A group of scientists presented a study at the 61st Annual American Academy of Dermatology meeting showing that men need twice the amount of Botox® than women do to achieve similar results. The researchers found that the reason why men need more Botox® is due the greater thickness and muscle tone of male skin.

Getting rid of wrinkles can surely make anyone happy. A recent study finds that Botox® gives patients a whole new reason to smile.  The study, performed by the University of Wisconsin, found that by using Botox® to prevent the facial expression of negative emotions your brain is therefore tricked into thinking that those emotions don’t exist.
