Apply some Aquaphor on the scabs and leave there until it becomes white and soft. This might take a few hours. Then you can easily and gently remove the scabs. You then reapply the Aquaphor on the raw skin. You can apply it 3 or more times a day. Just make sure the lips don't ever dry out.
For the next few days the scab will try to grow back, so just repeat the method and soon the scab will stop forming.
As for lip licking, you can try this but I've found its harder to apply aqua on saliva because it won't stick.
