Why do people have moles on their faces?

Pigmented nevi are incidental abnormalities caused by the movement of pigment cells from the neural crest to the epidermis, and are developmental malformations. It is autosomal dominant and is also related to ultraviolet radiation, and can be removed with high laser frequency.

The reason why moles grow on the face may be caused by prolonged exposure to the sun, or it may be caused by diseases such as pigmented nevi and vascular nevi. It is necessary to go to the hospital to check the specific ** and then carry out ** rubber fibrillation.

One. Non-disease ** element:

Exposure to the sun for a long time: If you are exposed to the sun for a long time, there will be **melaninosis, and the diameter of the mole is relatively small, which will not be accompanied by other obvious discomfort.

Two. Disease ** element:

1.Pigmented nevus: In the early stage of the disease, patients will have a macule on the face, and the diameter is relatively large, no more than 6 cm, the color is usually brown or black, and it is not accompanied by other obvious discomfort, such as pain, itching, etc.

If the diameter of the pigmented nevus is small, it can be removed by laser **, and if necessary, it can be improved by hand resection.

2.Vascular nevi: May be associated with vascular malformations, where patients develop nodular growths on their faces, often red in color, and may rupture if left unprompted**.

Patients can be improved by laser therapy at an early stage, and surgical resection can be performed in severe cases.

3.Other diseases: Moles on the face may also be related to black hair moles, there will be black hairs in the middle of the mole, and the diameter of the mole is relatively large, you can go to the hospital for ** endoscopy, ultrasound examination and other related examinations to confirm the diagnosis.

During the period, it is necessary to take protective measures, avoid water before the wound is not completely healed, recheck regularly, and if there is an abnormality, it can be found in time.

There are many causes of facial moles, including genetic factors, sun exposure, long-term irregular work and rest, irregular diet, mental stress, trauma, endocrine disorders, pH imbalance, and vitamin deficiencies.

Among them, genetic factors mean that if the parents have more pigmented nevi, the probability of the next generation will also increase. Sun exposure can cause a damage to the barrier, causing melanin to build up on the face. Long-term irregular schedules can lead to hormone levels that are out of balance, causing an overproduction of melanocytes in the body.

Irregular diets, stress, and endocrine disruptions can also cause melanin to build up on the face.

In addition, pH imbalances and vitamin deficiencies can also lead to moles on the face. Long-term lack of sun protection, especially in boys, who do not wear sunscreen or a sunhat in the sun, may be exposed to direct ultraviolet rays, which is also a possible cause of moles.

In short, moles on the face may be the result of a combination of factors, it is recommended to pay attention to sun protection, adjust work and rest, and maintain a balanced diet on the stool to maintain good health, and it can also be targeted according to the cause**. If the number of moles is large or the shape changes, it is recommended to go to a regular hospital for treatment.

There are cells called melanocytes on the human **, which can produce melanin. Moles are formed by the clump of these melanocytes coming together. Specifically, the formation of moles may be related to factors such as genetics, Pysen UV exposure, hormone levels, age, etc.

Some people are born with moles, while others develop moles as they age. In addition, long-term exposure to the sun may also lead to the growth of more moles on the **. If you feel uncomfortable with a mole or notice a change in its color, size, shape, you should consult a doctor in time to prevent problems such as **cancer.

A mole is a pigmented lesion that is usually caused by an excessive accumulation of melanocytes (i.e., pigment cells) in the body. This aggregation can be due to genetic or natural factors, or it can be due to factors such as sun exposure, changes in hormone levels, chronic friction, etc. Most moles are benign in most cases, but malignant transformation may occur in some cases, so if you observe any unusual mole changes, you should consult a doctor.

Moles are found on everyone's body and face, some grow in places that are easy to see, and some grow in places that cannot be seen. Moles are generally known as a small black dot on the **, it can be large or small, the color is black, cyan and red, some moles are born, and some moles are caused by some factors. Moles don't think it's a big thing, some moles may reflect some diseases of the body, so why do moles grow on the face?

1. Moles are very common

There will be some moles on our body more or less, big or small, which is a very common phenomenon, black moles are the melanin reflection on the **, which is composed of some melanin cells in the dermis, the location of the mole is different, and its name is different, it is divided into moles on the table, that is, the demarcation nevus, as well as dermal nevi and compound nevus, among them, the junction nevus is a more active mole, it is easy to malignant.

2. It may become malignant

A mole is a benign tumor that occurs on the **, which is generally not malignant, but there are also cases of malignant transformation, and the probability of malignant transformation is 1 in 500,000. If you find that the nevus is slowly expanding and darkening, it will often bleed and hurt, then it is best to go to the hospital for examination.

3. Don't mess with moles

Many girls feel that some moles on their faces will affect their appearance, but some moles cannot be messed up, and some moles grow on nerves, which may cause bad consequences once they are wrong. Mole spotting is also risky, it will leave a scar or will also **, so you need to be cautious about mole spotting!
