Botox Can Affect Your Emotions

It has long been suggested that feedback signals from facial muscles influence emotional experience. The recent surge in use of botulinum toxin (BTX) to induce temporary muscle paralysis offers a unique opportunity to directly test this “facial feedback hypothesis.” Previous research shows that the lack of facial muscle feedback due to BTX-induced paralysis influences subjective reports of emotional experience, as well as brain activity associated with the imitation of emotional facial expressions. However, it remains to be seen whether facial muscle paralysis affects brain activity, especially the amygdala, which is known to be responsive to the perception of emotion in others. Further, it is unknown whether these neural changes are permanent or whether they revert to their original state after the effects of BTX have subsided. The present study sought to address these questions by using functional magnetic resonance imaging to measure neural responses to angry and happy facial expressions in the presence or absence of facial paralysis. Results Consistent with previous research, amygdala activity was greater in response to angry compared to happy faces …

Botox in a Bottle?

Can a cream have the same effect as botox? Right now, that’s a tricky question. In the past, the answer has always been a categorical no. If a beautician or department store sales assistant tries to hit you with the phrase “this is a miracle cream – it’s like botox in a bottle”, don’t believe them. Botulinum toxin injections, or botox as we’ve come to know them, work by paralysing the facial muscles, and so far manufacturers haven’t been able to recreate this effect with topical skincare, in part because the molecules of botulinum toxin solutions are too big to penetrate the skin barrier. Despite all this, there have been mumblings among pioneers in the aesthetics industry that topical botox may not be that far off. A pharmaceutical company in the US, Revance Therapeutics, is currently putting a botulinum toxin gel through stage three clinical trials for treatment of crows’ feet, and is expecting results in 2016. That’s not to say that there aren’t powerful topical products out there that can have a visible effect …
