PIE or PIH?

The marks acne leaves behind come in two kinds — red (vascular) and brown (pigment) — and they need different ingredients. Five quick questions, including the classic press test, tell you which you're dealing with and what actually helps. About 45 seconds. No products, no sales pitch.

Neutral, evidence-graded reference. Not medical advice, diagnosis, or treatment.
