Ikea desk...skin trails?

I recently bought a powered up/down standing desk from Ikea. It's great, I like it.

However, it's a dark wood finish, and when my arms are resting on the surface, it eventually develops what I can only assume are skin tracks. See pictures. These appear after minutes (not hours) of general work.

I don't wear any lotions, and am clean. I don't have any skin conditions (exema, etc.)

These wipe off easily, but my question is:

Is there any kind of sealant or protective coating I can apply to the desk service, so I'm not wiping it with a damp cloth every few hours?
