Acts like a Moisturizer?
A good moisturizer includes emollients, humectants and occlucives. As some oils work as occlusives also, I was wondering that if someone applies oil (emollient+occlusive) on damp face, would it work somewhat like a moisturizer?
P.s. I know water can’t draw moisture from air as humectants do, but applying oil on damp face may trap water in to benefit the skin?

It is greasy and doesn’t spread well. But if you compare no moisturizer at all or oil over damp skin I vote for oil over damp skin.

If it spreads well, benefit of both will be same?

Some people will use straight vaseline on their face/body for this - to provide that occlusive layer to trap everything in.
I think the reason for opting for an emulsion as opposed to straight up oil is that you can deliver water soluble ingredients that boost water retention but also cut down on the ‘greasiness’ of the oil phase so that it’s more enjoyable and feels better on the skin.
Also humectants tend to not draw significant moisture from the air unless the humidity is quite high. They will however hold water present in the top layers of the skin and potentially draw water from deeper in the skin up towards the surface.
