- Essential oils and absolutes should remain in their amber glass bottles since ultraviolet light can degrade the aroma.
- Make sure the cap is on tight to prevent oxidation.
- Keep oils at low temperatures, 10° C (50° F) or below. Keep oils in refrigerator for long term storage. Warm and shake gently before use.
- Products are best used within two years with the exception of citrus oils (like bitter orange and mandarin), which should be used within one year.
