The causes of freckles on the nose are: Melanin: The formation of freckles on the nose is mainly caused by the excessive production of melanin by melanocytes in the basal layer of the skin epidermis. Melanin is derived from tyrosine contained in cheese and other foods, and under the action of enzymes in the body, tyrosine is converted into dihydroxyphenylalanine, which is then oxidized and finally polymerized into melanin. If the pituitary gland produces more melanin for some reason, it can cause pigment metabolism disorders and skin freckles.
Genetic factors: Freckles usually appear after the age of 5 years and have a certain genetic predisposition, and women also have more freckles than men due to estrogen. When the sun exposure increases in summer, the color of freckles deepens, which has a greater impact on beauty. In winter, although the freckles are lighter, they do not disappear completely. It has also been observed that people with more freckles also have a higher incidence of pigmented nevi. Intestinal toxins: A normal human body contains many toxins, especially in the intestines. When the autonomic nervous system of the human body is disordered, especially when the parasympathetic activity is weakened, the secretion of intestinal fluid is reduced, the peristalsis of the intestine is weakened, the feces stay in the intestine for a long time, and the toxins are absorbed, and when the content of these toxins is too high, they will be deposited on the skin with blood circulation, thus forming freckles.
