Occasionally the treatment wears off very quickly or does not work at all.
Botulinum Toxin is best at treating dynamic facial lines; those caused by facial muscle activity, lines present at rest may or may not improve and can be unpredictable. I have considered alternatives to treatment, including doing nothing, topical creams, chemical peels, laser treatments, surgical denerva-tion, forehead/brow lift, facelift, or hyaluronic acid treatments and elected that at this time Botulinum toxin is the best option for me.
