How long does it take for the effects of jaw botox to wear off if the results are unsatisfactory and I wish to regain my old facial structure?

Hi,

While the effect of jaw Botox in reducing the contraction power of the jaw muscles will wear off in 4-6 months, the effect on the facial appearance may take several months more to normalize as the reduced muscle bulk will take more time to get back to its normal size.

Hope this helps!
