Actinic Keratosis

  • also known as solar keratosis, is a precancerous lesion of the epidermis (outer layer of the skin) that is caused by long-term exposure to sunlight.
  • Chronic sunlight exposure alters the keratinocytes (cells that make up the majority of the epidermis) and causes areas of your skin to become scaly, rough, discoloured and sometimes tender to touch.
  • AKs are most commonly found on sun-exposed areas such as the face, lips, ears, neck, scalp, forearms and backs of hands.
  • People who have fair skin and light-coloured hair and eyes are at the greatest risk of developing AKs.
