I'm not a dermatologist, but I have visited them on a regular basis. I know my dermatologist would say, "No!" Never apply oil immediately after doing anything dramatic or abrasive to your skin. My dermatologist recommends olive oil to keep my skin soft and supple, but I am to use oil on my skin only if it is in a healthy state. I would say, let the skin heal for a day or two after bleaching and then use oil if you need it.
