Skin pigments can be roughly divided into two categories: one is produced by the body, called endogenous pigments; the other is external, called exogenous pigments, which mainly come from drugs, food and foreign objects. There are many colors of pigmentation, including blue, gray, etc., but dark brown is the most common. The causes of pigmentation vary, but they can be summarized as follows:

1. Genetic factors: Representative diseases include freckles, seborrheic keratosis, neurocutaneous melanosis, and pigmented intestinal polyposis syndrome. The pigmentation of this group of diseases is localized.

2. Metabolic factors: Wilson's disease, hemochromatosis, etc. Pigmentation is mostly systemic and diffuse, with no obvious boundaries.

3. Endocrine factors: Addison's disease, certain pituitary tumors, long-term estrogen treatment, pregnancy and melasma, etc.

4. Malnutrition: kwashiorkor, pellagra, vitamin B12 deficiency, etc.

5. Chemical and drug factors: certain anti-tumor and anti-immune drugs, anti-malarial drugs, tar, asphalt, anthracene oil and other hydrocarbons.

6. Physical factors: mechanical trauma, ultraviolet rays, certain radiation, chronic itching, scratching and friction, etc.

7. Inflammation and infectious diseases: chronic skin inflammation, etc.

8. Other factors. The causes of skin pigmentation are diverse, and it is difficult for patients to identify them themselves. They need to be diagnosed by an experienced physician. The nature of pigmentation due to different causes is different, and the treatment varies greatly. Finding the cause Although the diagnosis of the cause of skin pigmentation is more complicated, patients can still make a rough identification so that they can go to the corresponding department for treatment and take corresponding treatment measures.

9. Prevention and Treatment of Pigmentation Pigmentation is mainly about prevention, followed by correct treatment.

* Avoid contact with harmful chemicals and do a good job in occupational disease prevention and labor protection.

* Avoid local irritation to existing pigmentation, including scratching, rubbing and applying chemicals.

* Actively treat the primary disease. As the condition of the primary disease improves, the pigmentation will subside.

* There is currently no ideal drug for the treatment of pigmentation, so it is important to avoid drug abuse to prevent the condition from getting worse. Stop using any oral or topical medications suspected of causing pigmentation. For those with local inflammation, you can first use anti-inflammatory drugs such as 123 paste, zinc cream, etc. After the inflammation subsides, you can apply 3% to 5% hydroquinone cream which has a certain depigmenting effect, take a larger dose of vitamin C orally, and the Chinese medicine Liuwei Dihuang Pills also have a certain effect. In addition, you should increase the intake of fruits and vegetables in your diet, maintain a normal daily life, avoid sun exposure, etc.
