omega 3 fish oil

Question:

does this stuff really reduce oily skin and if so how????

I am not sure what gave you the idea that Omega fish oils can reduce oiliness. There is no research indicating such benefit from the fish oil although it does have many other benefits for your health and should be taken as supplement if you don’t eat enough fish. If there is source for what you are describing please provide it and I will gladly research this again.
