Causes of white blister on lip

  • Too much of friction can also cause blisters, especially on the lips. This also happens when one is out for a long time in harsh environmental conditions or a sudden change in environment. Also blisters are more easily formed on the moist areas so people with oily skin, are also more prone to having blisters on lips since they tend to collect moisture easily. Such a condition enhances in warm weather, sometimes leading to ulcers, infections etc.
  • Blisters on lips are also caused due to problems with the digestive system. In fact ulcers inside the mouth are also a manifestation of this condition. Too much acidity or indigestion causes pus-filled blisters.
  • Sometimes burning of the skin also causes blisters varying in intensity depending upon the degree of burn.
  • When the skin is exposed to certain chemicals present in products ranging from cosmetics to detergents, sometimes the reaction may be unfriendly also known as “contact dermatitis”. Chemicals mostly present in such products are nickel sulfate or Balsam. And their effects could be really painful.
  • White blisters on the lips can also become blood blisters when the little blood vessel near the skin area breaks and causes the blood to leak into the rupture between skin’s layers. If the skin is aggressively rubbed, pinched or squeezed then the condition can worsen.
  •  Even chickenpox, eczema, bullous pemphigoid, (especially among the ones over 60 years old), herpes etc causes blisters to develop.  In Dermatitis herpetiformis the blisters get itchy and can be more in number.
  • Blisters can also be called as canker sores and can also occur among individual because of stress or changes in the immune system. Deficiencies of vitamins such as B1, B2, B12, B6, iron, and zinc can also lead to sores. Irritation, injuries, or infected tissues are another reason too.
  • Hormonal changes and food allergies are among the most underestimated causes.
