You might want to investigate something called "black salve". It is a blend of herbs which can remove or dissolve skin tags, moles, melanomas in about 10 days to 2 weeks time. It will not harm healthy tissue. I don't know if it will do anything to a scar though. Try it and see. Do a search on YouTube for "black salve". There is also bloodroot which is a herb with similar properties as black salve. Do a search for it also. Amazon has both. Black salve is sometimes called black ointment. Hope this helps.
