It can occur with products such as shaving lotion, sunscreen and a few perfumes. Eczema, also called atopic dermatitis, affects  between 10 and 20 % of children and 1 to 3 % of adults. A widespread symptom of eczema is dry, pink, irritated and itchy skin.
Host factors embrace heredity, sex, race, and age, with heredity being by far probably the most vital. However, there have been latest increases within the incidence of allergic disorders that can not be explained by genetic elements alone. Four main environmental candidates are alterations in publicity to infectious illnesses throughout early childhood, environmental air pollution, allergen levels, and dietary modifications. Certain diets are formulated to reduce back the itch caused by atopic dermatitis.
Symptoms often begin inside minutes of exposure to the set off, however may be delayed by several hours. Many of the symptoms and signs of anaphylaxis might mimic other clinical situations, thus resulting in a delay in prognosis . For this purpose, the primary attack is particularly dangerous. Having experienced the signs once, a surviving patient is more doubtless to recognise their prevalence in the future thus aiding earlier analysis and therapy. Over 90% of patients with anaphylaxis will develop cutaneous symptoms similar to urticaria , itching, and angio-oedema that can help to  distinguish the condition from different diagnoses.
Depending on the severity, anaphylaxis can include skin reactions, bronchoconstriction, swelling, low blood strain, coma, and death. This sort of response could  be triggered abruptly, or the onset could be delayed. The nature of anaphylaxis is such that the response can appear to be subsiding but could recur throughout a time period. Red, bumpy, itchy skin can be irritating, painful and embarrassing.
More severe signs like a drop in blood stress and trouble respiratory may be life-threatening.
