How deep must Botox be injected for masseture reduction?

Thank you for your question! I inject into the belly of this muscle with a three point injection technique as this muscle is extremely strong. I would revisit your provider after two weeks from the date you received your injection if you don't receive your desired outcome. Best of luck to you!

Generally Botox should be injected into the muscle belly which is not superficial. My advice is to wait 2 weeks for the effects and top up if necessary
