Lavender is the oil most people start with, and the one that gets used up fastest. Diffuse it at your desk or by the bed, dilute it with a carrier oil for massage, or work a few drops into soaps, bath oils, linen sprays and your own skincare recipes.

Steam-distilled from Lavandula angustifolia flowers, with lavender oil as the only ingredient on the label. Rocky Mountain Oils runs an independent GC/MS test on every batch — enter the batch number from your bottle on their site and you can read the report for the exact oil you're holding.

Blending — lavender sits in the top-to-middle range and softens almost anything. It pairs particularly well with bergamot, frankincense and ylang ylang.

Storing it here — heat and light are what age an essential oil, and Singapore supplies plenty of both. Keep it capped, upright and out of the sun. A drawer or cupboard beats a bathroom shelf or a windowsill.
