Heartleaf, Houttuynia cordata, is K-beauty's quieter calming ingredient, less famous than centella asiatica but arguably more effective for acne-related inflammation. The plant has been used in Korean and Chinese traditional medicine for centuries, primarily as an anti-inflammatory and antimicrobial treatment. It entered modern K-beauty through brands like Abib, which made heartleaf the centerpiece of their acne-focused lineup, and Torriden, which combined it with barrier-repairing actives. What makes heartleaf distinct from centella is its specific efficacy for acne, it addresses the bacterial and inflammatory side of breakouts more directly, while centella is broader in its calming action. For skin that's both acne-prone and sensitive, heartleaf is often the better fit.
What Does Heartleaf (Houttuynia Cordata) Actually Do?
Heartleaf's active compounds include quercetin, hyperin (quercetin-3-galactoside), quercitrin, and decanoyl acetaldehyde, the last of which contributes to its distinctive antimicrobial properties. Quercetin is a flavonoid with potent NF-κB inhibitory activity, reducing the pro-inflammatory cytokine cascade at the gene expression level. It also inhibits C. acnes-induced IL-8 and TNF-α release from keratinocytes, directly addressing the inflammatory response specific to acne. Hyperin has demonstrated inhibitory effects on lipoxygenase, an enzyme involved in the synthesis of pro-inflammatory leukotrienes. The combination of antimicrobial and multi-pathway anti-inflammatory action distinguishes heartleaf from purely soothing botanicals.
Who Should Use Heartleaf (Houttuynia Cordata)?
Acne-prone sensitive skin is heartleaf's ideal territory, it addresses the two central problems (inflammation and bacteria) of that skin combination without adding another strong active that could irritate. Rosacea-prone skin benefits from the NF-κB suppression. If you've been rotating between centella (not enough for acne) and BHA (too harsh for your sensitivity), heartleaf fills the gap between them. Combination skin with reactive T-zones responds particularly well.
How to Add Heartleaf (Houttuynia Cordata) to Your Routine
Use heartleaf serums or essences after toner, before moisturizer. It's gentle enough for morning and evening use. Layer under niacinamide for added oil control and brightening. On nights you're using BHA, apply heartleaf after to calm the skin post-exfoliation. Korean heartleaf cleansers are also worth using as your first or second cleanser, they deposit some of the active compounds onto skin even in rinse-off form.
- When: Morning and evening
- Step: Serum or essence step
- How often: Daily
- Pair with: Niacinamide, centella asiatica, BHA, panthenol
- Avoid: No significant contraindications. As with most botanicals, patch test if you have multiple plant sensitivities.

FAQ
What is the difference between heartleaf and centella for acne?
Centella asiatica is broader, it calms all types of inflammation and focuses heavily on barrier repair. Heartleaf is more specifically targeted at acne-related inflammation, with direct antimicrobial activity against C. acnes and potent NF-κB suppression specific to acne-associated inflammatory pathways.
Can heartleaf be used with BHA for acne?
Yes, heartleaf and BHA are a complementary combination. BHA physically clears pores by dissolving sebum and dead cell buildup; heartleaf suppresses the bacterial and inflammatory response that causes redness and swelling. The two work on different aspects of acne without interfering with each other.
Is heartleaf good for rosacea?
Heartleaf's anti-inflammatory properties are beneficial for rosacea, particularly for the red, inflamed type. The NF-κB inhibition reduces the chronic inflammatory signaling that drives rosacea reactivity. Several Korean brands specifically formulate heartleaf products for sensitive and rosacea-prone skin.
How is heartleaf different from other botanical calming ingredients?
Most botanical calming ingredients (aloe, green tea, licorice) work through one or two anti-inflammatory pathways. Heartleaf addresses bacterial activity AND multiple inflammatory pathways simultaneously, making it particularly effective for acne-prone sensitive skin that needs both calming and antibacterial action.
