Heartleaf
Heartleaf became a K-beauty household name almost entirely because of one brand — Anua built its reputation on heartleaf toners and cleansers — but the ingredient itself is a genuinely useful calming plant extract worth understanding on its own. Here's what it does, who it suits, how it differs from centella, and where it works best.
Heartleaf, also called houttuynia cordata, is a plant extract used in Korean skincare to calm redness, reduce excess oil, and support a compromised skin barrier. It's become closely associated with Anua's toner and cleanser line, but the ingredient itself is a broader calming extract that shows up across cleansers, toners and pads from multiple brands, valued for settling irritated or oily-but-sensitive skin without adding heaviness.
Benefits
Heartleaf's reputation rests on antibacterial and anti-inflammatory properties documented in traditional use, and modern formulations lean on those same properties to calm redness, reduce the appearance of irritation, and help regulate excess sebum. It's an unusual combination — most calming ingredients don't also help with oil control — which is part of why it built a following among people whose skin is both reactive and oily.
It suits oily or combination skin that flushes easily or breaks out in response to typical oil-control products, skin recovering from a breakout or an aggressive cleanser that's left it stripped, and anyone looking for a lighter-weight calming ingredient than a rich centella cream would provide. It tends to show up most often in toners, essences and cleansers rather than heavier treatments.
It isn't only a face ingredient. The same antibacterial and anti-inflammatory profile that settles reactive facial skin works on an itchy or flaking scalp, which is why heartleaf turns up in shampoos and scalp treatments as well as toners. If your scalp is the part of you that reacts, the ingredient is just as relevant there — and a scalp product is often the easier place to start with it.
What it won't do is resurface texture, fade dark spots, or deliver dramatic before-and-after transformations. Its job is calming and balancing, not correcting. Dry skin without an oil-control need may find it thinner than a richer routine requires.
Recommended
- Genuine heartleaf
All-in-One Vegan Shampoo Ball - Heartleaf Green
ERIGERON$255.0 (1)
A hair-care bar rather than a facial product, and the heartleaf here is real — houttuynia cordata extract is named directly on the ingredient list, not implied by the product name. The heartleaf green formula calms an itchy or irritated scalp, which is the same anti-inflammatory job the ingredient does on the face, applied where a lot of people actually need it. A solid pick for scalp sensitivity or dandruff-adjacent irritation.
AC Clear Pure Cica Toner
The Plant Base$224.5 (104)
Not heartleaf — this one is centella — but it's a genuine calming toner doing the same job for facial skin, built on a high concentration of centella asiatica leaf water. Centella and heartleaf calm redness through different plant compounds, so the effect is comparable even though the ingredient isn't. The watery texture and cooling agent make it the one to reach for on a flushed day.
AC Clear Cica Cleansing Foam
The Plant Base$19.74.2 (97)
Also centella rather than heartleaf, and the natural partner to the toner above — a gentle, non-stripping wash for skin that reacts to a standard foaming cleanser. Centella asiatica leaf extract is named directly on the list. Mild AHA, BHA, PHA and LHA acids sit alongside it, so it does light exfoliation as well as soothing, which suits congestion-prone skin.
How to use
Heartleaf toners and essences go on right after cleansing, while skin is still slightly damp, so the calming effect reaches skin before anything heavier is layered on top.
If you're using a heartleaf cleanser, that's typically step one of a double cleanse or a standalone wash on lighter makeup days, followed by a toner if you want to double up on the ingredient. That's fine — heartleaf doesn't carry the irritation risk that makes layering a problem with actives.
Daily use, morning and night, is standard, with no cycling or tolerance period required.
If oily skin is your main concern, pat rather than rub the toner in, and let it absorb before a lightweight moisturizer. Oily skin still needs a moisture layer to stay balanced.

Questions
What is heartleaf and why is it associated with Anua?
Heartleaf is houttuynia cordata, a plant extract used for its calming and antibacterial properties. Anua built much of its early reputation on heartleaf-based toners and cleansers, which is why the ingredient and the brand are so closely linked in most people's minds.
Is heartleaf good for oily skin?
Yes — it's one of the few calming ingredients that also supports oil regulation, which makes it a common pick for oily or combination skin that reacts poorly to typical mattifying products.
How is heartleaf different from centella (cica)?
Both calm irritation, but heartleaf tends to show up in lighter formats like toners and cleansers with an added oil-balancing effect, while centella is more often found in richer creams and serums focused purely on barrier repair. For pure calming, they're broadly interchangeable.
Does heartleaf work on the scalp as well as the face?
Yes, and it's underrated there. The antibacterial and anti-inflammatory properties that settle reactive facial skin do the same on an itchy or flaking scalp, which is why the ingredient appears in shampoos and scalp treatments as well as toners.
Can heartleaf help with acne?
It can support skin dealing with breakout-related redness and irritation through its calming and mild antibacterial action, but it isn't a treatment for active acne itself — pair it with an actual acne-targeting active rather than relying on it alone.
Is heartleaf safe to use every day?
Yes, it's gentle enough for daily use in both morning and evening routines without the cycling or gradual introduction that stronger actives require.
