Yes! I have very oily skin and didn't moisturize at all until my derm pointed out that my skin was likely reacting to being dried out after cleansing by producing more oil. I started using a very light moisturizer (Clinque's Dramatically Different Moisturizer, which they sadly reformulated and is no longer great for oily skin--I've switched to the gel, which is okay) twice a day and my skin has never been happier. It's counter-intuitive, but in my experience even oily skin needs moisturizer to stay happy.
