Botox injections are non-invasive and therefore are very popular with people. With Botox treatment, people can look younger and freshen up their look. A recent study shows that Botox treatments which eliminate wrinkles can also eliminate the ability to show appropriate emotions on your face. 

A study conducted recently showed that people who have taken Botox injections take longer to show emotions like sadness, glaring, or showing sympathy. The slowness of displaying those emotional reactions may lead to lost friendships if people misinterpret the reason for the lack of sympathy or lack of sadness on someone's face.

So Botox may be good for removing wrinkles but make sure that you are aware of its ability to also impact your social life too when people fail to understand why you appear "unsympathetic" in a particularly sad situation.
