The Anua Heartleaf 77% Soothing Toner has established itself as one of the most popular Korean toners for sensitive, reactive, and acne-prone skin. Its formula is based on 77% heartleaf extract (Houttuynia cordata), a Korean medicinal plant whose anti-inflammatory properties are documented by several in vitro studies. The result: visibly calmer skin within 5 to 10 days, and reduced redness in the long term.
In this guide, you'll find out how to use it effectively, what skin type it's suitable for, which active ingredients it pairs well with, and what truly sets it apart from other soothing toners on the Korean market.

What exactly is heartleaf? 🌿
Heartleaf, or Houttuynia cordata, is a medicinal plant used for centuries in traditional Asian medicine for its anti-infectious and soothing effects. In cosmetics, its interest lies in its ability to inhibit the production of pro-inflammatory cytokines, the molecules responsible for redness and skin reactions.
Concretely, this results in a visible reduction in inflammation, skin that is less reactive to external aggressions, and a gradual decrease in imperfections linked to inflammatory acne. The extract is non-comedogenic, alcohol-free, and fragrance-free, making it usable even on the most irritable skin.
The difference between a 20% heartleaf toner and a 77% toner is a direct concentration-to-efficacy ratio. At high doses, the soothing effect is measurable in a few days. At low doses, the action remains anecdotal.
What skin type is this toner for? 🎯
The Anua Heartleaf 77% Soothing Toner is suitable for most skin types, but three situations particularly highlight its strength.
Acne-prone and combination skin: this is its preferred territory. The aqueous texture does not clog pores, betaine and glycerin moisturize without stimulating sebum production, and the anti-inflammatory action of heartleaf reduces the intensity and frequency of breakouts. After 3 to 4 weeks of regular use, many observe a visible reduction in active pimples.
Sensitive and reactive skin: alcohol-free, fragrance-free, and free of aggressive preservatives, this toner is suitable for skin that poorly tolerates classic formulas. It also works well after dermatological treatments (azelaic acid, retinoids) to calm residual irritation.
Oily skin: the heartleaf concentration indirectly regulates sebum by reducing inflammation often linked to sebum overproduction. The finish is matte, never sticky.
It is less of a priority for dry or mature skin, which would benefit more from a hyaluronic acid or more concentrated centella asiatica toner. For dry skin, it can be integrated as a supplement, not as a primary hydration step.
How to use Anua Heartleaf 77% toner in your routine? ✅
The toner is applied after the cleansing step, on clean and slightly damp skin. The order matters: it prepares the skin to absorb subsequent active ingredients, such as an essence or serum. Here is the complete routine, morning and evening.
- Double cleansing (evening): Korean cleansing oil to dissolve makeup and SPF, then foaming cleanser to deeply purify.
- Gentle cleanser (morning): a quick pass without sulfates is enough to avoid dehydrating the skin.
- Anua Heartleaf 77% Soothing Toner: apply a generous amount with your hands or a cotton pad, gently patting. Do not rub. Allow to absorb for 30 seconds before the next step.
- Essence or serum: follow with a targeted active ingredient depending on the main concern (niacinamide, vitamin C, retinol).
- Moisturizer: seal in the active ingredients with a cream adapted to your skin type.
- Sun protection (morning only): an SPF 50+ is essential to prevent redness from worsening due to UV exposure.
Specialist's tip: apply the toner immediately after rinsing, before the skin dries completely. This is not a constraint: still slightly damp skin absorbs hydrophilic active ingredients better. Waiting for the skin to be completely dry reduces the effectiveness of each subsequent layer.
Does Anua toner help reduce redness? 🔴
Yes, and that is precisely its primary function. Heartleaf (Houttuynia cordata) inhibits the production of pro-inflammatory cytokines, the molecules responsible for persistent redness. In vitro studies have confirmed this action on human keratinocyte cells. On the skin, this translates to a reduction in diffuse redness within 5 to 10 days of regular use.
Panthenol (provitamin B5) present in the formula reinforces this effect by accelerating the repair of the skin barrier. An intact skin barrier reacts less to external irritants, which mechanically reduces episodes of redness. For chronic redness related to rosacea, dermatologist consultation is still recommended before any routine.
Reviews from users with reactive skin confirm a visible reduction in redness after 2 to 3 weeks of morning and evening use, with a more even complexion from the first week.
What active ingredients is it compatible with? ⚗️
The Anua Heartleaf 77% Soothing Toner is one of the few toners that pairs with virtually all common active ingredients. Its neutral formula, free of exfoliating acids and retinol, minimizes the risk of incompatibility.
| Active Ingredient | Compatible? | Usage Tip |
|---|---|---|
| Niacinamide | Yes, no restrictions | Apply toner first, niacinamide serum after |
| Retinol | Yes | Heartleaf reduces retinol-related irritation, especially during the adaptation period |
| Exfoliating acids (AHA/BHA) | With caution | Avoid layering on already irritated skin. On healthy skin, no problem |
| Vitamin C | Yes | Apply toner before vitamin C. The soothing action protects the skin from possible slight irritations |
| Centella asiatica | Yes, enhanced effect | Both active ingredients are synergistic in soothing and barrier repair |
| Hyaluronic acid | Yes | Complementary for hydration. Useful for dry skin needing an extra boost |
If you're starting retinol and your skin is in an adaptation phase, Anua Heartleaf acts as a buffer. It doesn't cancel out the effect of retinol; it simply reduces discomfort during the transition period.

How long until results are visible? ⏱️
Timelines vary depending on the initial state of the skin barrier, but here are the benchmarks observed with regular morning and evening use.
- Week 1: immediate calming sensation after application, reduced post-cleansing redness.
- Week 2: visible reduction in diffuse redness, skin less reactive to temperature variations.
- Week 3 to 4: more even complexion, less frequent imperfections, improved skin texture.
- Month 2 and beyond: strengthened skin barrier, skin generally less sensitive to daily irritants.
These timelines are realistic, not optimistic. If after 4 weeks you don't notice any improvement in intense redness or severe acne, consult a dermatologist. A toner, however concentrated, does not replace appropriate medical treatment.
What's the difference between the 40 ml and 250 ml formats? 📦
The formula is strictly identical in both formats. The difference is purely practical and economic.
The 40 ml format is ideal for trying the product before committing to the larger size, or for travel. With 2 applications per day, it lasts approximately 3 to 4 weeks depending on the generosity of the application.
The 250 ml format is the most commonly used for daily use. It lasts approximately 3 months with one application morning and evening. This is the recommended format once you know the product suits your skin. There is also a 500 ml format for users who have adopted it as their go-to toner.

Is this toner suitable for oily, acne-prone skin? 🔬
This is one of the most common and documented use cases. The toner's aqueous texture does not clog pores. Betaine and glycerin moisturize without overloading the skin or activating compensatory sebum production, that mechanism where dehydrated skin produces even more sebum to compensate.
The anti-inflammatory action of heartleaf tackles acne at its source: inflammation. By reducing pro-inflammatory cytokines, it decreases the size and intensity of active pimples and prevents the appearance of new imperfections. It is not an anti-acne treatment in the medical sense, but it is a solid skin support for mild to moderate acne-prone skin.
For oily skin starting K-Beauty and looking for a complete routine, the guide on COSRX complements this article well: both brands are often combined for acne-prone skin.
