Important discovery made by researchers at ISAS of Trieste: the injections “smoothes wrinkles” have a curious side effect: alter the ability to understand other people’s emotions! The researchers performed a test on a group of women who, prior to receiving treatment, they knew also recognize hints of smiles. AFTER? not anymore!
The effect is particularly marked when the expressions of those who were in front were just mentioned; the explanation is neurological: empathy goes through the expressions that the face takes on when observing others. Since the botulinum toxin paralyzes the muscles, the process hangs!
