What are Glabellar lines (frown lines)?
Glabellar lines: The wrinkles between the brows caused by the contraction of corrugator and/or procerus muscles. These lines are also known as brow furrows.
Results from a large, long-term study of patients receiving subsequent injections suggest that Botox® (botulinum toxin type A) may reduce brow furrow (glabellar lines) -- deep lines between the eyebrows - and lasts longer with each additional treatment.
