What is the long "little red dot"? Perhaps it is the signal of these four diseases.

Skin is the largest organ of the body, the first defense system of the body and a mirror of health. Many diseases can be seen through the skin. Some people find a lot of little red dot on their skin. This is not a simple skin problem, and there may be a major disease hidden behind it.

1, pigmented nevus

Usually, the moles seen by the naked eye are melanin deposits, but sometimes they are red. Generally, moles grow in the skin and accompany people all their lives. However, moles can also become melanoma, which is a kind of skin cancer. If the newly grown or original nevus is larger than 6 mm in diameter, we should be alert to melanoma; Usually, the nevus is round or oval, but the edge of melanoma is irregular and fan-shaped. Under normal circumstances, nevus has only one color, but melanoma presents multiple colors and the colors are irregular and uneven; If you can clearly see the asymmetry of the mole, you need to go to the hospital for dermoscopy to see if it is melanoma.

2. Cherry hemangioma

Cherry hemangioma is caused by local proliferation and is called vascular nevus or red nevus. The color is bright, and it will fade quickly when pressed by hand. Although the name is ugly, it has no effect on the body. However, the cherry hemangioma is enlarged in a short time, so don't be too careless and need to go to the hospital for further examination.

3. Spider nevus

Spider nevus is one of the typical symptoms of various liver diseases, which is shaped like a spider. After the liver is damaged, it will inevitably affect the liver function and cannot inactivate estrogen better, thus increasing the level of estrogen in the blood, leading to the expansion of skin microvessels and causing spider nevus.

4, bleeding point

Little red dot, caused by the rupture of subcutaneous blood vessels, has a slightly protruding surface, which will not fade when pressed, and will disappear in about three weeks. However, there are more and more bleeding spots that do not subside for a long time, so we need to be alert to problems with platelets or blood vessels, which may also be blood diseases.

1, scientific bathing

Winter in the north is cold and the air is dry. Even if there is heating, you should reduce the number of baths, usually once every 2 ~ 3 days. You can't take a bath with too hot water, strong alkaline soap or shower gel. The water temperature is about 37~40, and the bathing time is controlled at 15 minutes. Apply moisturizing cream immediately after bathing to lock the moisture in the skin and relieve the problem of dry and itchy skin.

2, do a good job of cold and warmth.

If you don't do it well in winter, your ears, face, hands or feet will be frostbitten, so wear gloves, earmuffs and scarves when you go out. Wash your hands and face before going out, dry it and apply moisturizing cream to prevent chapped skin.

3, can't use inferior cosmetics

Inferior cosmetics or skin care products contain a lot of heavy metals, which have certain toxic effects on the skin or cause skin allergies, so we must be careful when choosing cosmetics. In addition, carefully remove makeup before going to bed to protect skin function.

skill

Usually pay more attention to small abnormalities on the skin. For the sake of safety, abnormal skin symptoms need to be checked and treated by a doctor immediately without delay. In winter, the weather is cold and there are many clothes, so we are also very particular about dressing, especially the close-fitting clothes. Because the friction between clothes will generate static electricity and irritate the skin, it is best to choose close-fitting clothes such as pure cotton or silk that are not easy to generate static electricity. Drink more water and eat more fresh fruits and vegetables and coarse grains in winter.
