Botox Plus Filler Offers Longer-Lasting Results in Glabella

A split-face study of 20 patients revealed that combination treatment with botulinum toxins and hyaluronic dermal fillers for forehead and glabella rhytides produced longer-lasting results than treatment with toxins alone. Meghan Dubina, MD, et al, of the Department of Dermatology, Northwestern University, Chicago, injected botulinum toxin alone on one side of the forehead/glabella and hyaluronic acid filler followed by botulinum toxin on the other side.
