The weather is hot, and little red dot appears on me. What should I do?

Problem analysis: Hello, according to your question, considering that the weather is hot and you sweat a lot, you have a little little red dot, which means it should be caused by hair follicle keratinization or related to allergies.

Suggestion: It is recommended to take vitamin C orally, pay attention to diet and avoid allergic foods, such as fish, shrimp, mushrooms and strawberries. When the weather is hot, clean your skin more, take a bath at noon and change clothes to avoid sweat stains staying on your skin for a long time, such as more and more rashes and itching. Go to the skin hospital in time and wish you good health!
