Earwax: Natural Solutions for Optimal Hygiene

Q: What is earwax (cerumen)?

Earwax is secreted by the sebaceous and apocrine sweat glands in the ear canal. It mixes with dead skin cells and hair to form cerumen. Its slightly acidic pH helps naturally limit microbial growth in the canal.

Q: How is earwax formed?

The formation of cerumen is a continuous, self-regulating process. A thin layer naturally moves outward due to jaw movements, carrying away dust and particles. This self-cleaning mechanism functions without intervention in most people.

Q: Dry earwax or wet earwax: what’s the difference?

The type of earwax is genetically determined. Wet earwax is yellow to brown, sticky, and more common among European and African populations. Dry earwax is gray to beige, crumbly, and more common in East Asia. These variations are normal and do not indicate a medical condition.

Q: How can you clean your ears safely?

Never insert any objects into the ear canal. Clean the outer ear with a damp cloth. If wax builds up, use a saline ear spray or a few drops of warm olive oil to soften the wax, as advised by a pharmacist. Cotton swabs are strictly prohibited.

Q: When should you seek medical attention for an earwax problem?

See a doctor or an ENT specialist if you experience pain, discharge, or a persistent feeling of a blocked ear; hearing loss that doesn’t improve with over-the-counter (OTC) products; or if you suspect an ear infection. A healthcare professional can safely perform irrigation or suction.

Earwax, a common term for cerumen, is a natural substance produced in the external auditory canal. Far from being waste, it plays an essential protective role. Its composition varies from person to person, which explains the differences in texture, color, and quantity that are observed.

What Is Earwax (Cerumen)?

Earwax is secreted by two types of glands in the ear canal: sebaceous glands and apocrine sweat glands. These secretions mix with dead skin cells and fine hairs to form earwax. The slightly acidic pH of this substance helps naturally limit microbial growth in the ear canal.

How is earwax formed?

Its formation is a continuous, self-regulating process. The ear canal constantly produces a thin layer of earwax that slowly moves outward due to jaw and skin movements, carrying away dust and particles. This natural self-cleaning mechanism works without external intervention in most people.

Dry earwax or wet earwax: what’s the difference?

There are two types of earwax, determined by genetics.

Wet earwax: yellow to brown, sticky, more common among European and African populations
Dry earwax: gray to beige, crumbly, more common among East Asian populations

These variations are normal and do not indicate a medical condition. However, a sudden change in color accompanied by pain or discharge warrants medical attention.

How can you clean your ears safely?

Ear hygiene is limited to the outer ear opening: never insert any objects into the ear canal.

Clean the outer ear with a damp cloth
Cotton swabs are prohibited: they push earwax deeper into the canal and irritate it
If wax builds up: use saline ear sprays or warm olive oil to soften it—as advised by a pharmacist
Avoid unformulated hydrogen peroxide solutions: they can be irritating if not properly diluted

Can earwax affect hearing?

In excess, earwax can form a plug that blocks the passage of sound. This can cause temporary hearing loss, a feeling of fullness, and sometimes tinnitus. Professional cleaning restoreshearing safely. Hearing aid users are at greater risk: the devices can block the natural drainage of earwax.

When should you seek medical attention for an earwax problem?

See a doctor or an ENT specialist if you experience:

Pain, discharge, or a persistent feeling of a blocked ear
Hearing loss that does not improve with over-the-counter remedies
Suspectedear infection (pain + fever)

A healthcare professional can safely perform an irrigation or suction procedure. Content reviewed by Arnaud, Ph.D. in Pharmacy.
