Irritation in skin can be caused by a number of factors such as medicinal side effects, infections or immune system disorders. When an allergen triggers an immune system response, it leads to a condition known as skin allergy. People having skin allergies may react to certain things that would not bother other people.
It might take you at least 10 days to be sensitive to something after coming in contact with it for the first time. You may even develop allergic reactions to something even after touching them for years.
