What is ear wax?

The skin on the outer part of the ear canal has special glands that produce ear wax, also known as cerumen. The purpose of this natural wax is to protect the ear from damage and infections. Normally, a small amount of wax accumulates and then dries up and falls out of the ear canal, carrying with it unwanted dust or sand particles.

Ear wax is helpful to coat the skin of the ear canal where it acts as a temporary water repellent. The absence of ear wax may result in dry, itchy ears, and even infection. Ear wax is formed in the outer third of the ear canal.

What does ear wax look like?

Cerumen varies in form and appearance from person to person. It may be almost liquid, firm and solid, or dry and flaky. The color of ear wax varies depending upon its composition. Glandular secretions, sloughed skin cells, normal bacteria present on the surface of the canal, and water may all be present in ear wax.

The ear canals are considered to be self-cleaning. This means that ear wax and sloughed skin cells typically pass on their own from the inside of the ear canal to the outer opening. Old earwax moves from the deeper areas of the ear canal out to the opening. At the opening of the ear canal the ear wax usually dries up and falls out of the ear canal.
