How Is Ear Wax Formed?

Ear wax forms in the outer third of the ear canal.

Ear wax, technically known as cerumen, is a waxy substance found in the outer part of the ear canal. It traps dust, bacteria and other particles to prevent them from getting into the inner ear where they could cause irritation, infection or other damage.

Cerumen Glands

Ear wax is a substance produced by the cerumen glands in the ear canal. After the glands secrete cerumen, it slowly works its way towards the outer part of the ear canal.

Consistency

When first formed, ear wax is oily and soft. In time it becomes firmer and flaky. As it dries, it usually falls out of the ear.

Prevention

You can't prevent ear wax from forming, nor should you want to, because it serves an important purpose. Excessive ear wax may cause your ears to itch, though, or may even make hearing difficult. The American Academy of Otolaryngology recommends against trying to clean extra wax from your ears with cotton swabs and suggests irrigating your ears with a solution of saline and warm water instead (your physician can do it for you if you don't know how or feel uncomfortable with the procedure).
