Can Botox cause facial muscles to weaken and then result in my face sagging?

You’re correct in thinking that BOTOX may cause
your facial muscles to become weaker. Botox relaxes the facial muscles by
inhibiting neurotransmitter function in the muscle tissue, preventing them from
receiving electrical impulses and contracting normally. While this
neurotransmitter function can be regained after a typical Botox treatment, many
patients elect to have repeat procedures in the same area immediately after each
other. This can, in some cases, cause the facial muscles to atrophy and lose
some of their function. While this is certainly not a concern for most people,
if you’re worried about this outcome, make sure you give your body enough
chance to recover in between treatments.

Thank you for your question. In smaller muscles such as the muscles you have described, no. Botox will not cause sagging of the skin. Your best option would be to speak in person with an expert injector and discuss your problem areas. All the best,

It is the opposite, Botox is used to decrease the action of specific muscles that create fold or wrinkles. There are many facial muscles that will pull down some facial structures like the brows and jaw line, and then give an older or tired look on a patient. By using Botox wisely, you can avoid sagging on your brows, or along the jawline and neck, preserving a youthful appearance.
