  • When you inject Botox into your muscles, it reduces the functioning of your muscles and puts them in a state of some form of paralysis. This is an intended function of Botox because, when the muscles become weak, it helps to delay and reduce the signs of aging.
  • When done over a period of time, and when the Botox injections are taken for a long time, it can lead to a loss of control in the muscles. This also reduces the overall strength of the muscles in the particular area where the Botox is injected.
  • When these injections are administered in the same area over and over again, it can lead to permanent paralysis in that particular muscle.
