What is an allergic rash?
An allergic rash is a type of skin reaction that occurs when the body comes into contact with an allergen or substance against which the body defends itself with an excessive immune response. Allergens that cause allergic rash include pollen, dust mites, food, medicines, animal hair and sometimes the ingredients of cosmetic products. Allergic rash appears all over the body – on the hands, feet and face.

Types of allergic rash: What does a skin allergy look like?
The different forms of allergic rash are often difficult to distinguish from each other because they show very similar, if not identical, symptoms. The main difference can be found in the allergens that triggered the allergic reaction. Allergic rash can take the form of:
- Hives – Urticaria is a form of allergic rash whose symptoms include itching, redness and swelling of the skin. You may also encounter raised red blisters. Urticaria is not necessarily triggered by allergens. Body temperature, contact with water or even pressure on the skin can play a role in its development.
- Contact dermatitis – This allergic rash appears at the exact spot where contact with the allergen occurred. The cause is therefore usually chemicals (e.g. household cleaning products), cosmetics, tattoo inks or medicines applied to the skin. Symptoms can include redness, itching, dryness and blistering, but these symptoms only appear after a certain period of time. Some people may also be uncomfortable with contact with certain plants such as nettles.
- Eczema – Eczema is a chronic form of allergic rash that usually occurs in the folds (elbow and knee sockets), on the hands, including the fingers, and on the feet, especially the toes. Eczematous skin is itchy, dry, red and in some cases swollen.
- Photodermatitis – This reaction occurs after exposure to sunlight in combination with certain substances that may be photoreactive. After exposure to the sun, the allergic rash is red, itchy and blisters are no exception.
