A rash is when skin gets irritated.
A rash can be red, bumpy, scaly, blisters, or itchy — or all of those things
at once! Another name for a rash is dermatitis.
Lots of things can cause rashes.
A chemical, like a soap, might irritate your skin. Or a rash can happen when
you touch something you're allergic to, like poison
ivy. Skin conditions like eczema
and dandruff also cause rashes.
