How to clean behind your ears
Select an appropriate cleanser for your skin type.
Most people can simply use regular soap-whatever you wash your body with in the shower-to clean behind their ears. If you have sensitive skin, use a gentle foaming cleanser like a product you would use on your face.
Use a cleanser that you're familiar with-if it's comfortable on your body or face, it probably won't irritate the skin behind your ears. Use acne wash if you have blackheads.
