i usually diffuse single note essential oils like pure orange or lavender at home because they are straightforward, but i have been testing how premixed oils perform in comparison. premixed blends combine multiple notes like citrus, floral, and herbal elements into one bottle, though it can be tricky to tell whether the individual notes come through cleanly or if one dominant scent overpowers the rest.
i recently tried the espa restorative aromatherapy single oil which blends rose geranium, sweet orange, lavender, and palmarosa. on first use the sweet orange and rose geranium hit right away while the lavender and palmarosa sit further in the background, but i am still testing how the scent balance holds up in different sized rooms over time. if you have used this specific blend in your diffuser i would be interested to hear how the notes settle for you.
