What Does Heartleaf Do for Skin?
Christine Kang
Some skincare ingredients become popular because they’re trending. Others become trusted because they consistently work.
Heartleaf is one of the latter.
Long before it became a recognizable ingredient outside of Korea, heartleaf (Houttuynia cordata) was valued for its ability to support irritated, reactive, and redness-prone skin. Its lasting popularity reflects something we believe strongly at Treats Lab: sensitive skin typically benefits from ingredients that help restore balance, not ingredients that force change.
That perspective shapes how we formulate. Every Treats Lab product is made in Korea and designed specifically for skin that feels easily disrupted—whether by dryness, visible redness, environmental stressors, or eczema-prone flare-ups. Rather than chasing stronger actives or quick-fix solutions, our focus is on barrier support, microbiome health, and long-term skin resilience. It’s also why ingredients like heartleaf continue to play an important role in products such as our ABC Microbiome Calming Lotion and R+R Barrier Recovery Mist.
At Treats Lab, heartleaf is not included as a standalone hero ingredient. It is one of four botanicals that make up our proprietary Bi-Om Complex™, a carefully selected blend designed to support sensitive, reactive, and eczema-prone skin. We chose heartleaf because of its longstanding reputation for promoting skin comfort and visible calm, while also fitting naturally into a broader formulation philosophy centered on balance, barrier support, and microbiome-friendly care

What Is Heartleaf?
Heartleaf, scientifically recognized as Houttuynia cordata, has been embraced in traditional Hanbang Korean medicine and skincare for centuries. This plant is celebrated for its rich concentration of antioxidants and flavonoids, which work harmoniously to soothe irritation and restore skin balance. It’s particularly advantageous for those with sensitive skin, delivering restorative benefits without disrupting skin integrity.
Using heartleaf in skincare reflects a holistic approach that mirrors Korean beauty traditions. It seamlessly integrates into formulations designed to maintain your skin's natural elasticity and hydration, fostering a sense of comfort and resilience.
At Treats Lab, this versatility is one reason heartleaf was selected as part of our Bi-Om Complex™. Rather than relying on a single ingredient to do all the work, we prefer formulation systems where carefully chosen botanicals support one another while contributing to overall skin comfort and balance.
By making heartleaf a part of your skincare routine, you’re empowering your skin to thrive by addressing foundational aspects of skin health—calm, balance, and moisture.

How Does Heartleaf Benefit Sensitive Skin?
Heartleaf shines due to its unique ability to address the common challenges faced by sensitive skin. Known for its calming properties, heartleaf works as an effective anti-inflammatory agent, significantly mitigating redness and irritation. This makes it a soothing ally, especially for skin that reacts negatively to environmental stressors.
When heartleaf penetrates the skin, its antioxidants neutralize harmful free radicals, safeguarding the skin barrier from potential damage. This action is crucial for maintaining optimal hydration levels and enhancing overall comfort. For individuals dealing with conditions like eczema and rosacea, heartleaf can alleviate the discomfort often linked to sensitivity, promoting a more balanced complexion.

At Treats Lab, we formulate specifically for skin that is easily disrupted—whether by dryness, redness, environmental stressors, or eczema-prone flare-ups. This focus has reinforced our belief that sensitive skin responds best to consistent barrier support rather than aggressive treatment cycles.
That philosophy is reflected in our Bi-Om Complex™, where heartleaf was selected alongside other supportive botanicals as part of a broader system designed to help sensitive skin maintain balance over time. Rather than viewing heartleaf as a standalone solution, we see it as one contributor within a carefully constructed formula that prioritizes long-term skin comfort.
You’ll find heartleaf in the ABC Microbiome Calming Lotion, where it helps support hydration and microbiome balance for sensitive skin. Its calming properties complement a barrier-focused approach that prioritizes long-term skin comfort over quick fixes.
What Are the Key Benefits of Heartleaf for Redness?
Individuals with sensitive or reactive skin often battle the persistent issue of redness. Here, heartleaf proves to be invaluable. Its high concentration of bioactive compounds directly targets inflammation, helping to calm irritated areas and promote a more even skin tone. While it might not eliminate redness entirely, consistent use of heartleaf can significantly diminish its visibility.
Regular application of heartleaf supports healing by reinforcing the skin’s barrier function. A stronger barrier is better equipped to fend off irritants and environmental factors that could exacerbate inflammation. For those with rosacea or dermatitis, heartleaf becomes a key part of a soothing skincare arsenal, enhancing both comfort and appearance.
Heartleaf is also featured in the R+R Barrier Recovery Mist, a lightweight mist designed to refresh and comfort stressed skin throughout the day. For skin that feels hot, reactive, or easily irritated, it offers a convenient way to deliver calming support whenever needed.
In both the R+R Barrier Recovery Mist and ABC Microbiome Calming Lotion, heartleaf is used as part of a larger support system rather than as a single active ingredient. This reflects our belief that redness-prone skin often benefits most from multiple complementary ingredients working together to support barrier health, hydration, and overall skin comfort.
Moreover, heartleaf plays an essential role in maintaining adequate moisture levels, which is vital for combating dryness—commonly associated with skin sensitivity. With heartleaf-infused products, you can cultivate a calm and nurturing environment for your skin, allowing it to look and feel its best.

