The Anua Heartleaf 77% Soothing Toner has dominated Korean beauty rankings, clinching the prestigious Olive Young #1 Toner award for its peerless ability to extinguish skin inflammation, redness, and cystic acne flare-ups. Formulated with 77% pure Houttuynia Cordata (Heartleaf) extract harvested locally in Korea, this featherlight toner delivers immediate botanical relief to inflamed sebaceous glands while gently restoring the skin's acidic mantle to an optimal pH of 5.5–6.0.

Heartleaf contains exceptionally high concentrations of natural flavonoids (quercetin, quercitrin, and hyperoside) that possess potent anti-inflammatory, antimicrobial, and antioxidant properties. When applied to reactive or breakout-prone skin, it swiftly calms angry red blemishes, regulates excess sebum output, and eliminates the stinging tightness commonly caused by harsh foaming cleansers or hot weather. The addition of centella asiatica, panthenol, and sugarcane extract gently sloughs dead surface debris without disrupting delicate barrier lipids.

Its water-like viscosity makes it a masterwork for the famous Korean '7-Skin Method' (layering toner multiple times) or DIY sheet mask toning pads. Pouring this toner onto thin cotton pads and resting them over cheeks and forehead for 5 minutes delivers rapid cooling relief from sunburns, rosacea, and post-shaving burns. With non-comedogenic certification and an ultra-clean EWG Green Grade formula, Anua 77% is the ultimate starting point for anyone seeking balanced, clear, and calm skin.
