It is most likely that your pump has hit an air section. We’ve had a few issues reported with the EYES, SERUM, and ACNE, but most guys can get it working by following Aaron’s instructions on our YouTube channel.
Here's how to prime the pump:
1) Make sure the bottle is standing upright
2) Pump for approximately 1 minute, or until the product dispenses.
Please let us know if this solves the issue.
