Why birthmarks appear
The reasons for this phenomenon can be many and mainly depends on the individual characteristics of the organism (skin type, immunity state). But still there are the most common factors affecting the increased appearance of moles. Let's look at each of them separately.
Heredity. Carefully take a closer look at your older close relatives. It is likely that on their body a considerable amount of such pigmentation may be even located on the same place as yours. Therefore, if, for example, one of your parents has a large accumulation of birthmarks, then, most likely, by the age of 27-30 years you will inherit the same thing.
Ultraviolet. Many people have heard about this, but nevertheless lovers of golden tan do not become less. Therefore, once again, we recall that a long stay under direct sunlight provokes increased production of melanin (which is a component of pigmentation), and therefore affects their number, size and color. Time from 11 am to 5 pm is extremely dangerous for sunbathing.
Injuries. Very often the trauma of at least one birthmark contributes not only to an increase in its size and a change in color, but also causes the growth of new ones.
Hormonal restructuring or disturbances. The adolescent period, pregnancy and treatment with hormonal drugs can also provoke the appearance and disappearance of moles. According to some assurances of scientists, the growth of pigment spots is also possible from x-ray irradiation. A low dose of radiation is harmless to the body. But on our body there are the smallest spots that can not be seen with the naked eye. But these points are already born birthmarks, and X-rays can provoke the growth of any benign or malignant neoplasm.
What to do if there is a dark birthmark
As already mentioned, the appearance of moles is a natural phenomenon for every person. It is worthwhile if the new birthmark has an asymmetric shape, is non-standard colored or very strongly convex. Neoplasms that have fuzzy or lacerated edges are subject to immediate examination by an oncologist. This same swings and those moles, whose shade became black, purple, crimson or spotty. Do not delay the visit to the doctor, so as not to provoke the development of melanoma.
How to prevent the appearance of pigmentation?
If you do not take into account the hereditary factor, then the use of sunscreens with UV filters will significantly reduce the risk of new birthmarks, observance of safe hours for sunburn (and it is better to refrain altogether from it), keep your hormonal background normal, strengthen immunity. The recommendations will help you understand why the appearance of moles is associated. At any slightest suspicion, do not delay the visit to the doctor, because with timely treatment you can prevent unpleasant consequences.
