What causes sudden rash on the skin?

If there are rashes on the skin, it is usually caused by allergies. There are many reasons for this allergy, such as some allergic dust, pollen, harmful gases, etc., which can easily induce such symptoms. In addition, some bad cosmetics are also important causes of rashes. If you have an allergic constitution in your daily life, try to eat less irritating food in your diet.

(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 a new cosmetic for the first time , be sure to test it before using it. 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.

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.
