Callus
A callus is a natural protective response of the skin. It develops in weight‑bearing areas or anywhere
the skin experiences repeated pressure or friction. Over time, the body builds extra layers of hardened
skin to shield the underlying tissues.
Other Names for Callus
Hyperkeratosis – the medical term for thickened skin
Plantar callus – when it appears on the sole of the foot
Keratotic lesion – another clinical term for thickened skin
Pressure callus – emphasises the cause (pressure or friction)
Why Calluses Form
Normal pressure from walking or standing
Friction from footwear or being barefoot
Repetitive activities
Certain skin conditions (e.g., psoriasis) can also cause thickened skin
Temperature extremes (excess heat or cold) may contribute indirectly
Fungal infections often coexist because fungi feed on dead skin layers
When Calluses Need Care
Although calluses are usually harmless, they may require treatment if they:
Become too thick
Cause pain or discomfort
Develop cracks that can lead to infection
Lead to reduced light‑touch sensation or a feeling of numbness due to excess pressure on underlying nerves
Interfere with walking or daily activities
Management & Natural Remedies
Podiatrist reduction: Safe, professional trimming when callus buildup is excessive
Weekly pumice stone use after soaking to gently reduce thickness
Keratolytic creams (e.g., urea or salicylic acid) may be recommended to soften the skin
Vinegar foot soaks can help soften dead skin and may support management when fungal
involvement is suspected
