[Product Question] Looking to get evening primrose oil today, should I get supplements too? Opinions on the oil for acne-prone skin?

Beauty Tips For Body Care
Wondering if anyone has had luck applying evening primrose oil topically and/or taking supplements. I planned on setting out today to find the oil, but when looking it up I found that people use it as a supplement too. I've seen the supplement form at Trader Joe's before and I'll be there today, anyone have any experience using it to calm acne? What about just the oil applied topically?
