Anyone know why the guideline for not injecting 2’’ from the belly button. Heard this, but not the reason. Is it because the belly button is scar tissue?

I believe the two reasons are that there is more hard connective tissue around the belly button and that it is much less of a fatty layer beneath your skin with more blood flow.
