Beyond aesthetics: Study assesses the functional effects of facial contouring with botulinum toxin

BANGKOK, Thailand: Given the growing demand for non-surgical facial contouring and ongoing debate about the functional effects of muscle-relaxing procedures such as botulinum toxin injection, a recent study in Bangkok has investigated whether botulinum toxin Type A (BTX-A) injected into the masseter muscles can reduce lower face volume without adversely affecting masticatory function. Its findings suggest that BTX-A masseter injections may provide effective cosmetic improvements without perceptible loss of oral function in healthy adults.
