Where this comes up
The notes BeautySignal puts beside this ingredient when it is on a label.
- Contains fragrance
This product contains fragrance. Fragrance is one of the more common causes of contact irritation, which is why many people prefer to avoid it.
Why we mention it
Fragrance is the most frequently cited preference in cosmetics, and "parfum" on a label can cover many undisclosed components.
- Contains essential oils
This product contains plant-derived essential oils, which carry their own naturally occurring fragrance components.
Why we mention it
Essential oils are often chosen as a "natural" alternative to fragrance, but they contain fragrance compounds themselves, so people avoiding fragrance usually want to know.
What we don't know
