Why Heartleaf Went Viral in K-Beauty
Heartleaf (houttuynia cordata) has been a staple in traditional Korean and Japanese herbal medicine for centuries, but it took TikTok and the K-Beauty wave to bring it to global attention. Anua's Heartleaf 77% Soothing Toner became one of the most viral skincare products of the past two years, and for good reason: heartleaf extract delivers powerful anti-inflammatory, antibacterial, and sebum-regulating benefits that show visible results almost immediately.
The plant contains quercetin, quercitrin, and other flavonoids that inhibit inflammatory pathways, making it exceptionally effective for calming red, irritated skin. Unlike some calming ingredients that only mask symptoms, heartleaf addresses the underlying inflammation while simultaneously balancing oil production.
Heartleaf vs. Centella Asiatica: Which Calming Ingredient Is Better?
Both heartleaf and centella asiatica are excellent for sensitive and irritated skin, but they work through different mechanisms. Centella excels at wound healing and collagen regulation, making it better for acne scars and barrier repair. Heartleaf is stronger at immediate calming and oil control, making it the better choice for active breakouts, redness, and combination-oily skin. Many K-Beauty enthusiasts use both — centella in their treatment step and heartleaf in their toner.
