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.

What's actually doing the work
Salicylic Acid
BHA / Beta Hydroxy Acid
Acid
The only BHA widely used in skincare and the gold standard for acne and congested skin. Oil-soluble — penetrates sebum-filled pores to dissolve plugs and exfoliate pore walls. Dual surface + pore-level action uniquely effective for blackheads, whiteheads and inflammatory acne. At 0.5–1% in cleansers it provides daily maintenance without irritation.
Niacinamide
Vitamin B3 / Nicotinamide
Vitamin
The most versatile and universally tolerated skincare active. Inhibits melanin transfer (fading dark spots), reduces sebum by up to 68%, strengthens the skin barrier via ceramide synthesis, calms inflammatory pathways to reduce redness, and visibly minimises pores over 4–8 weeks. Works at any pH and pairs with virtually every other active.
