Producing a noticeable amount of earwax is usually a sign that your ears are working exactly as designed. Earwax is a natural lubricant and antimicrobial barrier, and some people simply produce more of it due to genetics, ear canal shape, or daily habits like wearing earbuds. The real question is whether you’re actually overproducing wax or whether something is preventing your ears from clearing it out naturally.
How Earwax Gets Made
Two types of glands line your ear canal and work together to produce earwax. Sebaceous glands, attached to tiny hair follicles, secrete an oily substance called sebum that keeps the skin inside your ears from drying out. Ceruminous glands, which are modified sweat glands, add antimicrobial proteins that protect against bacteria and fungi. The final product is a mixture of these secretions combined with dead skin cells, hair, and fatty compounds like cholesterol and squalene.
Your ear canal has a built-in conveyor belt. Skin cells on the canal wall slowly migrate outward at a rate of roughly 0.15 millimeters per day, carrying old wax toward the ear opening where it dries up and falls out. Jaw movements from chewing and talking help push things along. When this self-cleaning system works well, you never think about earwax at all.
Genetics Play a Major Role
A single gene variant largely determines both the type and amount of earwax you produce. A variation in the ABCC11 gene controls whether you have wet or dry earwax. People with two copies of the A version of this gene produce dry, flaky, grayish wax. Those with one or two copies of the G version produce wet, sticky, honey-to-dark-brown wax, which tends to be more abundant.
Dry earwax is most common in people of East Asian descent, particularly Chinese and Korean populations. Wet earwax predominates in most other populations worldwide. If your parents dealt with heavy earwax, you likely inherited the same tendency. This is the single biggest factor in how much wax your ears produce, and it’s not something you can change.
Earbuds and Hearing Aids Trap Wax
If you wear earbuds or hearing aids for hours each day, you’re likely noticing more wax buildup than you otherwise would. These devices physically block the ear canal’s self-cleaning process, preventing old wax from migrating outward. They can also irritate the skin and cartilage of the outer canal, which may prompt the glands to produce more secretions in response. People who wear headphones for many hours daily are significantly more likely to accumulate wax, even if their actual production rate is normal.
The fix isn’t complicated: take breaks from earbuds throughout the day, clean the tips regularly, and consider switching to over-ear headphones if buildup is a recurring problem.
Age Changes the Equation
Earwax problems become more common as you get older, but not because your ears necessarily produce more of it. The glands inside the ear canal gradually shift, producing drier wax that doesn’t move through the canal as easily. At the same time, the ear canal itself can change shape, and increased hair growth inside the canal can act as a net that traps outgoing wax. The self-cleaning mechanism slows down.
The numbers bear this out. Among Americans aged 12 and older, about 19% have some degree of earwax impaction. Among those over 70, that figure jumps to 32%. The likelihood of impaction increases roughly 20% with each decade of age. So if you’re noticing more wax as you get older, you’re in large company.
Narrow or Unusually Shaped Ear Canals
Some people have ear canals that are naturally narrower, more curved, or partially obstructed by bony growths. These anatomical quirks don’t necessarily increase how much wax your glands produce, but they make it much harder for wax to exit on its own. The result feels identical to overproduction: frequent blockages, muffled hearing, and a sense that your ears are always full. If you’ve had ear issues since childhood, canal shape is worth exploring with a clinician.
Common Habits That Make It Worse
Cotton swabs are the most common culprit. Pushing a swab into your ear canal doesn’t remove wax. It compacts existing wax deeper, past the point where the self-cleaning mechanism can reach it. Over time, this creates a dense plug that your ear has no way to clear. The glands keep producing new wax on top of the old impacted layer, making the problem progressively worse.
Other objects do the same thing. Earplugs worn nightly, in-ear monitors used by musicians, and custom earpieces for security or communication work all push wax inward or block its natural exit path. If you rely on any of these regularly, periodic cleaning becomes important.
When Buildup Becomes Impaction
Earwax impaction doesn’t require a complete blockage. It’s defined as any accumulation of wax that causes symptoms or prevents a clear view of the eardrum. Common signs include muffled hearing, a feeling of fullness or pressure, ringing in the ear, earache, dizziness, or itching. If you’re experiencing any of these, the issue isn’t necessarily that you produce too much wax. It’s that wax has accumulated faster than your ear can clear it.
Safe Ways to Manage Excess Wax
For most people, the ears need no cleaning at all. A washcloth over your finger, wiped around the outer ear after a shower, handles everything the self-cleaning system pushes out. If you do produce enough wax to cause symptoms, a few drops of mineral oil or hydrogen peroxide placed in the ear canal with a clean dropper can soften hardened wax and help it work its way out naturally. Use just enough to fill the ear, let it sit for a few minutes, then tilt your head to drain.
Ear irrigation kits, available at most pharmacies, use a gentle stream of warm water to flush softened wax. These work best after you’ve used softening drops for a day or two. Avoid irrigation if you have a perforated eardrum, ear tubes, or active ear pain.
What you should never put in your ear canal: cotton swabs, bobby pins, keys, pen caps, or ear candles. Ear candles have been shown to produce no suction and carry a real risk of burns and wax dripping into the canal. If home methods aren’t working, a clinician can remove impacted wax quickly using specialized tools or suction, and the relief is usually immediate.
