Is it easy for a child's skin to turn from dark to white?

Skin is our outer coat. As Chinese people of the yellow race, we tend to prefer fair skin. However, many children appear darker than other children for one reason or another. Fair skin or darker-looking skin are caused by many reasons. Some are due to congenital inheritance. If the parents are dark-skinned, the child may also be darker. Some are due to acquired reasons. So is there a reason for a child's skin to change from dark to white? Let’s interpret it together today!

Darkening of the skin is partly due to genetics and partly due to aging. As we age, melanocyte stem cells will unconsciously secrete melanin. Another part is the uneven secretion of hormones. Uneven hormone secretion comes from different periods of the human body, such as stress, medication, menstrual period and pregnancy. Another part is skin inflammation.

Generally speaking, it is caused by the deposition of melanin. Pay attention to less sun exposure, eat more fruits and vegetables, and drink more water. Tofu and kelp have good whitening effects. If you are really worried, you can go to the hospital to check whether your blood components are normal, especially the number of white blood cells.

The key is to take good protection. Cabbage, onion and radish are very effective in removing melanin. Corn is rich in cysteine, which is rare among foods and is a natural food that can block ultraviolet rays for you. Fruits rich in vitamin C, such as strawberries, kiwis, guavas, tomatoes, lemons, etc., are also natural whitening products.

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.

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. In addition, repeated use of mercury-containing ointments can also leave brown pigmentation on the affected area. There are more anticancer drugs that cause skin color changes.

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.

In the summer, if you still want to have fair and flawless skin, you should do a good job of sun protection, especially when the UV index reaches 7 or above, it is more likely to damage the skin. You should strengthen sun protection and don't be afraid of trouble and cause regret in the future.

In fact, humid air, sunlight coming through car windows, and even indoor light bulbs and computers are all the culprits that cause your skin to become darker.
