Hands are a different color than my arms?

So I noticed, after I used this cream on my hands (it's a body cream, but I figured it would be fine to use it on my hands too, even though I later read on the packaging that you should wash your hands after use, which I didn't do because it wouldn't make sense lol to put it all over your hands and then wash your hands)., and in the beginning my hands were very soft and still had the same color as my arms, but now they are a little lighter o_O not alot, just a little, but it annoys me and it's been like this for a few months now... Does someone know why this is, and if they will ever go back to the same color as my arms? I don't use the cream anymore btw..
