Eli5 Skin aging: how does oil keep it young?

If we constantly replace skin, why should it matter if we oil the top layer? Why doesn’t putting oil on daily affect your skin when you get older?

Your skin is a living thing and it uses natural oils that your body produces to stay supple and healthy so putting oil on your skin is just a little bonus nutrients for it. It’s the same reason people oil up leather, because it too was a living thing at one point so keeping leather oiled makes it soft and playable just like it was skin again. Same principle.
