Expert Review Summary
The Anua Heartleaf 77 B3Zinc Soothing Serum delivers 77% Houttuynia cordata (heartleaf) flower, leaf, and stem water alongside 5% niacinamide and 1% zinc PCA in a water-thin, non-sticky format designed for oily, acne-prone, and sensitized skin. This serum is formulated specifically for daily sebum regulation, breakout prevention, and post-acne redness reduction. The 77% heartleaf concentration provides a high-strength anti-inflammatory and antimicrobial base that calms active breakouts while the niacinamide and zinc PCA combination targets sebum production, enlarged pores, and post-inflammatory hyperpigmentation. Additional calming agents include panthenol, betaine, trehalose, and sphingomonas ferment extract. Priced around USD 25 for 30ml and available from authorized K-beauty retailers, the serum occupies a niche between general soothing formulas and dedicated acne actives. It is fragrance-free, absorbs within seconds, and can be applied as a first-step serum after cleansing without pilling risk.
