Cerumen traps dust bacteria and dead skin to preserve ear canal health

Earwax or cerumen is produced by specialised glands in the outer ear canal. Combining sticky lipids, proteins, and dead epithelial cells, cerumen lubricates the ear canal, repels water, and traps dust and microorganisms to prevent ear infections.
