How does melanin on the face return a responsibility more?
summary
Pigmentation is the general term for age spots, chloasma, freckles and other skin problems, which can make people look old like wrinkles. Even if there are no wrinkles on the face, as long as there is pigment, the whole face will look dark, giving people a feeling of uncleanness. Pigmentation is usually stimulated by sunlight, ultraviolet radiation or cosmetics, drugs and other substances, which forms the accumulation of black skin pigment. One part is scattered with the stratum corneum; the other part is deposited in the bottom layer and discharged out of the body through blood circulation. Once the above functions are out of balance, it forms pigmentation.
How does melanin on the face return a responsibility more?
The first: heredity, common 18 years old before the appearance of facial spots, may be related to heredity. Due to the environment, air pollution and so on, the ozone layer is broken, and a large number of ultraviolet rays are produced to directly radiate our skin. In order to prevent skin cells from being oxidized, the human body secretes a large number of melanin for maintenance, thus causing pigmentation to form black spots.
Second: food, the nutrition of our skin mainly comes from blood, and whether the nutrition of blood is sufficient and suitable depends on the quality of food. Alkaline substances can neutralize the acidity of meat and cereal foods, make the body fluid adhere to the alkaline environment, dissolve the toxic substances precipitated in the cells, make it excreted with urine, and accelerate metabolism.
Third: cosmetics and skin cleanliness, because cosmetics contain chemicals and lead and other heavy metals, if not properly cleaned, it is easy to cause pigmentation. Photosensitive, long-term sunlight and strong radiation light source will accelerate the synthesis of melanin, resulting in skin darkening. Special physiology and mood, women in menstruation, pregnancy (especially in pregnancy) due to progesterone stimulation.
matters needing attention
If our body presents endocrine disorders, pregnancy, chronic hepatitis and other conditions, our skin will also present melanin. Therefore, whether it is to prevent melanin calm or to prevent melanin calm deepening, we must develop good living habits.
