I have a friend who has impeccable skin. No really, she has the kind of skin that prompts strangers to approach her in public and inquire about her skincare regimen. She's always very modest, thanks him or her, and then describes her routine. It's nothing mind-blowing — she's likely blessed with good genes, she just cleanses, tones, and moisturizes (with sunscreen) — but her secret, she swears, is that she changes her pillowcase nightly.

Now that seems a little extreme to me, and not very environmentally friendly, but her skin is amazing, and maybe the proof is in the pudding. So tell me, are you a frequent changer, like my friend, or do you linger in between washes?
