Why Oily Skin Really Does Need a Moisturizer
If you have oily skin, the thought of smearing on more moisture sounds like an unpleasant, and even counterintuitive idea. “I have combination oily skin, and I never really thought I needed a moisturizer,” says New York-based stylist Christine Cameron of My Style Pill.
In fact, many people with oily skin don't think they need a daily moisturizer, but here's why that's a misconception: Oily skin can still be dehydrated. “This is what we refer to as the ‘oil-well in the desert’ syndrome,” says Clinique guiding dermatologist Dr. David Orentreich. “Though sebum—the oil produced from oil glands—may be plentiful, the surrounding skin may be dry. Sebum plays a role in retaining moisture in the surface skin cells; but by itself, it may not be adequate without a humectant, which helps keep water from evaporating.” Basically, oil and water are two different things, and our skin needs both to be healthy.
