what is done to botox to make it „safe“ to inject into someone?

Question

I just learned that botox is so toxic that it makes sarin gas look breathable, in fact according to the wikipedia list of toxins ordered by toxicity it is the single most dangerous toxin to life as we know it in the universe so far.

What on earth is done to it so that it can be injected into someones cheeks?

Nothing has been done to it. It does what it’s meant to do, paralyzes the nerves. But when injected cosmetically (or medically), it is done in extremely minute quantities and very precise so it’s localized.
