freckles are removed and spots appear every year. Many women, especially middle-aged women, are often troubled by problems such as spots and chloasma. First of all, we must understand the factors that cause spots: Five major causes of spots

Genetic factors

Due to family inheritance, in some women, the spot matrix pigment contained in hormones Extraordinary.

Skin Pigment

As melanin gradually increases in the body, it will accumulate in the basal cells of the skin. This melanin is derived from tyrosine, which is oxidized and polymerized under the catalysis of tyrosinase. Its quantity, density and distribution vary greatly among different races, individuals and parts. The face, back of hands, head, neck, and armpits are slightly darker than other parts, indicating that these parts have more melanin. Acid-base imbalance: When the acidity of blood in the human body is high, blood circulation will be weakened, cell metabolism and life function processes will be blocked, and melanin cannot be metabolized normally, causing melanin to gradually accumulate, thus forming dark spots on the skin surface.

Body endocrine

Pigment metabolism is closely related to body endocrine. For example, when women suffer from poor liver and gallbladder metabolism, gastrointestinal dysfunction, or adrenal insufficiency, their skin will become darker. Black; some women will have facial pigmentation due to ovarian dysfunction and physiological cycle disorders; during pregnancy, changes in hormone levels in the body will also stimulate the secretion of melanin.

Mental Stress

Once some women are under heavy mental pressure, their autonomic nervous system function will become imbalanced, blood circulation will slow down, causing skin metabolism to slow down, and melanin will gradually precipitate to form Pigmented spots. For example, when people are under increased psychological stress, they are particularly prone to acne on their faces. The black marks left by the acne will not fade and accumulate under the skin, which will turn into stains.

Pathological factors

Visceral dysfunction, such as lupus erythematosus, chronic alcoholism and other diseases will form stains on the face; chronic gastrointestinal diseases, tuberculosis, and yellow spots will appear on the face. Brown spots; in patients with liver insufficiency, the decomposition of nutrients is incomplete and the skin cannot excrete toxins, which increases the content of estrogen in the blood, thereby stimulating the formation of melanocytes.

Three major misunderstandings

Myth 1. Frequent exfoliation promotes skin breathing

I heard that sometimes the spots on the face are caused by the thick cuticle of the facial skin. , is caused by it, so many people choose to exfoliate regularly, thinking that this will make the skin breathe more freely.

The skin's cutin plays a very important role. It can block sunlight from damaging skin tissue, prevent external toxic substances from invading the body, effectively prevent the invasion of some microorganisms and bacteria, and resist wind, sun, and rain. Wait for external stimulation. If you exfoliate frequently, it will violate the natural metabolism of the skin. After the skin loses the protection of cuticles, it is easy to develop contact dermatitis, and the bacterial infection rate will also increase accordingly.

Myth 2. Homemade facial masks are good for the skin

Many people think that using vegetables or fruits to make homemade facial masks to remove freckles is economical and natural and will not cause any side effects on the skin.

The phenomenon of homemade facial masks is relatively common on university campuses. Many people have misunderstandings and believe that purely natural fruits and vegetables will not be harmful to the skin. Experts believe that certain foods do have the effect of whitening and removing freckles when applied to the face, but in different seasons, the ability of facial skin to resist the external environment will be different. Especially when the seasons change, the skin barrier function will be greatly reduced, and skin allergic reactions are more likely to occur at this time.

Myth 3. All vegetables are welcome

Eating more vegetables is indeed helpful to our body, but some vegetables should still be eaten with caution, such as celery, coriander, white radish, etc. They are all "photosensitive" vegetables. These vegetables make skin prone to spots more likely to develop spots. You should eat more vegetables and fruits that inhibit pigmentation and make your skin whiter, such as kiwi, strawberries, tomatoes, oranges, cabbage, cauliflower, etc.
