1. Storage: Store attars in a cool, dark place away from direct sunlight and extreme temperatures. Heat and light can degrade the quality of the oil.

2. Container: Keep attars in their original containers or bottles, preferably dark-colored glass bottles, which help protect the oil from light.

3. Seal Tightly: Ensure the bottles are sealed tightly to prevent evaporation and contamination.

4. Application: Apply attars directly to the skin. They can be applied to pulse points like the wrists, behind the ears, and the neck. Avoid rubbing the attar after application, as this can alter the scent.

5. Avoid Contamination: Do not mix attars with other perfumes or oils. Use a clean applicator or roll-on to avoid contaminating the oil.

6. Clean Hands: Always wash your hands before applying attar to prevent transferring any dirt or oils into the bottle.

By following these care instructions, you can preserve the quality and fragrance of your attars for a longer period.
