Karuna will hand over a full firming serum (a $23 value) if you play along with its Ambassador Program. Make an account, knock out activities in the Actions section until you hit 250 points, then redeem the Welcome Gift under Rewards. It's only for the first 50 qualifying ambassadors, so the catch is a little homework.

“A genuinely free full-size serum with high retail value, but severely hampered by limited availability, multi-step claiming process, and third-party platform hosting.”
