What Causes Hard Skin Under Toe Nails?

Hard skin under toe nails, medically known as subungual hyperkeratosis, is a common condition that can be caused by several factors:

  • Friction and pressure: Repetitive rubbing or pressure on the toes can cause the skin to thicken and become hard. This is often seen in people who wear tight-fitting shoes or participate in activities like running or hiking.
  • Genetics: Some people are more prone to developing hard skin due to their genetic makeup.
  • Nail fungus: A fungal infection of the nail can cause the skin underneath to become thick and discolored.
  • Trauma: Injuries to the toe, such as stubbing or dropping something heavy on it, can lead to the formation of hard skin.
  • Other medical conditions: Certain medical conditions, such as psoriasis or eczema, can also cause thickening of the skin under the toe nails.

Treatment options:

  • Footwear adjustments: Wearing shoes that fit properly and provide ample toe space can help reduce friction and pressure.
  • Soaking and exfoliation: Soaking the affected area in warm water and using a pumice stone or foot file to remove the hard skin can help soften and smooth it.
  • Over-the-counter products: There are products available at pharmacies that contain salicylic acid or urea, which can help break down and dissolve hard skin.
  • Medical treatment: In severe cases, a podiatrist may recommend surgery to remove the thickened skin.
  • Is hard skin under toe nails contagious? No, it is not contagious.
  • Can hard skin under toe nails lead to other health problems? In some cases, it can cause pain, inflammation, or infection.
  • How can I prevent hard skin under toe nails? Wear comfortable shoes, trim your toenails regularly, and moisturize your feet.
  • When should I see a doctor about hard skin under toe nails? If home treatment doesn't improve the condition, it's best to seek medical advice.
  • What is the difference between hard skin and a corn? Hard skin is a general term for thickened skin, while a corn is a specific type of hard skin that forms on the top or side of a toe.
