With 77% heartleaf extract as its base, this toner delivers concentrated quercetin and flavonoids that directly suppress IL-6 and TNF-α inflammatory pathways — providing measurable redness reduction that resonates with acne-prone and reactive skin.

Formulated with a proprietary heartleaf-derived oil that demonstrated a 22.8% reduction in sebum levels in clinical testing, making it one of the few cleansing oils that actively addresses the sebum excess it removes.

Quercetinol — a bioavailable form of quercetin extracted directly from heartleaf — pairs with BHA to dissolve keratin plugs inside pores while hyaluronic acid prevents the post-cleanse tightness that signals barrier disruption.

Stacking niacinamide's melanosome-transfer inhibition with tranexamic acid's plasmin-blocking mechanism targets hyperpigmentation at two independent pathways simultaneously — an approach shown in studies to outperform either ingredient used alone.
