\u201cHow is a callus (tylosis) different from a corn (clavus)?<\/span>\u201c
\u201cWhat should I do if I develop a callus?\u201d<\/p>\n\n\n\n

If you are struggling with skin conditions affecting your feet or hands, you are not alone.<\/p>\n\n\n\n

\ud83e\uddb6 A callus (tylosis) is a skin condition in which the skin on the feet or hands becomes hard and raised, and is also commonly known as a \u201ctaco\u201d (\u305f\u3053)<\/span> in Japanese.<\/p>\n\n\n\n

In this article, we explain the causes of calluses as well as available treatment options<\/span>.<\/p>\n\n\n\n

We also discuss the differences between calluses and corns<\/span> in the latter half of the article, so please read to the end.<\/p>\n\n\n\n

\ud83d\udd0d What Is a Callus?<\/h2>\n\n\n\n

A callus is a hard, thickened area of skin that forms mainly on the soles of the feet.<\/span><\/p>\n\n\n\n

Also commonly referred to as a \u201ctaco\u201d (\u305f\u3053)<\/span> in Japanese, calluses develop when the skin\u2019s outer layer (keratin) thickens in response to external pressure or friction<\/span>.<\/p>\n\n\n\n

\ud83d\udca1 Unlike corns, calluses involve only a raised thickening of the skin and are generally not painful<\/span>.<\/p>\n\n\n\n

\u2753 Why Do Calluses Form? Causes Explained<\/h2>\n\n\n\n

Calluses are caused by external pressure or friction<\/span>.<\/p>\n\n\n\n

When prolonged pressure is applied to a specific area, the skin\u2019s keratin layer thickens, resulting in a callus.<\/span><\/p>\n\n\n\n

They most commonly develop when ill-fitting shoes or sandals<\/span> place repeated stress on a particular part of the foot.<\/p>\n\n\n\n

\ud83d\udc60 In particular, high heels are a significant contributing factor to callus formation<\/span>. They force the feet into a cramped position and shift body weight onto the toes, making both calluses and corns more likely to develop.<\/p>\n\n\n\n

Additionally, wearing high heels over an extended period may alter the shape of the feet themselves, which can make calluses and corns more prone to forming<\/span>.<\/p>\n\n\n\n

\u26bd Calluses can also develop due to lifestyle factors such as sports or occupational activities.<\/p>\n\n\n\n

\ud83d\ude30 Are Calluses Painful? Symptoms Explained<\/h2>\n\n\n\n

In most cases, calluses are not painful<\/span>.<\/p>\n\n\n\n

Calluses form as the skin\u2019s natural protective response to external pressure, causing the keratin layer to thicken.<\/p>\n\n\n\n

Because the thickening occurs over a broad area, discomfort is generally minimal; in some cases, the affected area may actually become less sensitive to stimulation<\/span>.<\/p>\n\n\n\n

Note that calluses can develop in areas other than the feet as well<\/span>.<\/p>\n\n\n\n

While the feet are the most common site, people who frequently hold a pen may develop a \u270f\ufe0f\u201cpen callus\u201d (\u30da\u30f3\u3060\u3053)<\/span>, and those who sit in a formal kneeling position (seiza) often develop a \ud83e\uddd8\u201ckneeling callus\u201d (\u5ea7\u308a\u3060\u3053)<\/span>, making calluses a condition that can affect various parts of the body.<\/p>\n\n\n\n

\u26a0\ufe0f Although calluses are generally asymptomatic, extreme or repeated friction may cause the keratin to thicken further, sometimes resulting in a burning or uncomfortable sensation<\/span>.<\/p>\n\n\n\n
