Corns & Calluses
Takes 2 minutes · No clinic visit · Delivered to your door
Calluses and corns are thickened, hardened patches of skin that form from repeated friction or pressure, most often on the feet or hands. They're extremely common and manageable, and can be assessed confidentially without an in-person exam in uncomplicated cases.
Could It Be a Callus or Corn?
- A thickened, rough patch of skin, often on the sole of the foot, toes, or hands
- A small, hard, well-defined bump (corn), sometimes with a tender centre, usually on or between toes
- Discomfort or pain when pressure is applied to the area, like standing or wearing shoes
- Skin that's noticeably tougher or more callused than the skin around it
- A pattern linked to a clear cause — ill-fitting shoes, repetitive activity, or a tool/instrument you use often
- No signs of infection, such as redness, warmth, or discharge
Treatment
- Topical salicylic acid (in various strengths and formats — liquid, pad, or plaster) to soften and gradually remove thickened skin
- Guidance on proper application to treat the callus or corn without irritating surrounding healthy skin
- Advice on footwear, padding, or technique changes to address the underlying friction or pressure causing it
- Guidance on safe, gradual removal rather than cutting or shaving at home
- Ontario pharmacists can assess and prescribe directly for uncomplicated calluses and corns

Frequently Asked Questions.
What causes calluses and corns?
Repeated friction or pressure on the skin, most commonly from ill-fitting or tight footwear, high-impact activities, or repetitive hand movements. The skin thickens as a protective response to that ongoing pressure.
How are calluses and corns treated?
A salicylic acid product applied directly to the affected area, which gradually softens and removes the thickened skin, combined with addressing the underlying cause (like footwear). Ontario’s minor ailments program allows pharmacists to assess and prescribe directly for uncomplicated cases.
How long until symptoms improve?
Most people notice the thickened skin softening and reducing within 1 to 2 weeks of consistent use, though larger or longer-standing corns and calluses can take several weeks of regular treatment to fully clear.
What's the difference between a callus and a corn?
A callus is a larger, flatter area of thickened skin, usually painless, that forms over a wider surface like the sole of the foot. A corn is smaller, more defined, and often has a hard centre that can be tender or painful when pressed, typically found on or between toes.
Is it safe to cut or shave calluses and corns at home?
Cutting or shaving thickened skin yourself carries a risk of injury or infection, especially for people with diabetes or poor circulation. Topical treatment is a safer approach, and your pharmacist can advise on proper technique.
When should I seek in-person care instead?
Seek in-person care if you have diabetes, poor circulation, or nerve damage in your feet, if the area shows signs of infection (redness, warmth, swelling, discharge), if there’s significant pain or bleeding, or if the growth doesn’t respond to treatment or you’re unsure it’s actually a callus or corn.
