Earwax & Ageing: How Cerumen Changes Over Time
Earwax becomes harder, drier, and more prone to impaction as you get older. Understanding why — and what to do about it — is particularly important for hearing aid wearers and anyone over 65.

What Is Cerumen and Why Does It Change with Age?
Cerumen — the clinical term for earwax — is a mixture of secretions from two types of gland in the outer ear canal: ceruminous glands (modified apocrine sweat glands) and sebaceous glands (oil-secreting glands). The ceruminous component gives wax its watery, slightly acidic character, which protects the canal from bacterial and fungal infection. The sebaceous component provides the lipid-rich fraction that lubricates the canal skin and gives wax its characteristic cohesion.
In younger adults, this mixture is self-regulating. The canal's epithelial cells migrate outward continuously, carrying wax with them. Jaw movement — chewing, talking, yawning — assists this migration by flexing the canal walls. The result is a slow, steady outward conveyor belt that keeps the canal clear without any intervention.
From the fifth decade onwards, multiple age-related changes disrupt this system simultaneously. Gland output falls, migration slows, canal hair becomes coarser, and the composition of the wax itself shifts toward a drier, harder consistency. None of these changes is dramatic in isolation, but together they produce a clinically significant increase in impaction risk. NICE NG207 acknowledges this directly, noting that age is one of the strongest independent predictors of cerumen impaction.
"Cerumen impaction is present in approximately one third of adults aged 65 and over, and in up to 57% of care home residents."

The practical consequence is straightforward: older adults need professional earwax removal more frequently than younger adults, and the wax they present with is harder and more adherent. Techniques that work well in younger patients — ear drops, bulb syringing at home — are often insufficient for the keratin-rich, compacted cerumen typical in patients over 70.
How Cerumen Composition Changes as You Age
Four distinct physiological processes drive the increase in earwax impaction among older adults. Each operates independently, but they compound one another in clinical practice.
Gland atrophy and reduced secretion volume
Both the ceruminous and sebaceous glands that line the outer ear canal undergo progressive atrophy from around the fifth decade onwards. Ceruminous glands — the modified apocrine sweat glands responsible for the watery, protein-rich component of earwax — reduce in number and secretory output. Sebaceous glands, which contribute the lipid-rich fraction, similarly diminish. The total volume of cerumen produced each month decreases, but the wax that is produced becomes proportionally drier and harder because the lipid-to-water ratio shifts unfavourably.
Increased keratin content and wax hardness
Cerumen in older adults contains a higher proportion of desquamated keratinocytes — shed skin cells from the canal epithelium. As skin cell turnover slows with age, these cells accumulate in the wax matrix rather than migrating outward efficiently. The result is a denser, more cohesive plug that adheres more firmly to the canal wall. This keratin-rich cerumen is significantly harder to soften with over-the-counter drops alone, and it responds better to professional microsuction than to irrigation, which struggles to penetrate the hardened core.
Slowed epithelial migration
The ear canal cleans itself through a process called epithelial migration — the skin of the canal grows outward from the eardrum at roughly the same rate as a fingernail, carrying wax with it. In younger adults, this migration rate is approximately 0.07 mm per day. Studies using radiolabelled markers show that migration slows measurably from the sixth decade, particularly in the posterior canal wall. Wax that would previously have reached the outer canal and fallen away instead stagnates, compacts, and eventually occludes the canal.
Coarser canal hair and mechanical obstruction
Androgenic hair follicles in the outer ear canal become more active in older men, producing longer, coarser tragi (ear canal hairs). These hairs physically trap cerumen before it can migrate outward, acting as a mechanical barrier. The effect is particularly pronounced in men over 70, where dense canal hair is a consistent clinical finding alongside impaction. Women experience a milder version of this change, but the combination of reduced migration and any degree of canal hair thickening still elevates impaction risk compared with younger adults.
Earwax Risk by Age Group
The following table summarises cerumen characteristics, impaction risk, hearing aid prevalence, and recommended removal intervals across the key age bands. These intervals align with NICE NG207 guidance and clinical practice at Earwax Removal Devon.
| Age | Wax Type | Impaction Risk | Hearing Aid Use | Recommended Interval |
|---|---|---|---|---|
| 50–64 | Transitional — lipid content beginning to fall, migration slowing | Moderate | ~15% of age group | Annually, or when symptomatic |
| 65–74 | Drier, harder — keratin content elevated, migration noticeably slower | High | ~40% of age group | Every 6 months for hearing aid wearers; annually otherwise |
| 75–84 | Hard, adherent — canal hair coarser, gland output significantly reduced | Very high | ~60% of age group | Every 3–6 months; more frequently if impaction recurs |
| 85+ | Severely dry, dense — often dark brown or black, firmly adherent | Very high (care home residents: ~57%) | ~70% of age group | Every 3 months; home visits available for those unable to travel |
Why Hearing Aids Accelerate Earwax Build-Up
Hearing aids do not cause earwax, but they significantly alter the conditions inside the canal in ways that accelerate impaction. Understanding these mechanisms explains why hearing aid wearers need more frequent professional removal than non-wearers of the same age.
Physical occlusion of the receiver port
Wax migrates into the receiver (speaker) port of in-the-ear and receiver-in-canal devices, blocking sound transmission. The patient hears a sudden, unexplained drop in amplification — often mistaken for battery failure or device malfunction.
Moisture trapping and canal inflammation
Hearing aids retain warmth and humidity in the canal, softening wax and increasing the likelihood of it spreading across the eardrum. Chronic moisture also promotes bacterial and fungal growth, leading to otitis externa that further impairs wax migration.
Feedback loop from wax-induced occlusion
When wax partially occludes the canal, the acoustic seal between the hearing aid and the eardrum changes. The device compensates by increasing gain, which can trigger whistling feedback — a common complaint that audiologists trace back to cerumen impaction rather than device failure.
Accelerated wax compaction from earmould pressure
Custom earmoulds and in-the-ear shells physically push wax deeper into the canal with each insertion. Over weeks of daily use, this compaction effect accumulates. Patients who wear hearing aids for 12–16 hours per day experience wax impaction at roughly twice the rate of non-wearers of the same age.
The right sequence: remove wax before adjusting the device
When a hearing aid wearer reports reduced amplification, feedback whistling, or discomfort, earwax impaction is the most likely cause. Returning the device to the audiologist before ruling out wax is a common and costly mistake — the audiologist will often find no fault with the device. A wax removal appointment should always come first. If symptoms persist after confirmed wax clearance, then audiological reassessment is appropriate.
Safe Earwax Removal for Older Adults
The choice of removal method matters more in older adults than in any other age group. The harder, more adherent cerumen typical in patients over 65 responds differently to different techniques, and several methods that are acceptable in younger patients carry higher risks in older ears.
Ear irrigation — the introduction of warm water under pressure — is contraindicated in patients with a history of ear surgery, perforated eardrum, mastoid cavity, or recurrent otitis externa. All of these conditions are more prevalent in older adults. Irrigation also struggles to penetrate the dense, keratin-rich plugs common in this age group, making it less effective as well as higher risk.
Microsuction is the method of choice for older adults, and it is the only technique recommended by NICE NG207 for patients with the contraindications listed above. It uses a fine suction probe under direct otoscopic vision — the practitioner can see exactly what they are doing at all times. No water enters the canal, there is no pressure on the eardrum, and the procedure is safe even in ears with previous surgery or perforation.
For patients who are unable to travel — whether due to mobility limitations, dementia, or care home residence — home visits bring the same professional standard of microsuction to the patient's own environment. Earwax Removal Devon offers home visits across North Devon and the surrounding area, with the same equipment and clinical protocols used in clinic.
Using Softening Drops Before Your Appointment
Olive oil drops, sodium bicarbonate drops, or proprietary cerumenolytic preparations (such as Earol or Otex) can soften hard wax before a professional appointment, making removal faster and more comfortable. The key is consistency: two to three drops in the affected ear, twice daily, for five to seven days before the appointment. Lying with the treated ear upward for five minutes after application allows the drops to penetrate the wax core.
Sodium bicarbonate drops are particularly effective on the dense, keratin-rich wax common in older adults — the alkaline solution disrupts the keratin matrix more efficiently than oil alone. They are available over the counter and are safe for long-term use. Avoid cotton buds entirely: they compact wax deeper into the canal and can cause micro-abrasions that increase infection risk.
Earwax impaction and cognitive symptoms in older adults
Severe bilateral earwax impaction can produce confusion, social withdrawal, and poor concentration in older adults — symptoms that are sometimes attributed to cognitive decline or early dementia. The British Geriatrics Society recommends routine ear examination as part of cognitive assessment in older patients. Wax removal in these cases can produce a rapid and striking improvement in apparent cognitive function. If an older relative seems increasingly confused or withdrawn, blocked ears are worth ruling out before pursuing a dementia referral.
Ear Symptoms in Older Adults: What to Do
Most ear symptoms in older adults are caused by wax impaction and resolve with professional removal. A small number of symptoms indicate a more serious underlying condition and require GP assessment first.

