Isn’t bergamot oil phototoxic unless explicitly stated as bergapten-free/furanocoumarin-free? Why is it listed as only a 1 in safety?
The essential oil coming from the fruit (probably the rind) of the bergamot orange. It's a common top note in perfumes and contains (among others) fragrant compounds limonene (37%), linalyl acetate (30%) and linalool (8.8%).
A well-known issue with bergamot oil (apart from the fragrance allergens) is that it contains phototoxic compounds called furanocoumarins, but more and more commonly furanocoumarin-free versions are used in cosmetic products. Still, if you have sensitive skin and prefer fragrance-free products, bergamot oil is not for you.
