Why does the skin change color?

What are brown spots on the skin?

The uneven production of melanin leads to the appearance of age spots - it is synthesized by melanocytes, the cells responsible for skin color.

If unevenly colored areas of skin appear on the face, they immediately try to get rid of them. When they form on the back or in places on the body where it is not visible, they are treated quite calmly.

The tactics are wrong - skin cancer - melanoma can be masked under moles and freckles. Therefore, when fresh spots appear, it is imperative to consult about the safety of neoplasms.

The reason for the brown pigmented areas of the skin

Brown spots on the back, face, and limbs - all over the body - can form for the following reasons:

What are brown spots on the skin?
  • after traumatic injuries - scars, bruises, burns - the affected skin areas can become the same color as the rest of the skin on their own, but sometimes cause a lifelong change in pigmentation;
  • intense exposure to ultraviolet radiation negatively affects the quality of the skin - the body, trying to protect itself, actively produces melanin, and the tan does not always lie flat;
  • hormonal disorders often lead to changes in pigmentation;
  • age-related changes;
  • causes the appearance of spots, taking certain medications or neglecting the recommendations given in the instructions for use of the medicinal product. Very often the instructions indicate: When taking the drug, you should avoid ultraviolet radiation. But who reads the instructions carefully?

If the adrenal glands are disrupted, light brown spots not only worsen the cosmetic appearance, but also cause significant discomfort - they flake off, causing itching.

Additional symptoms of the disease are: mood swings, tearfulness, sleep disturbance, muscle fatigue at rest and soreness after exertion.

There are many diseasesand conditions for which hyperpigmentation is a symptom.

Hyperpigmentation as a symptom of pathologies

Let's look at the most common diseases in which the skin changes color unevenly:

What are brown spots on the skin?
  1. Avitaminosis - the body reacts to a lack of vitamins A, C and PP.
  2. Brown spots on the legs are formed due to trophic disorders that are caused by insufficient blood circulation. The most common diseases that cause uneven hyperpigmentation on the legs are atherosclerosis obliterans and diabetes mellitus. Dark spots indicate vascular changes. New growths that appear on the legs are often injured - when shaving or careless movements. This increases the possibility of the neoplasm degenerating into a malignant form.
  3. With age-related changes, small spots of light brown color cover the surface of the skin exposed to solar radiation. Pigmented rashes are localized on the back of the hands, forearms, upper chest and neck, legs below the knees.
  4. An intense increase in facial pigmentation causes pregnancy. There is even a medical term - Pregnancy mask . The spots are localized under the eyes and around the mouth, on the cheeks. In summer, mask is of a darker saturated color - pale in winter. Brown spots on the face caused by pregnancy disappear 2-3 months after childbirth on their own, the condition does not require treatment.
  5. Dermatological disease - versicolor or pityriasis versicolor, is also characterized by this symptom. An area with sharply defined boundaries appears on the skin, which is different in color from the main skin. If the sick person is exposed to the sun, the color of the focus becomes dark brown. The foci do not rise above the surface of the body, but the structure of the epithelium on them may differ from the surrounding tissues - the skin becomes denser and may begin to peel off.
  6. Not very large rashes, localized in bulk, may turn out to be ordinary freckles. Their number and intensity of color increases in spring and decreases in autumn. When sunburned, the spots compare in color with the surrounding tanned skin. It is impossible to notice any discomfort when freckles appear.
  7. In Recklinghausen's disease or neurofibromatosis, first light brown spots with fuzzy outlines appear on the body. After a while, in the area of ​​the appearance of pigmented areas, you can already feel the nodules that are soft to the touch - they stand out against a dark background, as they are pink. This sign indicates that the inflammatory process has already begun at the level of the bone tissue.
  8. Pigmented xeroderma - the disease begins with phytodermatitis, then brown spots merge with each other. The disease can cause instant malignancy, but in one of its forms - Jung's xerodermoid - it takes up to 20 years before epidermal cells degenerate into melanoma. If the sick person observes medical recommendations - avoids contact with natural ultraviolet light or artificial radiation, the rebirth can be stopped.
  9. Black acanthosis. First, dark, almost black spots appear in the area of ​​natural folds, then they bulge and thicken. This condition indicates that a malignant process has already begun in the body. Thanks to such a marker, sometimes degeneration in organs or systems can be stopped at the very beginning, preventing the stage at which metastases appear.

When pigmented areas of the body appear, it is recommended to start cosmetic procedures only after a complete examination, finding out the reasons that caused the hyperpigmentation.

Treatment or elimination of age spots

If a change in the condition of the skin is caused by diseases of various etiologies, then the disease must be treated with medical means. Lightening of spots is carried out only after it has been found out that pigmentation is not dangerous for health.

  • moxibustion with liquid nitrogen - the superficial epithelium dies off, the new skin has no defects;
  • chemical peeling - the same principle of the procedure;
  • photorejuvenation - several sessions are performed in which cells that intensively produce melanin light up .
