Corn treatment in Zurich

Corns and plantar warts (verrucae) can appear similar at first glance — but experienced dermatologists can clearly distinguish between them.

A corn (clavus) typically develops as a result of pressure and friction. Common triggers include ill-fitting shoes or foot deformities such as hammer toes or splayfoot. Visibly, it appears as a small, thickened area of skin on the foot. The pain experienced when walking or applying pressure is caused by a central cone-shaped core of hardened skin (the keratin plug) that can extend deep into the tissue.

To successfully treat a corn and prevent recurrence, it’s important not only to remove the corn itself but also — if possible — to address its underlying cause.

We gently remove the clavus using precise instruments or laser therapy. In the case of deeper corns, surgical removal under local anesthesia may be performed at our clinic in Zurich.

Debridement of Callused Skin

The affected area is softened (via laser or warmth), allowing the hardened surface to be carefully removed. Embedded keratin spurs are extracted, eliminating the source of pressure. From this point, effective prevention becomes essential.

Laser Ablation (Dermatology)

Using a specialized laser, we can precisely treat the corn’s outer callus and its deep keratin core. Surrounding skin remains intact. In most cases, the corn can be completely removed, and healing is typically rapid. Additional benefits include no open wounds and minimal discomfort. The combination of immediate relief and pressure reduction greatly reduces the chance of recurrence.

Surgical removal is reserved for very rare, deep-seated cases.

Preventing Corns

Corns tend to reappear if the underlying pressure isn’t addressed. Preventive measures include:

Ergonomic footwear: Proper fit, adequate width, soft materials, and low heels
Podiatric orthotics: Reduce pressure points
Foot care & maintenance: Regular podiatric check-ups; early treatment of emerging changes
Hydration & skin protection: Creams containing urea and skin-friendly lipids strengthen the skin barrier and reduce excessive keratin buildup

Treatment Overview

Your consultation and diagnosis take place at our clinic in Zurich. Depending on your individual case, treatment may begin right away. The method used will be chosen based on your specific findings. We will also provide detailed guidance on foot care and how to effectively relieve pressure long term.

Tip: Avoid tight shoes on the day of treatment. Opt for soft, breathable socks.

FAQ

When should I see a specialist for corns?

If the pressure area is already painful, red, or swollen
If you have diabetes or neurovascular conditions
If the corn returns despite regular foot care
If you’re unsure — to rule out other conditions

What is the difference between a corn and a wart?

A corn (clavus) is caused by mechanical pressure or friction, usually from tight shoes. A wart, on the other hand, is a viral skin lesion caused by HPV (human papillomavirus). Corns feature a central keratin core, while warts tend to be broader, may show pinpoint bleeding, and are contagious. Since it’s difficult for non-experts to distinguish between the two, we always recommend a professional assessment.

Why do corns keep coming back?

As long as mechanical pressure persists — for example, due to improper footwear or foot deformities — the callus will continue to form. Without addressing the cause, long-term resolution is unlikely. Because the core of a corn can penetrate deeply into the tissue, professional dermatological or podiatric treatment is recommended.

Are corns dangerous?

Corns are not dangerous in and of themselves, but they can be very painful. In chronic cases or when accompanied by conditions such as diabetes, there’s a risk of infection, delayed healing, or even ulceration.

What happens during laser treatment?

The laser targets the thickened skin and removes it layer by layer. The procedure is low in pain, sterile, and typically bloodless. Healing is usually complete within just a few days.

How long does healing take after removal?

Healing generally takes 3 to 7 days after manual or laser removal. In the case of deeply rooted corns, it may take longer. Consistent pressure relief is essential during recovery — we will discuss the best options with you during your appointment at Swiss Derma Clinic in Zurich.

Can I treat corns at home?

We strongly advise against self-treatment. Home remedies or over-the-counter salicylic acid plasters may soften the skin, but they also carry a risk of injury — especially for sensitive or diabetic skin. Professional treatment is safer and more effective. Also, distinguishing a corn from a wart is often not possible for non-medical individuals.

Which preventive measures are effective?

In addition to wearing comfortable, well-fitting shoes, orthopedic insoles, regular foot care, and avoiding repetitive stress on specific areas are key. Hydrating skincare also helps protect the skin barrier and prevents excessive callus buildup.
