Introduction
A skin rash is a defensive reaction of the body, which manifests itself on the skin and is often caused by external stimuli. Alternatively, the term exanthema can be used. The body usually reacts with overheating, redness as a sign of increased blood circulation, small blisters or wheals or even with pain, itching or burning of the affected skin area. Depending on the spread, shape and localization of the rash, conclusions can then be drawn as to its cause. Pollen, as a biological material, can also cause such a reaction in the body of certain people and is then most likely to present itself on the surface in the form of an allergic rash.
Causes
The causes of a rash can vary widely, ranging from simple reactions to local irritation of the skin, to infections, to extensive infestation in the context of chronic diseases. Allergic reactions in the form of skin rashes are also conceivable, for example when the body reacts to otherwise harmless substances with an exuberant response from the immune system, thus declaring them foreign and allergenic to the organism. Both artificially, chemically produced and naturally occurring substances can be possible triggers. Pollen also falls into this category and can penetrate the skin via the hair follicles and locally trigger an allergic reaction with a skin rash. Very sensitive and dry skin is particularly at risk, where the skin barrier is already damaged.
Associated symptoms
Depending on the strength and extent of the immune response, accompanying symptoms of an allergic reaction can also include itching, watery eyes, a stuffy nose and shortness of breath. Pollen in particular can also trigger allergic asthma, which causes breathing difficulties for those affected, especially in spring.
Skin rash due to pollen on the face
An allergic skin rash caused by pollen can sometimes also manifest itself on the face, which is often perceived by those affected as cosmetically very stressful. But here, as for the rest of the body, it is important to protect the affected skin areas and strengthen their barrier function with moisturizing and less irritating creams or lotions. If necessary, cooling can also alleviate symptoms.
Under no circumstances should the skin be exposed to additional irritating substances, for example by trying to conceal the rash with cosmetics. In the acute phase, ointments containing cortisone can also help the inflammatory reaction to subside in the face. This is best discussed in individual cases with an experienced dermatologist.
