Facial skin blisters can be brought about by various conditions. They can form at any age among healthy individuals, but most cases affect those with chronic health ailments, particularly those with weakened immune systems.
The blisters can be painful or painless, filled with fluid, blood or bacteria and tend to have a thin exterior layer that ruptures easily. It is vital to determine the root cause so that appropriate treatment can be started.
How to identify the facial skin blisters
The blisters or bullas are easy to identify which are localized swelling of the skin that contains watery serum or fluid brought about by irritation or chafing, burning or infection.
In most cases, the skin around the blister ranges from light to dark red. The facial skin blisters are generally caused by bacterial or viral infections and can be a cause for embarrassment.
What are the causes?
Herpes simplex
This is the most common viral infection that causes facial blisters. Generally, most carry the virus at one point, usually in early childhood. Upon initial infection, the virus causes several symptoms and becomes dormant in the nerves supplying sensation in the skin.
If the immunity level is poor, the virus might reactivate and move up the nerves and out on the skin where blisters form.
Herpes zoster
This is also a common cause for facial blisters which is the same virus responsible for chicken pox. Take note that the virus affects the nerves leading to the skin and can recur in adults as shingles.
Impetigo
The blisters of this skin condition are typically caused by the staphylococcus aureus bacteria. Children are usually affected especially if they touch their faces often or frequently pick on their noses.
