Botulinum toxin A treatment of perioral rhytides.
BACKGROUND
Botulinum toxin A is well documented as a useful therapy for smoothing dynamic facial rhytides of the upper face. Most controlled studies have focused on the treatment of glabellar frown lines, horizontal forehead lines, and crow's feet. Reports of botulinum toxin A use in the lower face are few and anecdotal.


OBJECTIVE
We present our experience using botulinum toxin A in the lip as a treatment of vertical perioral rhytides, which resulted in the added cosmetic benefits of lip eversion and enhanced lip fullness.


METHODS
Eighteen patients were injected with botulinum toxin A into the vertical lip rhytides. The effect of treatment was evaluated at 2 to 3 weeks after procedure.


RESULTS
Smoothening of hyperfunctional lines and upper lip fullness/eversion is observed in patients treated with perioral botulinum toxin A injections; 72% of patients continued treatment.


CONCLUSIONS
In select patients, perioral botulinum toxin A results in amelioration of perioral rhytides and enhancement of lip fullness and lip eversion.
