Topical steroid

Okay kiddo, a topical steroid is a type of medicine that you put on your skin when you have a boo-boo or an itchy rash. It helps to make the boo-boo or rash feel better by reducing swelling and redness.

The medicine contains a special ingredient called a steroid, which is different than the kind of steroids that athletes might take to get stronger. This kind of steroid works by slowing down the cells in your skin that are causing the swelling and redness.

It's important to only use topical steroids when a doctor or grown-up tells you to, and to follow the instructions carefully. They can be really helpful for some people, but too much or using them the wrong way can be harmful to your skin and body.
