This oil, while steam distilled, is not considered bergapten-free (FCF*). Steam distilled Lemon oil does have considerably fewer photosensitizing compounds than cold pressed Lemon (<50 ppm for distilled Lemon vs. 5000 ppm for cold pressed). For comparison, a typical Bergamot FCF contains <15 ppm, so there are still enough photosensitizing elements to merit using discretion if using distilled Lemon in topical applications.[1]

Citrus limon is native to Asia and is thought to be a hybrid of citron (C. medica) and pomelo (C. maxima).[2] The fresh, optimistic aroma is instantly recognizable, like seeing a familiar face in a crowd of strangers. These very personal associations may create impressions that last a lifetime and influence use. The aroma of Lemon is widely used in perfumes, cosmetics, soaps and household products.[3] It is wonderful to use in a diffuser while studying or to smell during long drives. Please use Lemon oil on the skin with caution and in low dilution due to the phototoxic effect of citrus oils.

*FCF (furanocoumarin-free) is an acronym that indicates the chemical constituent(s) responsible for extreme sensitization of the skin to sunlight has been removed, in the case of Lemon oil, the specific furanocoumarin being bergapten. This oil, while steam distilled, is not considered bergapten-free.
