Jojoba oil is known to have a long lifespan, and will not expire/go bad for 2 - 3 years on average. When a bottle of jojoba oil is exposed to the air it is more likely to start going bad, so we recommend keeping it in a bottle with a tight lid in a cool area away from direct sunlight. We don’t recommend using jojoba oil if you’ve had it for over 3 years, or if it has discolored/changed in any way.
