Is it safe to inject Botox into the muscles at the sides of the nose to reduce width (levator labii superioris alaeque nasi)?

I'm pretty sure this is different to bunny lines botox, as I've had that done and it made no difference to my issue I have muscle hypertrophy/excess tension in the muscles running down each side of my nose, along the nasal bone side walls, ending just above the nostril area. These are the muscles that can make a "snarl" expression. I think they're called "levator labii superioris alaeque nasi" The size of the muscles adds width to my mid-nose which I want to reduce. Is this safe/possible?
