Zurich University and the Swiss Federal Institute of Technology are offering free Botox to volunteers to a study that aims to study the anti-wrinkle drug’s effects.

According to reports, the research companies have released ads asking people if they’ve ever tried Botox.

Researchers claim that they’ve already found five volunteers, but they’re still looking for 25 more people. In addition to free Botox, volunteers also get an undisclosed amount of money.

Dr. Arko Ghosh, the lead researcher of the study, intends to study the effects of Botox in brain activity.

No current research has been done on the actual effects of Botox on the brain.
