Why does a woman's white skin turn darker?

Nowadays, popular boys are tall, rich and handsome, while popular girls are fair, wealthy and beautiful. Doesn’t fair mean having fair skin and good looks? So it seems that being fair is also a very important thing for girls. If you used to have fair skin, but one day you looked in the mirror and found that you had become darker, what happened? Today let’s talk about the reasons why fair skin turns dark.

1. The foods you like are rich in zinc, copper and iron.

Certain foods are also the cause of darkening of the skin. Foods rich in metal elements such as copper, iron, and zinc have this disadvantage. These metal elements can directly or indirectly increase the amount and activity of substances such as tyrosine and tyrosinase that are related to melanin production. These foods mainly include animal liver, kidney, oysters, shrimp, crab, beans, walnuts, black sesame, raisins, etc.

2. The drug has affinity to melanin.

Many drugs also change the normal skin color. For example, chloroquine has a strong affinity for melanin, which aggravates skin discoloration; about 10% of patients taking quinine develop blue pigment spots on their faces. Sedatives pose the greatest threat to skin color. Those who take them for a long time will develop butterfly spots on their face and neck, and their arms and other parts will turn brown-gray, light blue or light purple.

3. The natural environment damages the skin.

The culprit is ultraviolet rays, which stimulate the melanin in the skin and induce skin lesions such as freckles. Even on cloudy days, the ultraviolet rays are still strong. Ultraviolet rays can cause skin darkening, aging, and wrinkles.

Human skin's response to ultraviolet rays causes redness, tanning and increased thickness of the skin's epidermis in acute reactions, and leads to skin aging in chronic reactions.

4. Certain diseases are triggering factors.

Many diseases can change the normal skin color and make it darker. The most common ones include endocrine system diseases, chronic wasting diseases, malnutrition diseases, etc. These diseases can cause the skin to turn brown or dark brown, which is particularly obvious in exposed areas such as the face, back of the hands, joints, or areas that are under pressure and friction.

Another type of disease is skin diseases, especially skin diseases caused by allergies to certain foods, such as raw onions, raw garlic, peppers, peppers, leeks, wine, fish, shrimp, kelp, chicken, duck, pig's trotters, pig's head and other foods, which can also induce skin allergies, resulting in rashes and finally leaving pigments to make the skin darker.

The above discussed the reasons why fair skin turns darker from various methods. I believe that if your skin turns darker, you will be able to find the reason. Only by finding the reason can you come up with targeted countermeasures. For girls who want to have fair skin, you must pay attention to sun protection and isolation, take good care of your skin, and eat less food containing zinc, copper, iron and food that makes you allergic.
