20 years ago I tried botox for the creases between my eyebrows.
It did NOTHING. Zero visible effect, even though that is the classic case for botox.
My research prior to that indicated that a botox treatment is good for maybe six months at most, then you redo it. But if you have done the same treatment many times the effect may become permanent and not reversible.
I had not heard of it as a lip "plumping" treatment, but yeah... i read it has some effect to cause the lips to turn out and
appear as if they were larger.
But the mechanism of botox is to weaken the muscle it is injected into. That would be highly undesireable for a brass player, I imagine, as the lips are pretty much all muscle. I guess she needs to wait for it to wear out.
Like-wise for any physical filler that was injected, although
that sounds longer duration.
