The Anua Heartleaf 70 Soothing Collagen Mask is a sheet mask from Anua's Heartleaf 70 line — the brand's hero soothing range built on Houttuynia Cordata (heartleaf) at a 70%+ concentration. The mask sheet starts visibly green (from Chromium Oxide mineral pigment) and fades to transparent during wear, providing a visual cue for when the essence has absorbed and the mask is ready to remove.

With heartleaf water as the first ingredient, over 70% of the essence is the anti-inflammatory botanical rather than plain water — delivering a concentrated dose of heartleaf's calming, antibacterial, and barrier-supporting compounds directly to the skin during the 10–20 minute wear. Houttuynia Cordata Extract is also listed separately, providing additional concentrated heartleaf extract alongside the water base.

Soluble Collagen plumps and smooths fine lines on contact. Triple Hyaluronic Acid hydrates at multiple depths. Dipotassium Glycyrrhizate (licorice) soothes and brightens. Saccharomyces Ferment conditions and supports the barrier. Allantoin, Aloe, Lotus Leaf (Nelumbo Nucifera), and Japanese Cedar Leaf (Cryptomeria Japonica) complete the soothing botanical layer. Adenosine provides anti-ageing support.

Menthoxypropanediol and Menthyl Lactate create the cooling sensation — note these are menthol derivatives, so this mask is not suitable for menthol-sensitive skin. Fragrance-free, silicone-free, paraben-free. Reef safe. Cruelty-free.
