Botox may make people look younger, but a new study shows it can also lessen the ability to read the emotions of others.

Researchers at Barnard College followed two groups, one that received Botox which dampens facial movements. The other group was a gel that amplified muscular signals.

Both viewed computer images of faces and identified what emotions they saw. Experts found those that received Botox got worse at reading emotions, while the other group got better.

Researchers said the reason is that people read emotions partly by mimicking facial expressions. The study was published in the journal "Emotion."
