Well what do we have from this thread:
A guy claiming topiramate worked for his scars.
A guy claiming lunesta seemed to improved his scars.
The common ingredient of these substances is : titanium dioxide.
There is a study(http://www.ncbi.nlm....pubmed/22962531)that shows oral titanium dioxide contributes to the formation of singlet oxygen that kills bacteria.
I think this didnt work for many people because similar things could only work in the absense of any other inflammation.
