Anua Heartleaf 77 B3Zinc Soothing Serum

The Anua Heartleaf 77 B3Zinc Soothing Serum centers on 77% Houttuynia Cordata Flower, Leaf, and Stem Water (heartleaf), a Korean herbal extract with established anti-inflammatory and antimicrobial properties. At this high concentration, the heartleaf base provides intensive calming for reactive, redness-prone, and acne-adjacent skin while creating an ultra-hydrating environment for active ingredient delivery. The formula stacks 5% niacinamide (vitamin B3) for tone evening, pore blurring, and mild sebum regulation with 1% Zinc PCA, which directly targets sebaceous activity and reduces oil overproduction at the follicle level. Panthenol, glycerin, and trehalose contribute humectant depth, while sphingomonas ferment extract reinforces the skin microbiome. The complete formula contains no synthetic fragrances, essential oils, or known sensitizers. At USD 42.50 for 30ml, this serum is positioned for skin-sensitive users who also need active pore and sebum management from one product. It performs as the first serum in K-beauty layering, sits under any moisturizer without interference, and is a natural fit for reactive, oily, or combination skin types that require both calming and oil control simultaneously.
