What it is

What it is
Broad protective areas of thickened skin from repeated pressure or rubbing.

What it looks like

Corns

A foot with a small yellow circular thickening on the little toe.

Corns A round area of thickened skin sits on the outer side of the little toe.

Calluses

The underside of a foot with a large rough yellow patch below the toes.

Calluses A broad yellowish patch lies beneath the ball of the foot.

In the skin

Repeated pressure or rubbing stimulates a focused buildup of outer skin. The dense central core can press into nearby tissue and cause discomfort.

Repeated pressure or rubbing stimulates protective thickening of the outer skin. The thickened area can become dry and less flexible, sometimes leading to cracks.

Corns. Can occur at any age with repeated mechanical stress.

Calluses. Can occur at any age with repeated mechanical stress.

Causes and triggers

Causes

Habits that help

Reduce pressure with well-fitting shoes or task-appropriate gloves
Address the rubbing that caused the thick skin.
Use a plain cushioning pad if it improves comfort
Padding should redistribute pressure without squeezing the area.
Moisturize dry thickened skin regularly
A plain cream or clinician-recommended foot product may soften the surface.
Ask for foot-care advice if the area stays painful
Diabetes, poor circulation or reduced sensation makes professional care particularly important.
Discuss podiatry assessment
A clinician can confirm the diagnosis, reduce thick skin safely and address footwear or deformity.

Avoid

Avoid: Cutting thick skin with blades or scissors
A small cut can become an ulcer or infection.
Avoid: Medicated corn acids on broken or high-risk skin
Seek advice before using them if you have diabetes, poor circulation or uncertain diagnosis.

Treatment differences

Evidence labels come from each condition’s own treatment list.

Treatment

● Corns

● Calluses

Treatment approach

Reduce pressure through suitable footwear and, when needed, podiatry care. Avoid cutting the corn yourself; ask before using medicated acids if you have diabetes, poor circulation or reduced sensation.

Address pressure and friction through suitable footwear or other protection. Professional reduction may help troublesome thick skin; avoid blades and seek advice before acids on high-risk feet.

Outlook

Long term

Corns can return if pressure or friction continues. Appropriate footwear and professional foot care can improve comfort; high-risk feet should be assessed before self-treatment.

Calluses can lessen when repeated pressure is reduced, but often return if the cause remains. Diabetes, reduced sensation or poor circulation makes professional foot care particularly important.
