The phototoxicity of the psoralens found in cold-pressed bergamot essential oil, especially the psoralen bergapten, is a drawback in most situations. However, it can be medically useful in the treatment of some skin conditions, including vitiligo, eczema, and psoriasis. For example, people undergoing psoralen and UVA (PUVA) therapy take psoralens orally or apply them topically, then expose skin to UVA light. Cases of second-degree burns due to PUVA therapy have been reported; this therapy should only be done under medical supervision.[1][2]
Can the photosensitizing property of psoralens found in bergamot be medically useful?
