The tops, rims and backs of the ears are easy to miss when applying sunscreen – and they are often exposed for hours. To protect ears from UV, treat them as part of your face and scalp routine every time you head outdoors. This matters in Australia, where UV levels can be high even on cool, cloudy days, and where skin cancers commonly develop on frequently sun-exposed areas.

Ears can be particularly vulnerable because the skin is thin, curved and awkward to cover. Hair, sunglasses and a quick swipe of sunscreen may create a false sense of protection, but none reliably shields the whole ear. A practical daily routine and prompt attention to changing spots can reduce the risk of delayed diagnosis.

Why ears need specific sun protection

The outer ear, also called the pinna, receives direct sun from multiple angles. The upper rim, known as the helix, and the back of the ear are regularly exposed while walking, driving, gardening, fishing, playing sport or working outside. For people with short hair, thinning hair or a shaved head, the exposure can be greater still.

Skin cancer can occur anywhere on the ear. Basal cell carcinoma and squamous cell carcinoma are common non-melanoma skin cancers on sun-exposed skin, while melanoma can also develop on the ear. Some lesions may look like a small scaly patch, a sore that will not heal, a pearly bump or a dark spot that is changing. They are not always painful.

Men are often diagnosed with skin cancers on the ears more often than women, partly because shorter hairstyles can leave ears uncovered. But this is not a male-only issue. Anyone who spends time outdoors can be affected, including people with darker skin tones. Skin of colour has natural protection from some UV damage, but it does not eliminate skin cancer risk or the need to investigate a suspicious lesion.

How to protect ears from UV outdoors

The most reliable approach is to combine physical shade with correctly applied sunscreen. One method alone may not be enough during prolonged outdoor exposure.

Choose a hat that covers the ears

A broad-brimmed hat is one of the simplest ways to reduce UV exposure to the ears, face, neck and scalp. Look for a brim of at least 7.5 cm where practical, or choose a legionnaire-style cap with side and neck coverage. A cap with a narrow peak can shade the eyes but leaves the ears and neck exposed.

For work, gardening or long days near water, a broad-brimmed hat with a close weave offers better protection than a loosely woven straw style. UPF-rated clothing and hats can provide added reassurance, although a hat still needs to fit well enough to be worn consistently. The best option is the one you will actually keep on.

Apply sunscreen to the whole outer ear

Use a broad-spectrum, water-resistant SPF 50+ sunscreen on all exposed skin of the outer ear. Do not only cover the front. Apply it to the top edge, the folds, the earlobes and the skin behind the ears. If your hair is short or thinning, apply it along the hairline and scalp as well.

Apply sunscreen 20 minutes before going outside. Reapply every two hours, and sooner after swimming, sweating or towel drying. This can be easy to forget around the ears, especially when wearing sunglasses, headphones or a hat. Building it into your face application makes the habit more likely to stick.

Sunscreen should not be placed deep inside the ear canal. If you have irritated, broken or recently treated skin on or around the ear, ask your GP, dermatologist or pharmacist which products are suitable.

Plan around high-UV periods

Check the UV Index, not just the temperature. Sun protection is recommended whenever the UV Index is 3 or above. In much of Australia, that can be for long periods across the year. Cloud cover can reduce visible brightness without removing the need for protection.

When possible, plan strenuous outdoor work, exercise or errands outside the middle of the day, seek shade for breaks and keep a hat in the car, ute, work bag or by the door. These are small decisions, but repeated exposure adds up over time.

Do not rely on sunglasses or hair alone

Wraparound sunglasses may shade a small part of the upper ear, but they do not protect the entire ear or the skin behind it. Long hair can offer some coverage, yet it shifts in the wind and may not shield the ear during driving, swimming or sport.

People who wear hearing aids, earbuds or helmets may assume their ears are covered. These items can conceal a spot, but they are not designed as UV protection. They can also make it harder to notice an area that is persistently tender, crusted or bleeding. Remove them during your regular skin check so you can inspect the skin clearly.

Check your ears for changes

A skin check should include areas you cannot easily see. Use two mirrors, ask a partner or family member to help, or have a hairdresser, barber or health professional point out anything unusual. The back of the ears and the crease where the ear joins the head deserve particular attention.

Book a medical assessment if you notice a new or changing spot on the ear, particularly one that grows, changes colour or shape, bleeds, crusts, itches, hurts or fails to heal within a few weeks. A rough, persistent patch can be a sign of sun damage or a skin cancer, even when it seems minor.

The ABCDE guide can help identify melanoma concerns: asymmetry, border irregularity, colour variation, diameter that is growing, and evolution or change. However, not every melanoma follows these rules, and not every concerning lesion is dark. Trust a change that does not feel right.

When to arrange a skin check sooner

Do not wait for an annual reminder if a spot is changing. Arrange a prompt appointment with a GP or skin cancer clinician if you have a lesion on the ear that persists, bleeds without clear cause, forms a recurrent scab or looks different from other spots on your skin.

Early assessment matters because treatment is generally simpler when skin cancer is found early. Lesions on the ear can require careful management due to the thin skin and underlying cartilage, so delaying review can make treatment more complex. Knowledge can save your life, but acting on it is what creates the opportunity for early care.

People at higher risk should be especially vigilant. This includes those with a previous skin cancer, a strong family history of melanoma, fair skin that burns easily, many moles, a weakened immune system, or years of outdoor work and recreation. Your clinician can advise how often professional skin checks are appropriate for your individual risk.

Make ear protection automatic

Keep sunscreen near your toothbrush or face moisturiser, and put your hat where you will see it before leaving home. If you are responsible for children, include their ears when applying sunscreen – children often miss them because they are moving, wearing a cap or focused on getting outside.

Protecting your ears is not about achieving perfect sun avoidance. It is about recognising a commonly missed area and giving it the same attention as your nose, shoulders and scalp. The next time you apply sunscreen, pause at each ear, cover it properly, and arrange a skin check without delay if you find a spot that has changed.
