Essential oils and fragrance oils are not the same thing, and the industry treats them like they are.
Essential oils are pulled straight from plants -- steam-distilled, cold-pressed -- carrying that plant’s actual chemistry: terpenes, esters, aldehydes. They vary by harvest, region, season. Complex and alive.
Fragrance oils are built in a lab to smell like something. Consistent, stable, cheap, and completely divorced from any plant.
A fragrance oil that smells like rose contains no rose. It’s synthetic molecules engineered to approximate the scent.
Both can react with sensitive skin. Both can appear on a label without saying which they are -- “rose fragrance” could be either.
Why it matters beyond honesty: essential oils carry the plant’s real compounds. A properly distilled lavender holds linalool, linalyl acetate and dozens more. A synthetic lavender smells identical and holds none of them.
Real essential oils get listed by name. If you see “fragrance” instead, you’re smelling a lab, not a plant.
