I am 3 weeks post op tomorrow and my doc recommended biodermis mastopexy silicone sheet for my tummy tuck scar wit vertical scar in middle. Rejuveness says it's fda approved & bbb accredited & biodermis is not. Which brand will give me better results 4 my scar? Rejuveness also says it helps with itching. Biodermis is clear silicone & Rejuveness appears more white & claims 2 be pure silicone. Price makes no diff I just want what's best. Responses are appreciated thanks.
