How long does a 2 oz bottle of beard oil last?

Across verified-purchase reviewers, a 2 oz bottle typically lasts 2–4 months at 3–6 drops per day on a medium beard. Longer beards using more product per application report closer to 6–8 weeks. r/beardoil threads also flag that oils can go rancid after roughly a year, so buying bigger sizes isn't always better value.
