What causes dark spots on the face?

We often see that many female friends have increasing dark spots on their faces. Sometimes some hairs will appear in the middle of the blackboard, forming what people often call moles. Many reasons may cause black moles on human skin, and some black moles will seriously affect human health. Let us learn about some common reasons that may cause black moles on people's faces.

In fact, the exact cause of some moles is not very clear. However, moles can bring both good and bad news to your health. A mole is medically called a nevus cell or melanocytic nevus, which is a skin manifestation caused by an increase in melanocytes in the epidermis and dermis. If the rash is higher than the skin surface, has a dome-like or nipple-like appearance, or has a pedicle, it is clinically called an intradermal nevus; those that are slightly higher than the skin surface are mostly mixed nevus; those that are not higher than the skin surface are junctional nevus.

Moles are made up of pigment-producing cells called melanocytes, so many moles are different shapes and colors of brown, and some are even skin-colored. It was flat at first, then gradually bulged. In the first 20 years, they will continue to grow, most of them very slowly, some grow to about 1 cm or larger; some grow very large and grow hair. Some children are born with large moles, and some people have more moles than the average person. Moles are more commonly seen in people with fair skin.

Appearance of moles: There are flat black moles and red moles caused by proliferation of microvessels. What to do with a mole? In the past, many doctors often recommended removing moles because some moles have the risk of becoming cancerous. Observation of moles is now recommended. If you want to remove it, there is only 1 good reason...it will rub against your clothes and be uncomfortable. Don't remove it just because it affects your appearance. Unnecessary removal can cause significant scarring, especially on the back, shoulders, chest and calves, which are areas prone to severe scarring.

Pay special attention to the following situations:

1. Remove the hair from the mole. Some larger moles may have hair growing on them. Hairy moles are not at high risk of developing skin cancer, and there is no danger in removing the hair from moles. You can safely shave or pluck them out. Be careful, as these practices can irritate the hair follicles, leading to infection, pain, and swelling. If you experience any of these symptoms, you should see a doctor.

2. Changes in moles: If you have a large number of moles, you must pay more attention and ask your family or doctor to check the changes in moles regularly. Keep in mind their size and location, and while not all changes are bad, they are worth paying attention to. About half of skin cancers develop from long-standing or pre-existing moles, and the other 50% occur on normal skin.
