Drink lots of water for your body..hydration ( do you take any meds that may dehydrate you?)
Are you a lip licker?? If you are you dry out your lips and the stains maybe irritating it?
Keeping a great lip stick/balm/color that moisturizer on that you try not to lick off.
And oh the stains should go on 1st.
You should stop the stains til you heal and then try all the above if they apply. HTH
