this is not a scab in my opinion. the theory that after each peeling cycle a new layer of skin is rebuilt is nonsense in my opinion. still, i believe that leaving them alone as much as possible is a good thing to do in many cases. i think one should avoid irritating the lips any further at any price. the root causes of this condition are wide-ranging and, as i believe, related to the digestive system in many cases. scabs on the lip however, heal faster and differently. even if we have a major wound on our lip with severe bleeding and all, it will heal within about 1 week.
