Will Botox Ever Cause Deformities or Permanent Bruising or Muscle Destruction if Used on a Long-long-term?

When performed properly by a board certified physician, Botox is safe and can yield a great result. It will not cause any permanent bruising or destruction to muscle. When looking to have Botox, be sure to choose an experienced and board certified plastic surgeon, facial plastic surgeon, or dermatologist. They are all great choices. I hope this helps, and I wish you the best of luck!

I would recommend you visiting the website for cosmetic Botox, to read about their studies and results of long-term use.

Long term use of Botox to soften facial lines is very safe. Repeated injections of Botox over several years will weaken and atrophy muscles of facial expression, but not in a detrimental way. Botox and filler injections do not cause permanent bruising. 

I have been treating with BOTOX since 1988.  It is a very safe product.  It does not cause permanent bruising or long term damage to muscles.  Like anything, it does help to go to injectors who really know what they are doing.  

Botox, like any injection, can cause temporary bruising, but this should not be permanent.  Botox works by weakening the muscle into which it is injected.  This effect is temporary and does not cause any permanent deformity to the muscle.
