There's no denying the fact that even in the most dire economic circumstances, many people will still find money to spend on improving their appearance. Whether they spend on haircuts, makeup or Botox treatments, just because times are tough doesn't mean that they will let their appearance go downhill as well.

In fact, throughout the recent economic difficulty - dubbed the Great Recession - millions of people flocked to plastic surgeons for Botulinum Toxin injections such as Botox and Dysport. According to the American Society of Aesthetic Plastic Surgery (ASAPS), more than 2.4 million individuals underwent these procedures in 2010.

In addition, the popularity of these procedures increased by approximately 50 percent between 2002 and 2010.

Botox has also been the most popular non-surgical cosmetic procedure performed in the U.S. since the year 2000, even though it was not approved for cosmetic use by the U.S. Food and Drug Administration until 2002.

What makes it so popular? According to InjectableSafety.org, Botox and other similar injectables block the nerve impulses that create the muscle contractions responsible for creating expression lines on the face. While the results are not permanent, they last between four and six months and over time treatments may cause the lines to disappear completely.

Neurotoxin injections have no down or recovery time, are inexpensive compared to surgical alternatives and are relatively low-risk. However, complications and serious risks can occur if the injector is not qualified or board-certified in plastic surgery or dermatology.

The maker of Botox, Allergan, has continually reported strong sales figures and many financial analysts say this proves the drug can weather any economic storm.

The fact that it is also FDA-approved for other conditions, including excessive sweating, may also help ensure its performance in the future.
