Combination therapy with BOTOX™ and fillers: the new rejuvnation paradigm

Until relatively recently, restoration of appearance by replacement of lost facial volume and muscular relaxation has been an illusory goal. With advances in the commercial availability of newer filling agents and a better understanding of the clinical esthetic effects of botulinum toxin A, remarkably sophisticated and refined results can now be achieved by using these noninvasive techniques. The combined use of BTX‐A and filling agents, such as collagen and hyaluronic acid, can restore facial appearance by the dual mechanisms of reflation and relaxation. In addition, their combined use appears to increase the longevity of tissue dwell time of the filling agent. Current practices now strive to correct wrinkles by restoring volume and also relaxing the pull of muscles that create negative facial expressions such as glabellar folds, mouth frown, crow's feet, horizontal forehead lines, and perioral and cervical rhytides. As with any of the new technological innovations currently available, understanding of the differing properties of the agents used and education in optimal technique is essential to clinical and esthetic success.
