Dear Daniel
I hate to tell you this but that is not the only remedy for scars,there are many.
Only the Well indicated remedy will work,its not one pill for everything-Homeopathy does not work like allopathic medicine.

Classical homeopaths understand the healing system ,going by the complex forms of Miasmatics scar formations fall under the sycotic miasm.

For a remedy to work it must be under the well indicated miasmic trait.
I have seen patients take Thios. for months with no results- they purchase this over the counter-or from a suggestion on line. This is not proper casetaking protocal.
The dose and potency is of EQual importance.Size #40 pellet is much too large(the Organon states homeopaths use size #10 poppyseed globules-wetdose-succussed)
If you have too many repetitions(of the same potency) you end up with a 'proving'.Also Not good.
My advice is to seek counsil for this by making an appt. with a trained classical homeopath so they can prescribe the proper remedy/potency/dose/dispensing method and do case monotoring/follow up on you.This way you will see results.
Homeopathy NEVER FAILS-only the homeopath (or self prescriber) fails.
