Heartleaf is a popular ingredient in Korean skincare, particularly in toners, cleansers and moisturisers designed around a soothing skincare experience. You may have seen it featured in products for oily skin, blemish-prone complexions or skin that feels easily unsettled.
But what are the benefits of Heartleaf for skin? Does research support the claims made about it, and how do you choose a product that fits your routine?
At The Seoul Palette, we believe good skincare starts with understanding what a product is designed to do, rather than following every new ingredient trend. In this guide, we explore what Heartleaf is, what the research tells us, how it compares with Centella Asiatica, and how to introduce it into a Korean skincare routine.
What Is Heartleaf in Skincare?
Heartleaf is the common name for Houttuynia cordata, a plant native to parts of Asia that has a history of traditional use.
In Korean skincare, Heartleaf-derived ingredients are often included in formulations marketed for soothing and skin comfort. Depending on the product, you may see the plant listed as Houttuynia cordata extract or under another ingredient name that reflects the plant material used.
Heartleaf has attracted scientific interest because researchers have investigated the plant's biological properties, including potential anti-inflammatory and antioxidant activity. However, research on a plant does not automatically prove that a finished cosmetic product will deliver the same effects on human skin.
The formulation, concentration, supporting ingredients and individual skin response all matter.
Why Is Heartleaf Popular in Korean Skincare?
Heartleaf is associated with products designed around skin comfort, and it appears in several types of Korean skincare formulations.
Its popularity does not mean every Heartleaf product will suit every skin type. A cleanser, toner and moisturiser containing Heartleaf can have very different purposes because their complete formulas and directions for use differ.
The useful question is not simply whether a product contains Heartleaf. It is whether the finished product addresses a need in your routine.
What Are the Benefits of Heartleaf for Skin?
Heartleaf is frequently marketed in products intended for skin comfort and routines for oily or blemish-prone complexions. The available evidence needs to be considered carefully, however, because findings about the plant are not the same as proof of benefits from every skincare product containing it.
1. Heartleaf and Skin Comfort
Some Heartleaf products are formulated and marketed for skin that feels uncomfortable or looks temporarily flushed.
Researchers have investigated the anti-inflammatory activity of Houttuynia cordata, but laboratory findings alone cannot establish that every topical Heartleaf product will visibly reduce redness or irritation.
If your skin is easily unsettled, assess the entire ingredient list. Fragrance, other active ingredients and your existing routine may influence whether a particular product feels comfortable on your skin.
2. Heartleaf for Oily Skin
Heartleaf appears in some products marketed towards oily skin. There is also limited clinical research on a specific facial toner containing Houttuynia cordata extract that investigated changes in skin oiliness and moisture.
This is a useful distinction: a finding from one tested formulation does not establish that all Heartleaf products control excess oil. Product formulation, the way it is used and the skin's response all matter.
If excess shine is your main concern, start by choosing a routine that cleanses without leaving your skin feeling stripped and includes moisturiser and sunscreen where appropriate.

3. Heartleaf for Blemish-Prone Skin
Heartleaf is often featured in products marketed for blemish-prone skin. However, it should not be treated as a proven standalone acne treatment or a replacement for appropriate acne care.
If you experience persistent breakouts, consider the role of each product in your routine rather than expecting one botanical ingredient to address every concern.
Our guide to Korean Skincare for Acne-Prone Skin in South Africa explains how to approach a routine without adding unnecessary steps.
4. Heartleaf and Hydration
A Heartleaf product may also contain humectants or moisturising ingredients that help support skin hydration. Any hydration benefit depends on the complete formulation, not simply the presence of Heartleaf.
If your skin feels tight or dehydrated, consider whether your routine includes a suitable moisturiser. Adding several new products is not necessarily more effective than choosing one product that serves a clear purpose.

What Does the Research Say About Heartleaf?
Research into Houttuynia cordata has explored several biological properties, but the strength of the evidence varies according to the study and the outcome being measured.
Laboratory research can help scientists investigate how a plant or its compounds behave under particular conditions. It cannot, on its own, establish how well a cosmetic product works on human skin.
What Has a Human Study Found?
A 2023 study published in the journal Cosmetics investigated a facial toner containing Houttuynia cordata extract.
The study compared the developed toner with a toner without the extract. It reported differences in measured skin oiliness and moisture over eight weeks.
The findings are relevant because they involve a specific topical formulation and measurements on human skin. However, the study was small, involving 16 volunteers divided between the test and comparison formulations. It does not prove that every Heartleaf toner, serum or moisturiser will produce the same results.

