recreate the vermillion border

I notice I don't have any vermillion border between my lips and the mucous membrane inside the mouth.
Anyone have the same problem?
After two weeks the white collagen skin tissue builds up on the lips and trys to heal inside the mouth.
The tissue becomes big and unstable where it washes off.
There is a red sore wound that extends inside the lips and the cheeks.

If we can fix the vermillion border between the lips and the mucous membrane, then we can cure our lips. Anyone have any ideas to recreate the vermillion border? Tweet
