Any Info on Frotox?

I'm sorry, but I have not heard of any information in regards to Frotox.  However, if you have been using Botox for ten years with no problems, I'm not sure why you would switch to something else.  All medications are potentially toxic in the correct doses.  Something as simple as Tylenol can be toxic if enough is taken.  The important aspect of using any drug is using the correct dose.  The amount of Botox used for cosmetic purposes is very safe (as you have seen for yourself).  

The word toxin gets a bad rap.  There's lots of talk on the internet and in health food stores about getting rid of all these toxins.  However, many very helpful and even life-saving medications are "toxins" (i.e. nearly every chemotherapy drug) and any medication, even over the counter or natural, can be toxic in the wrong amount.  Drugs should be judged by their efficacy and side effect profile.  Botox is very effective and safe in the right dose, as you seem to know having used it for 10 years. Back when Botox was originally marketed, it could have just as easily been called a neuromodulator, rather than a neurotoxin, which would accurately describe what it does and not be as scary.  Hindsight is 20/20.
