What is Skin allergy and rashes?
A rash is any change in the skin's colour, texture or feel — often red, itchy, bumpy or scaly. Allergic skin reactions happen when the skin reacts to something it touches, eats or is exposed to, while conditions like eczema and hives have their own patterns. In a humid climate, heat and sweat can also trigger rashes. Because the triggers vary so widely, identifying the cause is the key to lasting relief rather than relying on repeated creams.
