As the saying goes: one white covers three ugly. It is every girl's dream to have white and tender skin like snow. However, every morning when I look at myself in the mirror whose skin color is getting darker and yellow, is the mood of the day broken? Do you know what is destroying your white dream? Let's look at the killers who make your skin black.
1. Black skin caused by food
If you eat inappropriate food in your life, be careful that your skin will get darker and darker!
Foods rich in copper, iron, zinc and other metal elements can directly or indirectly increase the quantity and activity of tyrosine, tyrosinase, DOPA quinone and other substances related to melanin production, so they often become the bane of skin melanosis. This kind of food mainly includes animal liver, animal kidney, oyster, shrimp, crab, beans, walnut, black sesame, raisin, etc.
Secondly, healthy body fluids are weakly alkaline. If you take in too much acid substances at ordinary times, it will bring a variety of discomfort to the human body and promote the formation of skin pigment spots. Carrots, spinach, purple turnip, purple cabbage, mushrooms, black fungus, etc. these vegetables make the skin that loves long spots grow more easily.
2. UV promotes melanin
As for the term melanin, we should all be familiar with it. The excessive production of melanin in the skin is a big killer that makes it difficult to whiten the skin, and the biggest reason for the large production of melanin is ultraviolet.
If people with fair skin don't pay attention to sun protection, long-term exposure to ultraviolet light will make the skin form melanin. After precipitation, it may cause darkening and color spots, and the skin color is not white.
Therefore, we must do a good job of sunscreen in our daily life. No matter it's cloudy or sunny, we should apply sunscreen to the skin to prevent the formation of melanin.
3. Skin moisture deficiency
In daily life, computer radiation, air conditioning and skin aging will cause skin dryness, resulting in skin quality decline, resulting in skin darkening.
Skin whitening and moisturizing have always been closely linked. Only when the skin is hydrated can it present a fairer luster. However, the skin with insufficient water has poor metabolism ability, which leads to the decrease of skin repair function and dark skin.
4. Disordered work and rest
Irregular living habits are not only bad for your health, but also make your skin black!
During the sleep time at night, the skin is in the best repair state. Only guarantee good sleep, can make skin metabolism more smooth, skin more whitening. Bad rest and insufficient sleep not only affect health, but also slow down skin blood flow, constrict blood vessels, blood stasis, and make skin gray and black.
Lack of sleep will affect the water locking function of the skin and cause serious water shortage of the skin. At the same time, due to the lack of oxygen supply, the skin will suffer from poor nutrition, resulting in local pigment accumulation, drying and blackening.
5. Love to take a bath
Some people like to rub their skin hard when they take a bath, thinking that they can wash it more cleanly. However, too much force or repeated rubbing will cause the skin to turn black, which is called "friction blackening".
The relationship between blackening of skin and improper bathing has been confirmed by relevant experts. It is mainly caused by mechanical stimulation such as strong friction and compression of local skin. It mostly occurs in people who rub bath towel or chemical fiber bath towel hard, mainly showing the pigmentation from light brown to dark brown.
6. Aging of cuticle
Our skin has a layer of cutin, which is like a double-edged sword. It is not only a protective film to help protect the skin from external damage, but also because of aging or residue on the skin, causing our skin dark and dull.
Because of the long-term exposure of modern people to ultraviolet and computer screen radiation, combined with the pollution of the external environment, the aging of the cuticle is accelerated, resulting in dark skin color and rough skin.
Therefore, at ordinary times, we must do a good job of isolation and sunscreen, and at the same time, we should supplement the anti-oxidation ingredients to the skin, and eat more vitamin rich foods, so as to prevent the excessive aging of horniness.
7. Drug action
Many drugs can change the normal skin color, such as adipine can make the skin color orange; chloroquine has strong affinity for melanin, which aggravates the skin darkening; about 10% of patients taking quinine have blue pigment spots on their faces.
Among the sedatives, chlorpromazine is the most dangerous to the skin color. For long-term users, butterfly spots appear on the face and neck, and palm grey, light blue or light purple appear on the arms.
In addition, repeated use of ointment containing mercury can also leave brown pigment in the focus. Among the anti-cancer drugs, there are more drugs that cause skin color changes, such as malilan, bleomycin, melanin accumulation, etc.
