Your ears produce earwax because two types of glands in the outer third of your ear canal are constantly at work: oil glands that produce a fatty substance called sebum, and sweat glands that release a thinner fluid. These secretions combine to form cerumen, the waxy substance you know as earwax. It cleans, lubricates, and protects the ear canal from bacteria and fungus. But when production seems excessive, the cause usually comes down to genetics, habits, skin conditions, or age-related changes in the wax itself.
What Earwax Actually Does
Earwax isn’t waste. It’s a self-cleaning mechanism. The ear canal is lined with tiny hairs that slowly move wax outward toward the opening of the ear, carrying trapped dust, dead skin cells, and debris with it. In a healthy ear, this conveyor belt works quietly in the background. You never notice it because the wax dries up and falls out on its own, often while you chew or move your jaw.
The problem isn’t usually that your ears are making too much wax. More often, something is interfering with the natural process of moving wax out, or the wax your body produces is thicker and stickier than average, making it harder for your ears to clear themselves.
Genetics Set Your Baseline
A single gene, ABCC11, determines whether your earwax is wet or dry. Wet earwax is honey-colored and sticky. Dry earwax is pale, flaky, and crumbly. People of East Asian descent are more likely to carry the variant for dry earwax, while people of European and African descent overwhelmingly produce the wet type.
If you inherited the wet-type variant, your glands naturally produce more of the oily, adhesive secretion that holds wax together. This doesn’t mean anything is wrong. It just means you’re more likely to notice buildup, especially if your ear canals are narrow or curved in a way that slows the outward migration of wax. Ear canal shape varies widely from person to person, and narrower or more angular canals trap wax more easily regardless of how much you produce.
Habits That Push Wax Deeper
Cotton swabs are the single most common reason people end up with excessive wax buildup. When you insert a swab into your ear canal, you push most of the wax deeper while only wiping a thin layer off the surface. Over time, this packs wax against the eardrum in a dense plug that your ear’s natural cleaning system can’t move.
Earbuds, hearing aids, and earplugs create a similar problem. Anything you regularly insert into the ear canal blocks the outward flow of wax and can stimulate the glands to produce more. If you wear in-ear headphones for hours every day, you’re both trapping existing wax and potentially triggering increased secretion from the friction and pressure.
Skin Conditions and Inflammation
If you have eczema or psoriasis, your ear canals can be affected just like the skin anywhere else on your body. Psoriasis in the ears causes scales of dead skin to build up inside the canal. These flakes mix with earwax and create blockages that wouldn’t form otherwise. The buildup can become dense enough to affect your hearing and cause pain.
Scratching or poking at itchy ears makes this worse. Pushing dead skin cells deeper into the canal compresses them against the eardrum. Even without a diagnosed skin condition, chronically irritated ear canals from allergies, frequent water exposure, or contact reactions to hair products can increase wax production as a protective response. Your glands ramp up output when the canal lining is inflamed, essentially trying to coat and protect damaged skin.
How Aging Changes Your Earwax
As you get older, the glands in your ear canal undergo changes that make earwax drier and harder. This sounds like it should mean less buildup, but the opposite happens. Drier wax doesn’t slide out of the ear canal as easily. It tends to accumulate and compact rather than migrating outward naturally.
Older adults also often have coarser, longer hair growth in the ear canal, which can physically trap wax. Combined with the drier consistency, this makes impaction significantly more common in people over 60. If you’ve noticed increasing problems with earwax as you’ve gotten older, this shift in wax composition is the most likely explanation.
Signs Your Wax Has Become Impacted
Producing a lot of earwax isn’t a problem until it blocks the canal. When that happens, the symptoms are hard to miss. The most common is a sudden, partial hearing loss in one ear, often described as feeling like your ear is stuffed with cotton. You might also notice a sensation of fullness or pressure, itching, ear pain, ringing (tinnitus), or even a persistent cough triggered by the wax pressing on a nerve in the ear canal. Rarely, a large impaction can cause mild dizziness.
These symptoms often appear suddenly, typically after water gets into the ear during a shower or swim. The water causes the wax plug to swell, completing the blockage. If you’ve had gradual hearing loss in one ear that seems to come and go, wax impaction is one of the most treatable explanations.
What You Can Do at Home
If your ears tend to overproduce wax, the simplest approach is to soften it regularly so it can migrate out on its own. A few drops of mineral oil, baby oil, or glycerin placed in the ear canal once or twice a week can keep wax soft enough for your ear’s natural cleaning system to handle. Lie on your side, put in the drops, wait five minutes, then let the ear drain onto a tissue.
Over-the-counter earwax drops (cerumenolytics) work the same way but use hydrogen peroxide or carbamide peroxide to break down the wax chemically. These are safe for occasional use but can irritate the ear canal if used too frequently. The key rule: never insert anything smaller than your elbow into your ear. That old saying exists because cotton swabs, bobby pins, and ear candles consistently make the problem worse, not better.
Professional Removal Options
When home softening doesn’t clear a blockage, a healthcare provider can remove the wax using one of two main methods. Irrigation involves flushing the ear canal with warm water using a syringe or electronic irrigator. It works well for most people, though complications occur in roughly 1 in 1,000 ears treated, including infection of the outer ear, eardrum perforation, or canal irritation. People with diabetes or weakened immune systems face higher infection risk from irrigation.
Microsuction uses a small vacuum to pull wax out under direct visualization, often with a microscope. A study of 159 patients found it successfully cleared the wax in 91% of cases. About half of patients reported minor side effects like dizziness or finding the procedure uncomfortably loud, but these were short-lived. Using softening drops for a few days before the appointment significantly reduces pain and dizziness during the procedure.
Neither method is clearly superior to the other based on current evidence. The choice often depends on what’s available at your provider’s office and whether you have any conditions that make irrigation risky, such as a history of eardrum perforation or ear surgery. For people who deal with frequent impaction, scheduling a professional cleaning every six to twelve months can prevent symptoms from returning.
