4hw.com.cn: many Baoma find that their children's skin is a little black after giving birth. But the parents' skin is white, which makes the parents very confused, so what's the reason for the baby's dark skin? Let's follow Xiaobian to learn more about it~
Black skin may be a genetic cause
If the skin color of both parents is black, then the baby's skin is black and normal. Although there is no way to change the congenital conditions, the skin color can be improved through the efforts of the day after tomorrow. Especially for girls, they are very concerned about skin color, so it's important to protect themselves from sun and pay attention to whitening methods.
Black skin of baby may be caused by diet
Some foods are also the cause of skin darkening. Foods rich in copper, iron, zinc and other metal elements have this disadvantage. These metal elements can directly or indirectly increase the quantity and activity of tyrosine, tyrosinase and other substances related to melanin production. These foods mainly include animal liver, kidney, oyster, shrimp, crab, beans, walnut, black sesame, raisin, etc. If the baby likes to eat such food since childhood, then the skin is not strange.
Black skin may be the effect of drugs
Many drugs will also change the normal skin color, such as chloroquine, which has strong affinity for melanin and aggravates the skin color blackness; about 10% of patients taking quinine have blue pigment spots on their faces. Sedatives pose the greatest threat to skin tone, with butterfly spots on the face and neck, and brownish gray, light blue or light purple on the arms. In addition, repeated use of ointment containing mercury can also leave brown pigment in the affected area. There are more anticancer drugs that cause skin color changes. If the baby has many skin problems since childhood, such as eczema, and often uses the above mentioned drugs, then the skin will naturally be darker than others.
Black skin of baby may be affected by natural environment
If the baby often goes out in the sun and doesn't pay attention to the sun protection, then the damage of ultraviolet to the skin is very big, and the skin is also easy to turn black. Because UV can stimulate melanin in skin, induce skin lesions such as freckles, even in cloudy days, UV is still strong. In addition, moist air, sunlight through the windows, even indoor lights and computers can make the skin dark.
The baby's dark skin may be caused by some diseases
Many diseases can change the normal skin color and make it black. Among them, the most common diseases are endocrine system diseases, chronic consumptive diseases, malnutrition diseases and so on. These diseases can make the skin brown or dark brown, especially in the exposed parts such as face, back of hand, joint, etc. or the parts of pressure and friction.
Another example is chronic liver disease, which can cause facial chloasma or darkening around the orbit. In addition, melanin in melanosis patients is also mostly accumulated on the face, especially in the forehead, cheek, back of ear and neck, which is very obvious. If your baby's skin is abnormally black, you must pay attention to it and go to the hospital for examination as soon as possible.
Baby's dark skin may be a skin disease
Black skin of baby may also be skin disease, especially skin disease caused by some food allergies, such as raw onion, raw garlic, chili, pepper, leek, wine, fish, shrimp, kelp, chicken, duck meat, pig's hoof, pig's head meat and other food, can also induce skin allergy, so that rash clumps, and finally leave pigment to make skin black.
Black skin may be the effect of blood circulation speed
Blood circulation speed will also affect the baby's skin color Oh, because whether the blood vessels are rich, how much hemoglobin oxygen content will have a certain impact on the skin color. In winter, the temperature is relatively low, the capillary is easy to contract, at this time, the blood circulation speed will be relatively reduced, and the exposed skin, especially the face, will be white. The skin color of the part with less capillary distribution will be lighter than the part with concentrated capillary distribution. After people exercise, many parts of the body will turn red, which is caused by strong capillary contraction and strong blood delivery.
