Heartleaf : l'ingrédient apaisant star de la K-Beauty

Heartleaf calms redness, regulates sebum, and strengthens the skin barrier. In Korean, it's called 어성초 (eoseongcho), and botanically, Houttuynia cordata. In France, its name is less known than its effects, but that's quickly changing: this plant active is now at the heart of some of the most sought-after Anua skincare products on the market.

If you're hearing about heartleaf everywhere and want to know what it concretely does for your skin, who it's really suitable for, and how to integrate it into your routine, you've come to the right place.

What exactly is heartleaf? 🌿

Heartleaf is an aquatic plant native to Southeast Asia, used for centuries in traditional Korean, Japanese, and Chinese medicine. Its botanical name, Houttuynia cordata, refers to a plant with heart-shaped leaves, earning it its English nickname "heartleaf."

In cosmetic formulas, it's the extract of its leaves that is used, often designated on INCI labels as Houttuynia Cordata Extract. This extract contains flavonoids, alkaloids, and polyphenols, which explain its documented anti-inflammatory properties.

A study published in the Journal of Ethnopharmacology (Source: to be added manually) confirmed that Houttuynia cordata extract inhibits pro-inflammatory pathways, including the production of cytokines involved in skin reactions. Concretely: your skin reacts less, reddens less, and recovers faster after aggression.

 

The benefits of heartleaf for the skin 💧

 

Heartleaf acts on several mechanisms at once, making it particularly versatile.

Anti-inflammatory: this is its main action. The flavonoids it contains block inflammation mediators, visibly reducing redness and irritation within a few applications. On skin prone to inflammatory acne, the effect is generally noticeable within 2 to 4 weeks of regular use.

Antioxidant: heartleaf's polyphenols neutralize free radicals produced by UV exposure and pollution. Result: skin ages slower and its radiance is better preserved.

Sebum regulation: heartleaf acts on the sebaceous glands to limit their excessive production. For oily skin, this translates to reduced shine and less visible pores over time.

Purifying: its natural antibacterial properties make it an ally for acne-prone skin. It limits the proliferation of Cutibacterium acnes, the bacteria involved in pimple formation.

Hydrating: contrary to what one might think for a "purifying" active, heartleaf does not dry out the skin. It helps maintain the hydration of the skin barrier while treating imperfections.

Expert tip: many believe that heartleaf is only for acne-prone skin. This is a common mistake. Its anti-inflammatory action and skin tolerance make it equally relevant for sensitive, rosacea-prone, or simply reactive skin. Confusing it with an "acne treatment" active means missing out on half of its benefits.

 

Who is it really for? 🎯

 

Heartleaf is one of the few K-Beauty actives you can recommend for almost all skin types, with some important nuances.

Skin type Relevance What it concretely changes
Oily / combination skin Very high Reduces sebum, tightens pores, limits blackheads
Acne-prone skin Very high Antibacterial + anti-inflammatory action on active pimples
Sensitive / reactive skin High Calms redness, strengthens skin tolerance
Normal skin Moderate Preventive antioxidant, maintains radiance
Dry skin Moderate (to be combined) Soothing, but to be combined with nourishing actives


Heartleaf is suitable for oily skin that doesn't want harsh actives, for sensitive skin that reacts poorly to BHAs or acids, and for anyone seeking an anti-redness action without a dermatological prescription.

However, if your skin is very dry and fragile, heartleaf alone will not be enough. It needs to be accompanied by occlusive or emollient actives to compensate.

 

How to use heartleaf in your routine? ⏱️

 

Heartleaf is found in almost every step of a Korean routine: toners, cleansing oils, foams, serums, creams, and even sunscreens. This is what distinguishes it from many actives.

The Korean brand Anua has made it its signature ingredient. The Anua Heartleaf Pore Control Cleansing Oil is one of the most popular heartleaf products in France: the cleansing oil doubles as a first soothing treatment, removing makeup while calming the skin. It's a good entry point if you want to test the active without reorganizing your entire routine.

For a more targeted action, the Anua Heartleaf 77 Soothing Toner contains 77% heartleaf extract, a concentration well above average. Applied after cleansing, it prepares the skin to absorb subsequent treatments while immediately calming it.

If you want to discover how to build a complete Korean routine around soothing actives, the article on why Koreans have beautiful skin provides good basics on the philosophy of layered skincare.

Practical rule: you can use heartleaf morning and night, in almost all formulations. It does not cause photosensitivity, does not react to UV, and does not require an acclimation phase.

 

What actives to combine, what actives to avoid? 🔬

 

Heartleaf is one of the best-tolerated actives in K-Beauty. It has very few association conflicts, which facilitates its integration into an existing routine.

Recommended associations:

  • Niacinamide: synergy on sebum control and evening out skin tone. The two actives reinforce each other without canceling each other out.
  • Centella asiatica: double soothing and repairing action. Ideal for very reactive or post-acne skin.
  • Hyaluronic acid: heartleaf soothes, hyaluronic acid deeply hydrates. A logical combination for combination to oily skin that wants hydration without greasiness.
  • BHA (salicylic acid): heartleaf compensates for the potential irritation of BHAs on sensitive skin. To be integrated into the same routine, not in the same formula.

Associations to avoid or monitor:

  • Strong retinol: if your skin is already irritated by retinol, adding heartleaf is safe, but the active alone will not be able to compensate for the irritations of a strong retinoid.
  • Heartleaf has no known contraindications with AHA acids or stable vitamin C. Associations are generally safe if the textures are well chosen.

How long does it take to see results? 📅

Heartleaf is not an active with immediate visible effects like vitamin C or retinol. Its action is gradual and cumulative.

From the first few days: immediate reduction in redness, feeling of soothed skin. Skin comfort improves rapidly, especially after a phase of irritation or an acne breakout.

2 to 4 weeks: visible reduction in recurring imperfections, less dilated pores, more even texture. It is at this stage that the sebum-regulating action becomes measurable.

6 to 8 weeks: results on inflammatory acne and chronic redness are established. Skin tone is evened out, skin reacts less to external aggressions.

Regularity is key. A one-off application after a pimple will yield few results. Integrating it into a daily routine, morning and evening, over several weeks, is where heartleaf reveals its true potential.

 

What we remember about heartleaf 🌱

 

Heartleaf is a versatile, well-tolerated ingredient backed by solid scientific data. It soothes inflammation, regulates sebum, and protects the skin barrier without aggression. Its strength: integrating into a routine without reorganizing everything.

Three key takeaways: it suits almost all skin types, it has no associated photosensitivity, and results require regularity rather than high doses.
