Burn the candle for approximately 1.5 to 2.5 hours per session. By that point, the wax pool has fully formed and the fragrance has diffused evenly through the room. This is when the scent is performing at full strength.

Your brain doesn't respond to scent instantly. It takes time to register, settle, and begin influencing your mood and arousal. The first 20 to 30 minutes are the warm up. The fragrance is building, and so is your body's response to it. By the 1.5 hour mark, the scent has fully saturated the space and your nervous system has had time to absorb it. This is when the composition starts to do what it was designed to do.

You can burn it longer if you'd like. There's no harm in it. But the effect doesn't wait until you blow it out. It's already working.
