Pigmentation includes freckles, dark spots, chloasma and age spots, etc. These spots are of different types and have different causes.

Freckles is a chromosomally dominant hereditary skin disease that is related to our genes. It usually occurs on the face, neck, back of hands and other parts of teenagers.

Dark spots and ultraviolet rays are the primary causes of skin problems. They not only cause wrinkles and sagging of the skin, but also cause stains. Most people will naturally metabolize the melanin deposition caused by ultraviolet rays, but some people with slow metabolism or older people will leave melanin behind and form dark spots. There are also some factors that can also form dark spots, such as trauma, dust, ink and other substances embedded in the wound; use of iodine, violet syrup; cosmetics containing lead, mercury, arsenic poisoning; eating too much food containing pigments, Such as black fungus, soy sauce, etc., which will cause pigmentation and thus form dark spots.

Chloasma is acquired and is more common among women. It is also called butterfly spots and pregnancy spots. This is mainly due to the obstruction of the fine circulation between tissue cells, cell dissolution and death, resulting in the increase of melanin and the formation of stains.

9%-20% of long-term oral contraceptives are prone to chloasma, and some people will develop facial spots after taking them for a month. There are also other drugs, such as those for diabetes and high blood pressure, and highly photosensitive foods, such as carrots, coriander, celery, etc., which can easily cause chloasma.

Androgen and progesterone increase after pregnancy, so chloasma will appear on the face of pregnant women. For most people, after giving birth, the spots will be reduced or disappear after the hormone secretion in the body returns to normal.

There are also some chronic diseases, such as tuberculosis and chronic hepatitis, which can also lead to an increase in melanin, but their own metabolic ability is weakened, so the melanin is not excreted in time, and chloasma will form over time. .

Age spots occur when human cells age, fat is peroxidized, and the skin’s metabolic capacity slowly weakens. Then eat more fresh vegetables and fruits, and take some antioxidant vitamins E, C, B2, cysteine, etc.
