Is There Any Way to Speed Up Botox Activation Such As Drinking Lots of Water, Exercise, Heat?

The short answer is no.  Results from Botox are typically seen starting at 4 days.  It usually takes 10 to 14 days to see the result.  

There is no way to speed up Botox activation but if you need a faster onset of action, the next treatment you can ask for Dysport, which is a botulinum toxin serotype A just as Botox Cosmetic is, but may have an affect a day earlier than Botox.

A number of things have been suggested to either speed up the onset of Botox or minimize side-effects, such as exercising or not exercising the muscles where it was injected, not lying down, not traveling by plane, etc. A consensus of experts agree that probably none of these is important. Dysport may take effect a little bit faster, and the newer (but not yet available in the U.S.) formulations Xeomin and Puretox may have a different time to onset.

Botox takes about 24 to 48 hours to see any effect.  In my opinion, treatment is maximal at about 3 weeks.  If you just had service and were hoping to be transformed by Saturday night for a Bar event, I am afraid you are going to be disappointed.  I would recommend in the future that you plan ahead.  Generally I do not recommend getting service immediately before an event, especially an important event like meeting with judges, client events, weddings, you get the idea.  Schedule treatment so that if you bruise or require a treatment adjustment, you have time for this.  For BOTOX, 3-4 weeks is about right.  For filler, 4 weeks is generally very good.  However for a wedding (particularly your own wedding) have filler service at least 8 weeks a head of time.  Collagen for the lips was the idea pre-event lip edge treatment.  It stimulated almost no bruising or swelling and could be placed the day before a red carpet event.  That product would only last a couple of weeks anyway.  Plan ahead!

Botox and Dysport are neurotoxins injected in minute amounts into the muscles of facial expression, including the frown lines.  They work by blocking the nerve transmission between the nerve and the muscle.  This takes several days before the neurotransmitter is completely blocked.

This is not affected by external things like exercise, drinking water or heat.

Dysport works faster than Botox by several days; one can usually see the effect in two days compared to five or more for Botox.  As the days go by, the muscle weakness increases until there is no activation at all of the injected muscles.

Both are excellent products.  Some patients think one or the other lasts longer, but I have heard this from patients about both products, so there may be some individual variation in a person's response.
