I really don't have problems with my skin, maybe just the occasional dryness.

Also, if you have to use your computer to refer back to the
drawing, I suggest magnifying the drawing to fit the screen (175 or 200% works great, but then again, I have a netbook computer),
and pushing the F11 key to hide all the toolbars and the URL box (press
F11 again to get them back). This is an easy process of
the swishing of oil inside the mouth for 15 to 20 minutes.
