Calluses
Calluses
Calluses (/ˈkæləsɪz/; singular: callus) are areas of thick, hardened, dead skin, that form due to repeated friction, pressure, or other irritation. Since repeated contact is required, calluses are most often found on feet because of frequent walking and incorrectly fitting footwear. They can also occur on hands, or on any other part of the body where there is repeated friction.
Etymology
The term "callus" comes from the Latin callus, meaning "hard skin". It was first used in English in the 14th century.
Formation
Calluses form when the skin tries to protect itself against pressure and friction. The stratum corneum, the outermost layer of skin, thickens in response to repeated pressure or friction in a specific area. This thickening is a protective response by the body to prevent the skin from rupturing under stress.
Treatment
Treatment for calluses usually involves avoiding the repetitive actions that caused them to develop. Over-the-counter pads can help relieve the pressure on a callus. In severe cases, a doctor may recommend surgery to remove the callus. However, if the cause of the callus is not corrected, it will likely return.
