Should your skin care change when you wear a mask? It's important to apply a lightweight moisturizer, even if your skin tends to be oily. "Skin hydration and skin oil production are separate issues," explains Dr. Zeichner. "Even acne-prone people may need a moisturizer. Especially if you're wearing a mask, you want to make sure your skin barrier is in the best shape possible, which means it's both balanced and hydrated."
