Botox for crow's feel is extremely simple and painless procedure. The effects generally last approximately three months. If you decide not to re-treat the area after three months the wrinkles will return exactly as they were before.
On average, Botox reduces the appearance of fine lines and
wrinkles for about 3 months. If you do not get a Botox touch-up after this
three month period, the fine lines and wrinkles that were treated will become
more prominent and appear as they did prior to getting your treatment.
Wrinkle progression without Botox Touchups
If you do not receive what you refer to as "Botox touchups," the muscles previously paralyzed by Botox will return to their normal previous function. Over time that will cause the previous skin wrinkles to return. The wrinkles won't be worse than they would otherwise have been had you not used Botox. The best way to prevent wrinkles in the first place is to avoid sun exposure and cigarette smoking.
