There has been no reported significant impact of filler injection on pregnancy, but the injection is not recommended during (potential) pregnancy. 

The length of time the results last depends on the type of filler. The most commonly used ones last from six months to one year.  

For a more satisfactory result, we recommend avoiding tough or chewy food to refrain from developing chin muscles.

Excessive dose of Botox injection may make your facial expression awkward since it paralyzes the facial muscles.  Note, however, that the effect does not last forever, and your facial muscles will recover over time.

That can happen when the muscles of both legs or levels of use are different.

Botox tolerance can vary from person to person. Large dose or too frequent injection may lead to tolerance (less effectiveness or shorter duration of effectiveness).

If you develop your calf muscles by heavy exercise after receiving Botox treatment, the effect may not be satisfactory. If you have to walk or exercise heavily, we recommend stretching your muscles.
