What can I do to minimize the appearance of keloid scar after tummy tuck? 33 y/o (photo)

I had a tummy tuck surgery in September of 2022. Since then I have tried silicon patches 24/7, some different types of oils, and massaging the scar. It only seems to get worse and worse. Bigger and redder. I’m wondering what else I can do, or if I’ll just have to pay to have a revision. I’m worried that my skin will just keloid again if I try that. I do not normally scar this way.
