A recent study found that Botox injections, used to smooth out fine lines and wrinkles, may dampen or cull people’s emotions.
[quote]The study, published in the journal Emotions, found that those who received Botox injections reported less emotional response to some emotional video clips, and as a result, did not feel their emotions quite as deeply as their counterparts.[/quote]
This dampened emotional reaction was only related to mildly emotional clips, suggesting that the strength of the emotional impulse may make a difference.
The new research is further proof of the facial feedback hypothesis. This hypothesis suggests that our facial expressions can affect our emotions via expression or laughter triggers in the skin and facial muscles.
