ANUA Heartleaf 80% Moisture Soothing Ampoule

Anua Heartleaf 80% Soothing Ampoule is one of Anua’s best-selling products globally and among the most iconic formulas in the entire K-beauty ampoule category — a deceptively simple, ultra-concentrated soothing ampoule built around a single hero ingredient at an exceptionally high dose: 80% Houttuynia Cordata (Heartleaf) Extract, occupying the first position in the ingredient list and constituting the overwhelming majority of the formula by weight. Everything else in the formulation exists to support, stabilise, and amplify what that 80% Heartleaf base delivers. The texture is watery, silky, and almost weightless — it spreads effortlessly, absorbs almost instantly, and leaves no stickiness, greasiness, or residue of any kind. It preps the skin for the next skincare step beautifully and is versatile enough to be mixed directly into foundation before makeup application for a luminous glass-skin finish. Fragrance-free, paraben-free, non-comedogenic, vegan, and cruelty-free. Clinically tested by OATC Skin Clinical Trials Center (2022): a measurable 4.89% reduction in redness from external irritation after just 2 weeks of daily use in 30 participants. Suitable for all skin types, particularly sensitive, redness-prone, acne-prone, and dehydrated skin. Made in South Korea.

Houttuynia Cordata — known as Heartleaf or Eoseongcho in Korean traditional practice — is a flowering herb native to Southeast Asia and East Asia with a long documented history in both Korean and Chinese herbalism. At 80%, it is not merely present in this formula — it is the formula. Heartleaf Extract’s primary active components are flavonoids (particularly quercitrin and isoquercitrin), which are responsible for its core cosmetic activity: potent inhibition of skin inflammation via suppression of pro-inflammatory cytokine pathways, antibacterial activity against acne-causing bacteria including Cutibacterium acnes, antioxidant protection against free radical and environmental damage, regulation of sebum secretion in oilier skin types, and barrier-supporting hydration through its naturally occurring content of amino acids and fatty acids. At a concentration of 80%, this formula delivers these benefits at a clinically meaningful level that is genuinely distinguishable from products with trace or low-percentage Heartleaf inclusions. Anua sources its Heartleaf domestically from Korean farms, ensuring quality control and freshness. Cassia Obtusifolia Seed Extract — derived from the seeds of the Sicklepod plant, a traditional East Asian medicinal herb — is one of the formula’s most functionally important supporting ingredients. It is an exceptional natural film-forming humectant, rich in galactomannan polysaccharides that create a breathable, moisture-retaining film on the skin surface after application, sealing in the hydration delivered by the other formula actives and shielding the skin barrier from further moisture loss and external irritants. It also has traditionally documented soothing and anti-inflammatory activity that works in synergy with the Heartleaf Extract. Panthenol (Pro-Vitamin B5) is the formula’s primary skin-conditioning and barrier-reinforcing active — it penetrates the upper layers of the skin, converts to Pantothenic Acid, and provides direct moisturisation, anti-inflammatory action, and wound-healing support; it reduces redness, soothes irritation, and reinforces the integrity of the skin barrier to make it more resilient against environmental triggers. Sodium Hyaluronate is the sodium salt form of hyaluronic acid, a powerful humectant that attracts and holds up to 1,000 times its weight in water on the skin surface, delivering immediate plumping and surface hydration that maintains a smooth, dewy complexion. Betaine is a naturally derived sugar beet osmoprotectant and humectant that provides additional soothing, anti-inflammatory, and moisture-balancing properties — it reduces skin sensitivity and environmental reactivity while contributing to the formula’s comfortable, non-sticky skin feel. Glycerin is the formula’s baseline humectant, drawing moisture into all layers of the skin and creating a surface reservoir of hydration that prevents transepidermal water loss. Arginine is an amino acid that contributes to the formula’s pH stability while also providing mild skin-conditioning and barrier-supportive benefits. Hydroxyethylcellulose is a plant-derived natural polymer that gives the formula its characteristic silky, slightly viscous gel-like consistency without adding any heaviness or occlusive weight — it enables the formula to spread smoothly and absorb cleanly while maintaining stable texture. Carbomer (Carbomer-940) is a synthetic polymer that further controls the formula’s rheology and ensures uniform ingredient distribution throughout the gel base.
