Karen,
I've never used the patches, but I used the cream Mederma on my scar when I had my thyroidectomy and my doctor recommended it for scars. I bought the product at Walmart. When people asked about my scar and I show it to them, they are amazed at what they see or should I say what they don't see.
Just an "FYI".
Be Blessed
E.
