Where does a person get freckles?

Freckles are small yellow pigmented spots on the skin that appear mainly on the face, hands, but sometimes on the torso. Freckles are caused by the presence of a dye called melanin in human skin.

They occur mainly in redheads and blonds and much less often in brunettes. The color of freckles (the color of melanin in them) can vary from a light tan to a dark brown, depending on sun exposure and heat. In addition, the sun's rays can provoke the appearance of new hemps. Freckles are often hereditary, but the genes responsible for freckles have not been identified.

They usually appear in children at the age of 5-6 years, and after 30 years their number decreases; in winter they turn pale, with the onset of summer they darken. If the baby suffers from congenital hypersensitivity to ultraviolet rays, already in the first years of life, under the influence of sunlight, inflammatory redness appears on his skin, turning into pseudofreckles, which require special treatment by a dermatologist.

Freckles are the centers of concentrated tanning, or a kind of protection that protects the most important parts of the body from unbearable light irritations. They appear in pregnant women in strictly defined places: on the face, mammary glands and along the midline of the abdomen, protecting the expectant mother from radiation.
