occurrence is melanin. The most commonly encountered in speckle white people with light hair. Most of them occur at 3-4 years of age, developed mostly in the skin of the face and are particularly noticeable in the sunshine. At about the age of 40 of them begin to disappear. They do not harm health and the removal is justified only cosmetic purposes. White spots (vitiligo) are contrasted with moles and occur on those areas of the skin with no melanin. Not yet discovered regularities in their appearance and location.
They are considered a cosmetic defect, but has recently conducted experiments have shown that blood plasma of people suffering from vitiligo, introduced into experimental animals leads to progressive loss of skin pigmentation. From these spots can be saved by medical means or to hide them with cosmetics.
