I read somewhere that Botox results become semi-permanent after perhaps 8-12 treatments. Is this true? If so, would it only be true for certain areas or for any area treated with Botox? I'm getting Botox for down-turned corners. Thank you!

Permanant Botox Effect
Botox is a paralytic and thus stops the motion of muscles. The more the muscles go without moving the more they will atrophy or get smaller. Although they will never full go away continues Botox injection will make them very small. Therefore, less Botox is needed to keep the muscle from moving and the longer the effect will last. Stopping the Botox will allow the muscle function to return. It will eventually return to its pre-Botox state.
Repeated use of Botox may weaken but not eliminate muscles
To my knowledge, there are no widely accepted reports of this phenomenon. The muscles may weaken after repeated use but can return to normal after cessation of use.
BOTOX results are usually not permanent
Botox causes weakness of muscles which are causing wrinkles or in your case, downward turning of the corners of the mouth. Over repeated treatments, the muscles will atrophy, provided there is not a long period between the time the effect of Botox wears off and your next injection.
I tell my patients you can think of Botox as a chemical cast on the muscles. Just like when you wear a cast on your leg or arm, the muscles get weak and smaller over time. But when the cast comes off, you can build your muscles back to the same shape they were in before. What you can expect over repeated injections is that the dosing might lessen, and potentially the length between treatments might get longer. In some cases, longer might be 9 months or more, but usually not permanent.

Botox results are not permanent
Botox results are only temporary, and typically last 3-4 months for most people. For those who get injected at regular intervals over time, however, the results can sometimes last a little bit longer, since the muscles have been immobilized for a long period and can atrophy. That said, once Botox use is discontinued, they will slowly return to how they were initially, prior to treatment.
Botox results are not permanent
I am not aware of any scientific reports that find that Botox effects are permanent. With repeated use the muscles that Botox targets may atrophy, but with discontinuation of Botox treatment they should gradually return to normal.
Botox and long term effect
Botox can have a thoeretical longer term effect over time for several reasons. I havent seen any studies concerning this but there are patients who get botox for blepharospasm (spasm of the eyelid muscles) that get a lower dose over the years. The reasons are the following:
1. As muscles become paralyzed they become atrophied or weaker. Thus you may need less botox to paralyze the muscle and even off the botox the muscle may not be as strong as they were before botox
2. Muscle memory - You may learn to not use the muscles injected with botox over time if they are constantly paralyzed.
The botox returns function because the nerve end plates regenerate. It is an irreversible medicine in that the botox binds nerve receptors permanently. Function returns because new nerve receptors grow it. This is regardless of physical activity.
Wikipedia describes how botox works.
Botox results not usually permanent with long term use.
Botox usually works for 3 to 4 months. This depends on the dose, as well as the patient. If the patient is hyper-metabolic, (i.e. in the gym twice a day) it may last a shorter period of time. Likewise if a patient is very animated with the muscles of facial expression, this can also decrease the length of effectiveness.
Some will say that with continued use, the muscle will atrophy and one may use less Botox, or come in less frequently. As of this writing, there are no good medical studies to show this. Therefore we cannot say that Botox is permanent.
