To help prevent this:
Wash facial hair daily with a gentle cleanser.
Use hair products that are oil-free or non-comedogenic.
Everyday things that touch your chin: Your chin touches many things every day, such as pillowcases, phones, and your hands. These can transfer dirt, oil, and bacteria to your skin.
Some people also rest their chin on their hands or spend a lot of time on their phones, which can worsen acne.
Simple habits that help:
Change your pillowcases twice a week.
Clean your phone daily.
Avoid touching your face too often.
When pimples might mean something more: Getting a few pimples is normal. But if acne keeps appearing or is severe, it could be a sign of an underlying health problem.
