I have very oily skin, too. However, last year, following the advice of skincare addiction on reddit, I started using a nightly moisturizer. To my utter shock, my skin has been dramatically less oily. Over the summer my skin looked dewy instead of slick and making my hair gross, etc. I have two theories. One is that, while I didn’t think I was using products to strip my skin of oil, perhaps I was and my skin had upped the oil production to stay hydrated. Or, I’m in my late thirties and coincidentally my skin is naturally cutting back on the oil. @Zella now would be a great time to see if it works for you.
