How should I store the bottle to make sure the oil lasts and stays effective?

To preserve the quality and aromatic strength of your tea tree oil, store the bottle in a cool, dark place away from direct sunlight and heat sources, like a cupboard or drawer. The volatile compounds that give the oil its scent and properties can degrade when exposed to light, heat, and oxygen over time. The dark glass bottle it comes in helps, but extra protection is beneficial.

Always ensure the cap is tightly closed immediately after use to minimize oxidation. Avoid storing it in humid environments like a bathroom cabinet where temperature fluctuates widely. Under proper storage conditions, an unopened bottle can maintain its quality for several years. Once opened, try to use it within 1–2 years for the best aromatic experience. You may notice the scent gradually becoming milder as it ages, which is normal for pure essential oils. Keep it out of reach of children and pets.
