Do Botox Results Change In Cold Weather?

Although anything is plausible, it's not likely that cold weather is causing frequent changes in your ability to  contract muscles that were previously treated with Botox. A more likely explanation may be that you are actively using these muscles more so when cold and uncomfortable.  If this is the case, you may benefit from higher dosing.  However, if you are not able to replicate the same muscle function when attempting to animate while in a warmer climate, then the answer is yet to be determined.  Interesting nonetheless.

 

There may be issues about Botox's clinical effects that are not yet known or understood. Your symptom of more muscle movement in the forehead when you're exposed to very cold weather may be real for you, but I had not heard of this before.  There may be some medical basis for it as neurologists and ophthalmologists may be aware of the ice test for myasthenia gravis, a neurologic condition that involves the same neurotransmitter that is blocked by Botox. The ice can temporarily improve nerve-muscle communication in myasthenia gravis.  In this condition, upper eyelids are known to droop during stress and as the day gets long.  An ice pack held over the eye for as little as two minutes can make the droop go away temporarily.  You may be showing a nature's way of mimicking the ice pack test by improving your neuromuscular communication until you go inside. Thank you for sharing this with us. Physicians learn from listening to patients.

It has been observed that neuomuscular cooling increases nerve conduction.  This observation is the basis for the so-called "Ice Test." for myasthenia gravis, a neuromuscular disorder.  Could cool of the muscle after BOTOX treatment be the basis for your observation?  It sure is an interesting question.  My advise is to come in from the cold.
