Introduce savscar to doctor... He saying that scar formation is depends on patient skin and his technique... Some will heal well some will not.. Is very subjective... Just roughly go through the broschure and ask for sample.. Said can`t promise which patient he give to and whether patients come back to him after operation.. Give many sample but might don`t have result... Just remember dermatix popular brand.. Recently another rep give scar cream to him he can`t remember the brand and give to patient.. If sample given to doctor might no feedback and sound in the end
