Blister on Lip
-
A blister is an area on the skin where the epidermis separates from the dermis. The space created between the two layers is then filled up with a clear liquid fluid called serum.
-
Blisters will appear as an area of raised skin on (in this case) a person’s lips which will then burst and form a hard crust.
In a week or so, the scabs will peel off and heal by itself. -
Prior to the onset of a lip blister, a person will feel an itching and burning sensation on the soon-to-be infected area of the skin. After which, blisters will appear.
-
Normally, blisters will disappear in a week but if these do not go away within ten days or more, it is advisable to seek a doctor immediately.
