i'm 6 wks post op and my scar is healing nicely... flat, just still a bit red/purlple, but thin. i'm massaging 3 times per day with jojoba oil, fresh aloe in the morning. and jojoba oil and mederma at night. thinking about getting the silicone sheets... do these work?? help... don't mind paying (hell, we've already been through the worst right?) -- but wanted to make sure they work anyone.....????
