Olive oil soap is hypoallergenic, so you are less likely to experience an allergic reaction when using it. A 2008 publication of "Pediatric Dermatology" found that olive oil was a suitable ingredient in creams used on pre-term infants. If it's safe for the skin of these newborns, it is likely to be gentle on your sensitive skin. Most olive oil soap contains only natural ingredients, as opposed to many other soaps that contain sodium laurel sulfate, a known skin irritant and potential toxin.
