Bergamot essential oil (Citrus bergamia) is expressed from the peel of Bergamot oranges. Bergamot has deodorant and antiseptic properties. Its fresh citrus scent gives a lift to perfumes. Be sure to use “bergaptene-free” bergamot in cosmetics. This is bergamot that has been treated so it does not make the skin more sensitive to sunlight, like regular bergamot does.
