Earwax is produced by two types of glands in the outer portion of your ear canal. It’s not a sign of poor hygiene or a problem to solve. Your body makes it deliberately, and in most cases, the ear canal cleans itself without any help from you.
How Your Ear Canal Makes Wax
Two types of glands sit in the skin lining your ear canal and work together to produce earwax. Ceruminous glands, which are modified sweat glands located deep in the skin, do most of the work. Sebaceous glands, smaller and positioned near hair follicles closer to the surface, contribute an oily component. The mixture of their secretions combines with dead skin cells to form cerumen, the technical name for earwax.
These glands only exist in the outer third of your ear canal, the section made of cartilage. The inner two-thirds, which is bony and leads to your eardrum, has no wax-producing glands at all. This matters because pushing anything into your ear canal can shove wax from the area where it belongs into the deeper, narrower section where it can get stuck.
What Earwax Is Made Of
Earwax is roughly 60 to 70 percent fats, including several types of fatty acids, lanolin, and paraffin-like oils. Another 20 to 30 percent is protein, mostly keratin, the same tough material that makes up your hair and nails. The rest is a mix of other organic compounds and dead skin cells. This greasy, slightly sticky composition is what gives earwax its ability to trap dust, debris, and small insects before they reach your eardrum.
Earwax also has a mildly acidic pH of about 6.1, which, combined with fatty acids and an enzyme called lysozyme, gives it genuine antimicrobial properties. It creates an environment that discourages bacteria and fungi from setting up infections in the warm, dark ear canal.
Wet Versus Dry Earwax
Not everyone’s earwax looks the same. There are two distinct types, wet and dry, and which one you produce is entirely genetic. A single gene called ABCC11 determines the difference. One version of this gene produces wet earwax, which is honey-brown, sticky, and moist. The other version produces dry earwax, which is flaky, gray or tan, and crumbly.
The dry variant is nearly universal in people of East Asian descent, with frequencies close to 100 percent in populations from northern China and Korea. It’s intermediate in Japan, southern Asia, and the Americas. In European populations, the dry type is uncommon, and in African populations, it’s almost completely absent. Neither type is better or worse. They simply reflect different ancestral populations and have no effect on ear health.
How the Ear Cleans Itself
Your ear canal has a built-in conveyor belt. The skin lining the canal constantly grows outward, from the eardrum toward the ear opening, in a process called epithelial migration. New skin cells generated near the eardrum push older cells outward. These migrating cells carry wax, trapped debris, and dead skin along with them. In a healthy ear canal, this migration happens at an average rate of about 0.11 millimeters per day, roughly the speed a fingernail grows. It’s slow, but it’s continuous.
Jaw movement from chewing and talking also helps. The joint of your jaw sits right next to the ear canal, and its motion gently kneads the canal walls, loosening wax and nudging it toward the exit. Once wax reaches the outer ear, it typically dries up, flakes off, or falls out on its own.
Why Wax Builds Up or Gets Impacted
When the self-cleaning system works normally, you never notice your earwax at all. Buildup happens when something interferes with that process. The most common causes fall into a few categories.
Putting things in your ears. Cotton swabs are the biggest culprit. Rather than removing wax, they compact it and push it deeper into the canal, past the point where the conveyor belt can move it out. Bobby pins, rolled tissue, and ear candles cause similar problems.
Hearing aids and earbuds. Anything that sits in the ear canal for extended periods can block the natural outward migration of wax. Hearing aids are particularly problematic because they both physically obstruct the canal and stimulate the glands to produce more wax. Hearing aid manufacturers report that 60 to 70 percent of devices sent back for repair have been damaged by wax buildup.
Ear canal shape. Some people are born with unusually narrow or sharply curved ear canals. Others develop narrowing from bony growths (common in swimmers) or scar tissue from past infections or surgery. A narrower canal gives wax less room to travel outward and makes impaction more likely.
Overproduction. Some people’s glands simply make more wax than average. This can be a normal variation, or it can be triggered by irritation, frequent ear cleaning (which paradoxically stimulates more production), or skin conditions like eczema affecting the ear canal.
Age. As you get older, earwax tends to become drier and harder, making it less likely to migrate out on its own. The ear canal skin also thins with age, which can slow the epithelial migration process.
Signs of an Earwax Blockage
Most earwax, even visible amounts, isn’t a problem unless it’s causing symptoms. When wax does fully block the ear canal, common signs include a feeling of fullness or pressure in the ear, muffled hearing or noticeable hearing loss, itching, ear pain, ringing in the ear (tinnitus), and occasionally a reflex cough. In rare cases, a large impaction can even cause a mild sense of imbalance. These symptoms often develop gradually, then suddenly worsen after water gets into the ear (such as after swimming or showering) because the wax absorbs moisture and swells.
Safe Ways to Deal With Excess Wax
The most important rule is to leave your ears alone if they aren’t causing symptoms. Visible wax at the opening of the ear canal is normal and can be wiped away with a damp cloth during a shower. Nothing smaller than your elbow, as the old saying goes, should go inside the canal itself.
If you’re experiencing symptoms of a blockage, over-the-counter ear drops designed to soften wax can help it work its way out naturally over several days. These typically contain mineral oil, baby oil, hydrogen peroxide, or saline. You apply a few drops, let them sit for several minutes, then allow the ear to drain. This often resolves mild impactions without any mechanical removal.
For stubborn blockages, a healthcare provider can remove the wax using irrigation (flushing with warm water), suction, or a small curved instrument called a curette. The procedure takes a few minutes and the hearing improvement is usually immediate. People who wear hearing aids, produce excessive wax, or have narrow canals often benefit from having this done on a regular schedule, sometimes every six to twelve months, to prevent recurrent blockages.
