Why does popping pimples leave scarring?

Why does popping pimples leave scarring when things like minor cuts/abrasions don't? For instance, I've gotten small cuts on my face before and they heal fine leaving no scar; but I pop one tiny little pimple and I'm left with an eternal reminder.

It’s because acne is inherently an inflammatory process. The inflammation associated with the acne pustule causes a different kind of collagen to be formed at the site of healing that more easily leads to a scar. The key is the inflammation deep inside the hair follicle.
