Botox - Are the Lines Supposed to Completely Disappear? AND my First Shot Lasted One Month

The dynamic lines which are created by years of activity in the brow area are not always eliminated by Botox.  Some patients have very deep lines which will be softened, while other patients have lines/creases which are effectively erased after treatment with Botox. Immobility of the forehead is possible with larger doses (number of units received) if desired. The average duration of Botox is about 3 months.  Generally, a short duration of Botox (1 month) is related to an inadequate dose  or handling issues with the Botox.

Skin creases may take a while to disappear as they were created over many years. If the crease is a static line, one that is there from sun damage not muscle movement, then it won't improve with botox injections. If the line is related to years of muscle contraction in that area, and if those muscles can safely be treated with botox injections without interfering with vital muscle function (such as muscles that allow us to smile and speak correctly) then that line may improve over time. Botox usually lasts three to four months as does Dysport.  You may need more units to get a longer duration of effect, but again, if it's not the glabellar muscles which make your skin crease on the nasal bridge, but the nasal muscles, then botox injections would have to be directed to a different area. It is possible though that working lower on the bridge of the nose and sides of the upper nose to accomplish this could interfere with the upper lip muscles.
