External causes
1.The environment and air pollution cause the ozone layer loopholes to produce a large amount of ultraviolet radiation directly to our skin, and the human body, in order to avoid the oxidation of skin cells, secretes a large amount of melanin to protect, thus leading to pigmentation to form dark spots.
2, food, our skin nutrition mainly comes from the blood, and whether the blood nutrients are sufficient and suitable for cell survival depends on the quality of food, alkaline substances can neutralize the acidity of meat and cereals, so that the body fluid to maintain an alkaline environment and dissolve the toxic substances precipitated in the cells, so that it is discharged with urine, and can accelerate the metabolism, alkaline food: fresh fruits and vegetables, raw garlic, kelp etc.

For pigmentation caused by internal factors are: chloasma, skin dullness, etc. Internal Chinese herbal medicine should be taken as the main treatment. Although “peeling” is popular in many beauty salons today, that is, to make the skin epidermis fall off, it is not a good solution for pigmentation. When the skin cells lose their immune function, the body will secrete a large amount of black spots to protect the damaged cells, and the large amount of cytoplasm will destroy the immunity of the cells, so it will make the pigmentation more serious, so it is not desirable.
Pigmentation mainly lies in prevention, followed by correct treatment.
