Hi,
Botox works by chemically paralyzing muscle groups. If your doctor wants certain portions of the face to be positioned in a certain direction, he or she can use Botox to paralyze the muscle groups with cause the face to move in the opposite direction.
So, in the case of the brows, Botox can be used to perform a brow lift by targeting the depressor muscles of the brow. Along the inner portion of the brow, this is the corrugator, depressor supercilii and procerus muscles, which also are responsible for causing deep furrows. Along the outer portion of the brow, it's the tail of the orbicularis oculii muscle.
Make sure you see an experienced Botox injector with in-depth knowledge of facial and brow anatomy.
Best of luck.
