A furocoumarin-free, non-photosensitizing essential oil is an essential oil that does not contain furocoumarins, a group of chemical compounds that are known to cause photosensitivity in some individuals. Photosensitivity is a skin reaction that occurs when certain substances make the skin more sensitive to sunlight, leading to an increased risk of sunburn or skin damage when exposed to UV radiation.
Furocoumarins are naturally occurring compounds found in some citrus essential oils, such as bergamot (Citrus bergamia) and certain types of lime and lemon oils. These compounds can cause skin reactions, including phototoxicity or photoallergic reactions, when applied to the skin and exposed to sunlight.
To create a furocoumarin-free, non-photosensitizing essential oil, manufacturers may use specific processes to remove or reduce furocoumarin content. Bergamot essential oil, for example, can be processed to create a “bergapten-free” version that is less likely to cause photosensitivity.
Essential oils that are furocoumarin-free and non-photosensitizing can be a safer choice for topical use, especially in products intended for skin application.
