There are sheet masks that hydrate, and then there are sheet masks that are 80% the active ingredient itself. The Anua Heartleaf 80 Moisture Soothing Ampoule Mask belongs firmly to the second category: the primary ingredient in this formula is not water — it is Houttuynia Cordata Flower/Leaf/Stem Extract at a concentration of 80%, making this one of the highest-concentration heartleaf masks available in Korean skincare. Houttuynia Cordata, known as heartleaf, is a plant extract with clinically documented anti-inflammatory, antibacterial, and antioxidant properties. At 80% of the formula, it is not present as a supporting active — it is the medium the essence operates in, delivering an unprecedented level of soothing activity with each application. The formula is mildly acidic and pH-balanced to protect the skin's acid mantle while the essence is being absorbed, a detail that distinguishes high-quality Korean masks from their less carefully formulated counterparts. Triple hyaluronic acid — Sodium Hyaluronate, Hydrolyzed Hyaluronic Acid, and Sodium Acetylated Hyaluronate — delivers layered hydration at different molecular depths, from the surface to the deeper epidermal layers. Allantoin and Panthenol provide additional soothing activity and promote comfortable skin renewal, while Betaine and Biosaccharide Gum-1 lock in moisture and support a calm microbiome environment on the skin surface. Cocoa Extract provides antioxidant protection. The vegan sheet adheres seamlessly to the face for efficient, rapid delivery of the ampoule-concentration essence.
