Wrinkle treatment by muscle relaxation injections.

We are not allowed to use the medical word that is the injected chemical  typically used for appearance improvement by relaxing muscles that generate frown and smile lines. One word would be a lot easier!
However one can say that every case demands a bespoke approach as we all express our faces a little differently. Additionally many patients are surprisingly asymmetrical. Subtle differences in injection technique are important to achieve an ideal result. It requires artistry and an appreciation of facial aesthetics. Anyone can inject but it is very common to see droopy brows, stiff expressionless faces and inappropriately weakened expressions when injections are performed by amateurs. Many injectors simply follow an injection pattern but not an individual patient’s particular requirements. The following Y-tube educational video is very good and does demonstrate the issues of muscle balance in the face.
