Dry cracked corners of the mouth : Perleche

Dry cracked corners of the mouth

 

This is really common and can be really uncomfortable.  Patients will describe it as though they go to open their mouth to yawn and the corners of their mouth just crack or feel really sore!  “Mouth breathers” sleep with their mouth a little open at night. Their saliva builds up at the corners of their mouth and can start to break down this delicate skin.  If this goes on long enough, a yeast infection can develop called perleche.  The keep to preventing this is anticipating the problem.  If you are mouth breather, try applying Vaseline or aquaphor to the corners of your mouth before bedtime.  This can serve as a barrier to protect your skin from breaking down and getting irritated.
