  intro: "Congestion — the blackheads, the visible pores, the subtle surface blockages across the nose and chin — is sebum doing what sebum does, then oxidising on contact with air. It isn't a hygiene issue. It isn't caused by touching your face occasionally. It's mostly driven by pore size (which you inherit), sebum production rate, and whether your routine is regularly clearing what accumulates. Salicylic acid is the most effective ingredient here: it's oil-soluble, so it works inside the pore rather than just on the surface. Double-cleansing matters more than single-cleansing. And the hands-off rule — not squeezing, not picking — is the single most effective prevention against congestion becoming something worse. Below is everything we've published on the subject.",

It's distinct from acne as a condition: congestion describes the sebum and surface buildup, not an inflammatory or bacterial process. The two can coexist, but they respond to different things.",
