The most common reason Botox doesn't work is that not enough was administered. Botox isn't a one-size-fits-all treatment and the same dose doesn't work for everyone. Some people may need additional Botox to achieve an effective level of muscle weakness. Botox can also be old, overdiluted, or fake.
When it comes to wrinkles and fine lines, many people assume that a few injections of Botox will be enough to remove these unwanted imperfections from their face. In reality, Botox injections temporarily relax the underlying facial muscles and cause wrinkles to recede. However, it may not be as effective in people with non-dynamic wrinkles, such as wrinkles caused by gravity, skin infections, or sun damage. Botox side effects are relatively rare, but as with any cosmetic procedure, they can still occur.
In short, Botox works almost everywhere in the world and for most people, the results are long-lasting and impressive. People who are pregnant, breastfeeding, or suffering from neurological disorders cannot receive Botox injections. Keep in mind that the success of Botox injections depends heavily on technique, and it's also entirely possible to get a “bad batch” that is less than fresh (and therefore less effective). Since the explosion in Botox use, researchers and healthcare providers are realizing that resistance to Botox can develop, and even that there may be some who are completely immune to its effects.
When used early in the aging process, Botox not only treats wrinkles but also prevents new wrinkles from forming. Other uses of Botox are as the first FDA-approved intramuscular preventive treatment for chronic migraines in the United States. If you still don't get results, then you might be one of those rare people who is “immune to Botox”. The effects of Botox will gradually fade over the next four to six months and wrinkles will need to recede. Many people arrive at their Botox appointment with the vague idea that it could be painful and that a needle would probably be involved.
However, Botox injections usually resolve on their own so the results are best seen in about two weeks after the initial treatment. Botox is manufactured in a regulated laboratory setting and is administered in small therapeutic doses, initially to treat blepharospasm (eye spasm) and strabismus (misalignment of the eye).
