Confession: there was a good stretch of time where I was skipping moisturizer completely because of my oily skin. But the irony in this is forgoing moisturizer dries out your skin, making it produce more sebum. I love Hada Labo Skin Plumping Gel Cream ($25) because it's a gel, so it doesn't leave a greasy residue on my skin. Hyaluronic acid plumps your skin and keeps it smooth by absorbing moisture from the air around you while strengthening your skin's natural hydration levels. I've even turned my younger brother onto this stuff . . . that's how much I'm obsessed with it.
