What is the cause of the red papules

As the weather gradually gets warmer, there are more and more allergic substances in the air, which cause great harm to people's bodies. For example, many people have developed red papules on their skin in outdoor environments. These papules will make people feel itchy and very uncomfortable. Let's take a look at the explanation of what is going on with red papules.

Red papules are also called atopic dermatitis or "allergic eczema". They are mainly caused by the stimulation of allergens on the allergic constitution, which in turn causes skin inflammation. This is a chronic allergic disease caused by genetic constitution. Among allergic diseases, about 10% will become atopic dermatitis.

1. Specific predisposing areas :

The most distinctive symptom of atopic dermatitis is that it has specific predilection sites at different ages, and the condition is sometimes better and sometimes worse, often recurring.

Before the age of five, the most common areas are around the eyes, mouth, nose, and cheeks, followed by the outside of the arms and chest. In school-age children, the most common areas are the elbows, knees, and hands. Since the main symptom of atopic dermatitis is "itching", many young patients will scratch themselves, but the more they scratch, the more itchy they become. As a result of this vicious cycle, they often leave scratch marks or scars on the affected area, which makes the skin color darker and causes more dandruff to fall off!

2. Age of onset:

Most patients develop the disease at an age of less than six months, after which the symptoms will repeatedly worsen or improve; most patients will experience a significant alleviation of symptoms after the age of six; and 75% of patients will recover naturally by puberty. However, if it is severe systemic atopic dermatitis and half of the family members have this symptom, it may persist into adulthood.

3. Treatment:

Since atopic dermatitis is a symptom caused by an allergic constitution, the only way to recover is to work hard to improve your physical condition. When the rash is itchy, you can use appropriate medication to relieve it.

Doctors usually prescribe steroid ointments and oral antihistamines to relieve itching. However, if the rash starts to secrete or even emits an odor, it means there is a bacterial infection and you must see a doctor immediately. The doctor will prescribe oral antibiotics and ointments depending on the situation to prevent the condition from worsening.
