Can Use of Botox Cause Facial Expression to Change Once It Wears Off?

The muscles treated with botox have now returned to normal as it's been 8 months since your last treatment and it should function as it always had.  Possibly even before the Botox wore off, you had retrained your muscles and were using the outer forehead to help move the eyebrows when the Botox was effective.

It would be most helpful to study before and after photographs.  Ultimately if you are open to it, this is best assessed by superimposing the correct BOTOX treatment.  Over time it is most likely that facial expression will return to the state it wants to be in without the effect of BOTOX.  Consider a personal consultation with a BOTOX expert also look into my patented Microdroplet method.

Without knowing or seeing the activity of your facial expression muscles, botox will not change your facial expression overtime. However there are many different techniques of botox administration and there are areas where botox should be avoided in some patients. i.e. women with many transverse forehead lines, with low brows.
