Age spots are also called seborrheic keratosis, the cause of which has not been fully clarified. 37 years of age, age spots are considered to be related to heredity, sun exposure, chronic inflammatory stimulation and other factors. 1. Heredity: skin discoloration belongs to autosomal inheritance. If the elders in the family develop age spots at a very early age, their children may also develop this condition under the influence of hereditary factors. 2. Exposure to sunlight: Skin pigmentation is directly related to sunlight. People who are often engaged in outdoor work, such as farmers, construction workers, or those who like to go on excursions, usually do not pay attention to the sun protection of the skin, and long-term ultraviolet irradiation will lead to aging of the skin, which is prone to the appearance of age spots. 3. Chronic inflammation stimulation: frequent local scratching and stimulation may accelerate the formation of melanin, leading to melanin precipitation and easy appearance of age spots on the skin. Seborrheic keratosis in 37-year-old women is recommended to go to the dermatology department of the hospital in time. If you feel that it affects the aesthetic appearance, it is recommended to combine with the doctor’s advice, through surgery, freezing, laser and other ways of treatment.
