root cause

The causes of inflammation at the corner of the mouth are diverse and can also occur in combination.

Mechanical forces:

Even a jerky mouth movement can tear the corners of the mouth due to the strong pulling force.
Since the mouth area is populated with many pathogens, inflammation quickly occurs if a crack has formed at the corner of the mouth.
If the skin at the corner of the mouth is also very damp due to excessive salivation or is very dry, this puts a strain on the skin and it tears more quickly.
Herpes infection:

In combination with the so-called cold sore, an infection with herpes simplex viruses, inflammation occurs at the corner of the mouth.
The viruses linger in the body and are reactivated by certain circumstances, such as extreme stress or alcohol consumption.
They multiply especially in the transition area between red lips and skin, which is why the typical herpes blisters and crusts appear in the corner of the mouth.

An ointment that has antibiotic effects can only work if the cause of the inflammation was bacterial.
Furthermore, it may be that there is a bacterial infection, but the origin of the inflammation was completely different and the infection is a so-called suprain infection, in which the bacteria use the weakened skin as an entry point.

For this reason, a critical questioning of the origin of the inflammation should always be undertaken.
