Whereas in “conventional” B*TOX, the injections target muscles which give rise to particular wrinkles, the injections for The B*TOX Lift are targeted at specific muscles with a downward vector. These include the depressor anguli ori, orbicularis occuli and the platysmus muscle at the jaw line.
PLATYSMUS AND OTHERS MUSCLES
Besides the platysmus, other muscles like the constrictors of the eye and the Depressor Anguli Ori (DAO) are also weakened to allow an eyebrow lift and an up-tilt of the angle of the mouth respectively. The latter minimizes the marionette lines.
Dr David Loh first presented “The B*TOX Lift” in Singapore in 2006. It has since also been called the Nephrititi Lift among other names.
A slightly unbalanced smile is a possible but rare side-effect with another method called Intradermal B*TOX. The Zygomaticus major or the Levator labii superioris alaque nasi may be affected by B*TOX diffusing downward into them. They lie just beneath areas of skin where the injections are commonly admistered.
The side-effect can be consciously avoided in expert hands.
