summary

Some time ago, my best friend found that she was suffering from vitiligo, and there were several white spots on her face. Now she is embarrassed to go out for treatment. She wears sunglasses every day and let me accompany her to the hospital. Vitiligo is really ugly on her face. Let's tell you where the prone parts of vitiligo are!

Where is the predisposing site of vitiligo

First of all: many parts of people are easy to grow vitiligo, the site of each person may not be the same, excessive sun exposure parts, exposed parts of the skin vulnerable to sunlight, and excessive sun exposure, it will make the skin dark, some parts of the white spot or make the original white spot expansion. After the sun exposure, one is due to the hyperfunction of melanocytes, which promotes their consumption and early decline; the other is probably due to the excessive production or accumulation of melanin intermediates synthesized by cells themselves, which damages melanocytes, resulting in leukoplakia and aggravating the symptoms of vitiligo. In summer is the highest period of vitiligo, for the exposed skin must be prepared for protection.

Secondly, the parts vulnerable to friction and trauma, and the reason why trauma can induce vitiligo, some experts infer that tyrosine is the raw material of melanin, and also the raw material of some neurotransmitters. In the middle of its metabolism, there are two evolution routes: one is toward melanin evolution, the other is toward the synthesis of neurotransmitters; After trauma, the nerve structure and function change, which may increase the synthesis of neurotransmitters, consume too much tyrosine and reduce the synthesis of melanin, which may lead to vitiligo.

Finally: the exposed parts of human body often come into contact with biological or chemical substances, which are different in shape and composition. For example, in spring and summer, there are a lot of allergens in the air, which are very likely to cause skin allergy after contacting the exposed parts. If skin allergy cannot be handled carefully, infection may occur. For chemical substances, there are not only various corrosive substances that can directly damage the skin in life, but also some cosmetics can cause harm to the skin and cause all kinds of inflammation.

At ordinary times, we must take preventive measures. When we go out, we should remember to take umbrellas and be prepared for sun protection. We hope that patients' friends can pay attention to the daily protection of the above parts, avoid excessive sun exposure, avoid skin trauma and pollution, and prevent the occurrence of vitiligo!
