Acne Scars vs. PIH: What’s the Difference?
Here’s the simple way we explain it: true acne scars change the skin’s texture (think tiny pits, dents, or raised areas). PIH—post-inflammatory hyperpigmentation—looks like flat brown or pink spots that linger after a breakout. Many patients in Madison call these “acne scars,” but they’re not technically scars; they’re pigment left behind by inflammation, sometimes nicknamed pseudo scarring.
