A blister is an area on the skin where the uppermost skin layer (epidermis) separates from the middle layer (dermis). A clear fluid, called serum, develops and fills this gap. It is followed by the regrowth of epidermis from beneath. Formation of blister is actually one of the results of some sort of defensive activity carried on by your body against a harmful foreign body. Thus, there can be several factors that may cause blister on lip.
Causes of Blister on Lips
If you suffer from recurrent episodes of blister on lip, you may witness its onset while going through a stage of weak immunity. A virus, called herpes zoster, resides in the nerve nodes of such individuals. It stays till it finds the conditions in the body favorable for its growth and reproduction. The virus travels through the nerve to the skin (here lips) and causes the formation of blisters. Such a condition develops when your immune system gets weakened. It may occur when you go through a stage of physical or emotional stress. The other reasons behind the formation of blisters include injury to the mouth, excessive exposure to sunlight, extreme cold or hot temperatures and hormonal imbalance occurring during menstruation and pregnancy. Blister on lips may also occur by skin trauma caused by shaving, microbial infection, respiratory illnesses and food allergies.
