What happens if skin allergies don't itch?

It is actually not common for skin allergies to not itch, because under normal circumstances, skin allergies often lead to itching. If a person has skin allergies and it does not itch, then in this case a large area of ​​erythema will often appear on the skin, and the skin will feel particularly dry in a short period of time. The most fundamental reason for this phenomenon is allergic reaction, which is because when external allergens come into contact with the skin, the skin produces corresponding antibodies. These antibodies will trigger their own antigenic reaction, which will cause skin erythema, and sometimes papules or wheals.

There are many reasons why skin allergies do not itch, and the specific reasons are not very clear at present. Generally speaking, it may be the result of the combined effect of various comprehensive reasons. These comprehensive reasons may be racial, physical and chemical stimulation, certain environmental factors, or even psychological factors that may cause skin allergies without itching. Once you find that your skin is allergic but not itchy, you should find out the cause of the allergy in time and avoid contact with factors that can induce allergies in the future.

In fact, skin allergies without itching may also be caused by certain age factors. In daily life, we often find that young people are more prone to skin allergies than the elderly. Red patches appear on the allergic skin, but they are neither painful nor itchy. The painless and non-itchy patches caused by skin allergies can often disappear on their own in a short time. The reason why young people are more prone to skin allergies is that younger people tend to have stronger nerve sensory functions, while older people have relatively weaker skin nerve sensory functions.
