What’s the literature on fish oil?

I’ve read a lot into fish oil and the literature that comes out to date and what not but I just cant seem to figure it out. Although, I do think that a high fish oil diet causes liver inflammation due to personal experience and sometimes getting broken out with acne after a mega dose of 4 grams and more. The gist is that there are studies indicating a high fish oil diet with liver inflammation and on the contrary, the opposite in some regards. I tend to take 4 grams for its antidepressant effects and more but over time, my eyes look tired and my skin breaks out. Could this be me or is the literature correct as it states? I take Wiley’s Finest from Whole Foods. Seems reputable and good! What do you guys think?
