A corn is a localised area of thickened skin that develops in response to repeated pressure or friction on a specific point — typically over a bony prominence. The skin's protective response to that repeated pressure is to produce more keratin at the point of contact, creating the hard, cone-shaped core characteristic of a corn.
Common causes:
Hard corns appear most commonly on the tops of smaller toes and the outer side of the little toe. Soft corns form between toes where moisture is trapped. Both become painful when the hard core presses on the nerve tissue beneath.
For patients with diabetes or poor peripheral circulation, even a small corn can progress to an ulcer or infection if left untreated — early professional evaluation is particularly important in these cases.
Pumice stones, corn plasters, and wider shoes reduce the pressure that drives corn formation — they do not remove the existing corn or address the bony prominence beneath it. For small, early-stage corns in patients without underlying structural issues, these measures can provide relief. For corns that have been present for months, that return repeatedly after self-treatment, or that cause significant pain with walking — professional removal is the appropriate next step.
Over-the-counter corn removal acids (salicylic acid plasters) are effective for superficial corns but carry a real risk of chemical burns to surrounding healthy skin, particularly in patients with reduced sensation or circulation. They should not be used by diabetic patients without medical guidance.
At Skinssence Laser & Skincare Clinic, corn removal is performed under sterile conditions with local anaesthesia. The procedure typically involves:
No hospital admission is required. Most patients walk out of the clinic after the procedure.
A clinical assessment also rules out plantar warts and calluses, which require different treatment approaches. Treating a plantar wart as a corn with salicylic acid plasters, or vice versa, delays resolution and can worsen the condition.
No — local anaesthesia is applied before the procedure. The area is fully numb during removal. There may be mild tenderness for 1–2 days after the anaesthetic wears off, which is manageable with standard pain relief.
If only the surface corn is removed without addressing the underlying pressure point or bony prominence, recurrence is common. At Skinssence, the assessment identifies the structural cause and addresses it as part of the procedure — significantly reducing recurrence risk compared to surface-only removal or home treatments.
Yes — with appropriate precautions and medical assessment beforehand. Diabetic patients should never attempt self-removal of corns because reduced sensation means injuries may go unnoticed, and impaired healing increases infection risk. Professional removal under controlled conditions is specifically important for diabetic patients.
Both cause painful raised lesions on the foot but have different structures and require different treatment. A corn has a smooth, hard surface with a central translucent core and is located over a pressure point. A plantar wart has an irregular surface with small black dots (thrombosed capillaries) visible and is caused by HPV infection. Misidentifying one for the other leads to ineffective treatment — a dermatologist examination provides accurate diagnosis.
Most patients resume normal activity within a few days. The treated site heals fully within 2–3 weeks depending on the size of the corn and whether any underlying structural work was done. Comfortable, wide-toed footwear during the healing period significantly speeds recovery.