Questions About Earwax and Ageing
QWhy does earwax get harder as you get older?
The sebaceous glands in the ear canal produce less oil with age, reducing the lipid content of cerumen. At the same time, more desquamated skin cells (keratinocytes) accumulate in the wax matrix. The combined effect is a drier, denser plug that adheres more firmly to the canal wall and responds poorly to softening drops alone.
QIs earwax impaction a normal part of ageing?
It is common, but not inevitable. The physiological changes that increase impaction risk — gland atrophy, slower epithelial migration, coarser canal hair — are age-related, but regular professional removal prevents impaction from becoming a chronic problem. NICE NG207 recommends that adults with recurrent impaction receive regular maintenance removal.
QHow often should an older hearing aid wearer have their ears checked?
Every three to six months is the standard recommendation for hearing aid wearers over 65. Those who have experienced wax-related device malfunction, or who produce particularly hard wax, benefit from three-monthly appointments. A maintenance programme removes wax before it reaches the level of impaction.
QCan I use olive oil drops if I am older?
Olive oil drops can soften wax and are safe to use at any age, but they are less effective on the hard, keratin-rich cerumen typical in older adults. Drops work best as a preparation for professional removal rather than as a standalone treatment. Use them for five to seven days before a microsuction appointment for best results.
QIs microsuction safe for elderly patients?
Microsuction is the preferred method for older adults precisely because it does not introduce water into the canal, avoids the pressure changes associated with irrigation, and allows the practitioner to work under direct vision at all times. It is safe for patients with perforated eardrums, mastoid cavities, and those who have had ear surgery.
QCan earwax cause dementia-like symptoms in older adults?
Severe earwax impaction can produce cognitive symptoms — confusion, poor concentration, social withdrawal — that mimic early dementia, particularly in care home residents. These symptoms resolve after successful wax removal. The British Geriatrics Society recommends routine ear examination as part of cognitive assessment in older adults.
Regular maintenance for hearing aid wearers and older adults
Rather than waiting for impaction to cause symptoms, a scheduled maintenance programme removes wax before it becomes a problem. Patients over 65 and hearing aid wearers benefit most — appointments every three to six months keep the canal clear, protect device performance, and prevent the hearing loss and cognitive effects associated with chronic impaction.
