Scar healing lotion \ cream \ gel -- BioCorneum worth the cost?

Hi! So I am a week out from a LBL and was provided one bottle of the BioCorneum, but told I would most likely need more at $100 a pop! I saw other options for buying on Amazon, but I also know they sell a lot of fake products. My question is, are there no alternatives to BioCorneum that are equally as good and at a lower cost, or should I suck it up and pay $100 a bottle? Thanks!

I've used it for some of my scars, and haven't for others, and I don't see a significant difference.
