I came back to the studio today and some piles mixed tube colors of oil paint from yesterday have now 'skinned over,' though the paint below stil seems fresh and usable.
Is it problematic to use this paint, removing the dried skin, and painting with as usual?
Does the paint below have the same properties as paint left on the palette without the skinning, or has the complexity of the oxidation of the oil now made this paint different somehow and less desirable, perhpas more lean...?

We feel that it is "ok" to use the paint inside IF it is still wet AND if you do not incorporate any of the "skin".....the latter is harder to do. Realize that even though the paint beneath the skin, even if it is still wet, has probably begun to oxidize to some degree but you can still work with it to a degree.
To be clear, it is always important to use fresh paint.
Ralph Mayer has a very good section on this in his The Artists’ Handbook. The
degree of importance varies from medium to medium. Obviously, for traditional
watercolor and gouache, the issue is of little importance as the paint is
completely resoluble. It is paramount in egg tempera.. It is in the middle for oil paint. The issue is that you want the paint
to go through its whole drying or setting curve in place and not interrupt that,
which can diminish adhesion. This is different from adding partially pre-polymerized/oxidized
mediums like thickened linseed oil as these are in addition to the amount of
binder need to adequately produce a serviceable paint.
While there are
certainly examples of modern and post-modern artists incorporating paint skins
into their works, I would caution against it unless that is the specific effect
that you are searching for and not just a result of your attempts at economy.