What does this mean when choosing skincare?
Heartleaf is an ingredient with research worth exploring, but broad claims should be treated cautiously. Evidence for one formulation cannot automatically be applied to every product featuring the same botanical ingredient.
Look at the finished formula, the purpose of the product and the evidence supporting the specific claims being made.
Heartleaf vs Centella Asiatica: Which Should You Choose?
Heartleaf and Centella Asiatica are different botanical ingredients used in Korean skincare. Both appear in products marketed for soothing and skin comfort, but they should not be treated as interchangeable.
| Comparison | Heartleaf | Centella Asiatica |
|---|---|---|
| Botanical name | Houttuynia cordata | Centella asiatica |
| Common skincare positioning | Often featured in soothing-focused products and products marketed for oily or blemish-prone skin | Often featured in soothing and skin-comfort formulations |
| Research considerations | Findings from plant research do not automatically prove benefits from finished cosmetic products | Evidence depends on the particular Centella preparation and the outcome studied |
| Choosing a product | Consider the complete formula, texture and your skin's tolerance | Consider the complete formula, texture and your skin's tolerance |
Neither ingredient is automatically the better choice for everyone. The right option depends on your priorities, the finished product and how your skin responds.

How to Choose a Heartleaf Skincare Product
You do not need an entire Heartleaf routine to explore this ingredient. Start by identifying the step your existing routine is missing.
Choose the Right Product Format
Cleanser: Choose a cleanser that removes daily residue without leaving your skin feeling uncomfortably tight. Follow the product's directions and avoid over-cleansing.
Toner or serum: A leave-on product may suit someone who wants to add a lightweight step after cleansing. Consider the complete ingredient list and whether the product complements your current routine.
Moisturiser: If you need a moisturising step, a Heartleaf moisturiser may be worth considering. Choose a texture that feels comfortable rather than assuming that every skin type needs the same consistency.
Mist: A facial mist may appeal if you prefer a spray format. A mist is not automatically a substitute for moisturiser, so consider its formulation and intended use.
Look Beyond the Featured Ingredient
Product marketing often highlights a headline ingredient, but Heartleaf alone does not tell you everything about how a product may perform.
Before choosing a product, consider:
- The complete ingredient list and any ingredients you know your skin does not tolerate well.
- Whether the product is rinse-off or leave-on.
- Its intended purpose and directions for use.
- Whether you already have a product that performs the same role.
- How it fits into your current routine.
If your skin is reactive, introduce new products gradually and follow our Korean Skincare Patch Testing Guide.
Stop using a product if it causes a concerning reaction. An ingredient marketed for soothing is not guaranteed to suit everyone.
How to Use Heartleaf in a Korean Skincare Routine
The simplest approach is to start with one Heartleaf product and keep the rest of your routine familiar. You do not need to change every step at once.
Morning Routine
- Cleanse gently, if needed.
- Apply your Heartleaf toner or serum, if you have chosen one.
- Apply moisturiser if your skin needs it.
- Finish with a broad-spectrum sunscreen of at least SPF 30.
Evening Routine
- Cleanse to remove sunscreen, makeup and daily residue.
- Apply your Heartleaf leave-on product, if using one.
- Apply moisturiser.
Follow the instructions for your specific product and introduce it gradually. If you already use treatment products, consider their directions and your skin's tolerance before adding another step.
The aim is to build a routine that works for your skin, not to include an ingredient simply because it is popular.
Can You Use Heartleaf With Other Skincare Ingredients?
Heartleaf may fit into a routine containing other skincare ingredients. Compatibility depends on the individual products, how they are used and your skin's tolerance.
Heartleaf and Hyaluronic Acid
Hyaluronic acid is a humectant commonly used in skincare to support hydration. A Heartleaf product and a hyaluronic acid product may be used in the same routine if both suit your skin.
You may not need separate products containing both ingredients if your existing moisturiser or serum already meets your needs.
Heartleaf and Niacinamide
Niacinamide is used in skincare for several purposes, including supporting the skin barrier and improving the appearance of uneven skin tone.
Whether you need both Heartleaf and niacinamide depends on your skincare priorities and the products you already use. Check the complete formulas rather than judging products by their headline ingredients alone.
Heartleaf and Acne Treatments
If you use an acne treatment, follow its directions and introduce additional products cautiously. Heartleaf should not be assumed to prevent irritation from another active ingredient or replace appropriate acne treatment.
If your routine is already working well, there may be no need to add another product.
Is Heartleaf Worth Exploring?
Heartleaf is an interesting botanical ingredient in Korean skincare, particularly if you are exploring products marketed around skin comfort. Research into Houttuynia cordata includes promising areas of investigation, but evidence from a specific study should not be generalised to every Heartleaf product.
The most useful approach is to choose a product based on its complete formulation, intended purpose and suitability for your routine.

Choose thoughtfully, introduce new products gradually and build your skincare routine around your needs rather than the latest ingredient trend.
