4% betaine salicylate — a gentler salicylic-acid equivalent derived from sugar beet — with niacinamide and willow bark water. Better tolerated than a straight 2% BHA, though effectively similar in function for surface blackheads and congestion.

A straightforward 2% BHA in a lightweight watery base with a little witch hazel. Effective pore and blackhead exfoliation at a rock-bottom price; the simple base means less of the soothing buffer found in pricier BHAs.
