My face is quite chubby. I received jawline slimming injections two weeks ago, but there's been no improvement in my facial shape. Why aren't the slimming injections working?

The lack of effectiveness from slimming injections may be due to improper administration. For patients with wide mandibular bones, slimming injections will also be ineffective. Slimming injections are primarily used to improve masseter muscle hypertrophy and can achieve noticeable facial slimming results. The main ingredient in slimming injections is botulinum toxin, which works by blocking the nerve supply to the masseter muscle, thereby achieving a slimmer face. Generally, it takes about 2 to 4 weeks after injection for the effects to become apparent.
