Going in the jacuzzi? Will that make my Botox wear off faster?

Going into a jacuzzi will not make the Botox wear off faster.  Botox effects will last approximately 3 months and will fade gradually over time.  

Botox and other neuromodulators work by blocking the nerve response to the muscles.  The botox molecules are not really effected by anything other than each individual patient's metabolism of the proteins.   In general, nothing seems to help or hurt botox effects.  The only thing to avoid is massage or excessive pressure on the areas in the few hours after treatment as this could cause diffusion to unwanted areas.  Best of luck.
