What is a cereumen?

Cerumen, commonly known as earwax, is a natural substance produced by glands in the ear canal. It serves to protect the ear by trapping dust, debris, and microorganisms, preventing them from reaching the eardrum. Cerumen also has antibacterial properties and helps to keep the ear canal moisturized. While it's normal for cerumen to accumulate, excessive buildup can lead to hearing issues or discomfort.
