What causes a rash on the face?

There is a rash on the face, which is a typical manifestation of skin irritation. It is difficult to determine the specific cause of a single rash. It is necessary to make a comprehensive judgment based on other characteristics of the rash to draw a definite conclusion. Before that, we can first have a comprehensive understanding of the possible causes and figure out the problem as soon as possible. So, what causes rashes on the face? Let’s take a look below.

1. When you have a rash on your face, first suspect that it is a symptom caused by facial allergies. But don’t just think of “acne” when you see a rash on your face. In fact, skin allergies can also manifest as skin rashes. Skin allergies not only manifest as skin rashes, but also often cause skin itching, which can range from mild itching to severe itching. Sometimes severe itching can make people unable to sleep or eat. In addition, skin allergies may also cause many other symptoms such as blisters and scales.

Some people will experience more serious skin allergy problems when the seasons change: dry skin, itching, peeling, rashes, etc. Skin sensitivity is related to dry skin, as well as to the environment, climate, age, food and cosmetics. People who are prone to allergies should pay more attention to the balanced intake of dietary nutrition, eat more fruits and vegetables, and less fish, shrimp, beef, mutton, greasy, sweet and irritating food. It may also be a cosmetic allergy.

In order to prevent rashes caused by allergies, everyone should adjust their lifestyle habits, do not eat irritating and hot foods, do not scratch, do not stay up late, and keep bowel movements smooth every day. How to prevent facial allergies?

(1) Have a good attitude: First of all, you should understand that allergies only mean that the product is not suitable for this person and does not mean that the product is bad; any cosmetics may cause allergies; anyone may have allergies under certain circumstances.

(2) Find out the cause of allergies: stay away from allergens, and at the same time, improve your allergic constitution by removing free radicals and regulating immunity.

(3) It is best to avoid mixing skin care products, because the ingredients of skin care products from different brands are different. If you are not careful, chemical reactions will occur, which will make the allergic reaction more serious!

(4) When using cosmetics for the first time, be sure to test them before use. The specific method is: apply a small area on an inconspicuous part of the face to test it. After one night, if there is no abnormality, you can use it. During long-term use, the skin may sometimes feel irritated. When inflammation occurs, the use of this cosmetic should be discontinued.

If the facial allergy symptoms are mild, you can take some common anti-allergic drugs, which will generally subside after a few days. However, severe skin allergies still need active treatment. Failure to treat them will also cause many adverse consequences.

Itching and rashes caused by skin allergies can cause inconvenience to daily life and work.

If skin allergies are not treated in time, it will lead to uncontrollable itching. Not to mention children, even adults will not be able to help scratching, which will cause secondary damage to the skin, such as skin thickening, pigmentation, etc. If you scratch it, it may cause secondary bacterial skin infection.

If allergies are not treated in time, they may also lead to other complications, such as bronchial asthma. According to statistics, the risk of allergic rhinitis developing into asthma is three times that of normal people. For patients who suffer from both allergic rhinitis and bronchial asthma, the onset or aggravation of their asthma symptoms is often preceded by an onset of rhinitis.

2. Red rashes on the face may also be urticaria, commonly known as "wheals". It is a common skin disease caused by the dilation of small blood vessels in the skin and mucous membranes and the formation of local edema due to plasma exudation. Skin allergies can also manifest as "wheals", which is swelling of the skin above the skin surface, often accompanied by obvious itching. Some wheals are red, while others are white. They often come and go quickly, but often recur.