How Does Heartleaf Compare to Centella?
While both heartleaf and centella asiatica are well-regarded for their calming properties, there is often significant overlap in how they are used within skincare formulations. Both are commonly incorporated into products designed for sensitive, reactive, and redness-prone skin because of their reputation for supporting skin comfort and resilience.
Generally speaking, formulators may use heartleaf when focusing on visible calm, comfort, and balance, while centella is frequently highlighted for its association with barrier support and skin recovery. However, these distinctions are not absolute, and many Korean skincare products successfully combine both ingredients because their benefits can complement one another.
When you're addressing overall comfort and hydration, heartleaf shines through. However, if you're dealing with specific areas that need healing—like blemishes or irritated patches—centella may be your go-to. Both ingredients can work synergistically when paired, providing a well-rounded approach to skincare that caters to the needs of sensitive skin.
This complementary philosophy is reflected in products like the ABC Microbiome Calming Lotion and R+R Barrier Recovery Mist, which combine soothing botanicals with barrier-supportive ingredients to help sensitive skin feel more balanced and resilient over time.
By incorporating both heartleaf and centella into your routine, you can enjoy their combined benefits. At Treats Lab, our formulations often embrace the strengths of both, resulting in a skincare regimen that addresses the multifaceted concerns of sensitive skin.

FAQs About Heartleaf
→ What does heartleaf do for the skin?
Heartleaf is a soothing botanical that calms sensitive skin and reduces redness. It’s beloved in the realm of Korean skincare for its ability to restore balance and comfort without aggressive treatments.
At Treats Lab, we value heartleaf not only for its individual properties but also for the role it plays within our Bi-Om Complex™, where it contributes to a broader formulation strategy focused on supporting sensitive, reactive, and eczema-prone skin.
The benefits come from heartleaf’s rich antioxidants, which protect against oxidative stress while soothing irritation. When applied, it helps stabilize the skin barrier, ensuring moisture retention and defense against irritants. This strong barrier is crucial for anyone with sensitive skin, promoting overall health and comfort.
Compared to other calming ingredients like chamomile, heartleaf shines in its ability to support skin barrier integrity rather than merely soothe. Chamomile is great for calmness but doesn’t enhance barrier strength like heartleaf. For those prone to flare-ups, heartleaf might be the more effective option for long-term relief.
To incorporate heartleaf, look for serums or moisturizers emphasizing this ingredient. Applying them after cleansing maximizes their soothing impact. If irritation occurs with initial use, consider patch-testing on a small area to confirm compatibility with your skin.
→ Is heartleaf good for sensitive skin?
Heartleaf is indeed particularly beneficial for sensitive skin, thanks to its calming and restorative attributes. It effectively soothes irritation and diminishes redness without overwhelming the skin, making it perfect for those with reactive skin types. Individual results can vary, but many experience improved comfort over time with heartleaf.
The effectiveness arises from heartleaf's antioxidants and anti-inflammatory compounds, which work to neutralize free radicals and calm your skin's inflammatory responses. This results in reduced irritation from environmental stressors and a more stable skin barrier, pivotal for skincare health.
It’s worth noting that not all soothing ingredients perform equally; for example, while aloe vera also soothes, it may not provide the same level of barrier support as heartleaf. If your skin is highly reactive, heartleaf could be a safer and more effective choice for long-term care.
→ What are the benefits of heartleaf for redness?
Heartleaf excels at reducing redness, making it essential for those with sensitive or reactive skin. Its anti-inflammatory properties help calm irritations, improving overall skin tone. While it may not completely eliminate redness, consistent use can significantly lessen its visibility over time.
The mechanism behind heartleaf's ability lies in its bioactive compounds that target inflammation, assisting your skin's recovery and restoring balance. By soothing irritation and reinforcing the barrier, heartleaf helps ensure better moisture retention while protecting against irritants—critical for conditions like rosacea or dermatitis.
While many ingredients target redness, heartleaf’s strength lies in its soothing qualities. If managing redness is your top priority, heartleaf would likely be the more suitable choice in your regimen.
→ How does heartleaf compare to centella?
Heartleaf and centella are both lauded for their calming properties, yet their benefits often overlap more than they differ. Both ingredients are commonly used in Korean skincare to support sensitive skin, reduce the appearance of irritation, and help maintain a healthy skin barrier.
Rather than viewing them as competing ingredients, many formulators—including Treats Lab—see them as complementary. When used together, they can contribute to a more comprehensive approach to supporting reactive and redness-prone skin.
Heartleaf works through antioxidants and anti-inflammatory compounds that specifically address redness and irritation. Its focus is on strengthening the skin barrier against environmental stressors. Conversely, centella promotes healing of blemishes and scars, making its application ideal for targeted areas. Each ingredient excels in its unique domain but offers potential when used together.
Your specific concern—persistent redness compared to healing—will shape your ingredient preference. Heartleaf is perfect for ongoing redness and sensitivity, while centella may better address recent blemishes. Evaluate your skin’s needs to determine the most fitting choice.
For a comprehensive approach, you may incorporate both heartleaf and centella into your routine. Use heartleaf in the morning for daily comfort while reserving centella for evening applications that concentrate on healing.

→ Are there any side effects of using heartleaf?
Heartleaf is typically well-tolerated across most skin types, particularly for those with sensitive skin. However, as with any skincare ingredient, mild reactions may occur. Being mindful of your skin's individual needs can help mitigate potential side effects.
Potential side effects are often linked to sensitivity toward specific compounds in heartleaf. While its soothing properties are generally beneficial, some individuals may react negatively, particularly if they have a history of sensitivity to botanical ingredients. This highlights the importance of patch testing, allowing you to gauge your skin's reaction before full application.
It’s worth noting that while heartleaf tends to be gentle, other ingredients within a formulation may also provoke reactions. If you have known sensitivities, it’s prudent to scrutinize ingredient labels closely. To minimize potential side effects, gradually introduce heartleaf into your routine, starting with lower concentrations. Monitor your skin's responses closely and adjust usage accordingly.

Whether through the ABC Microbiome Calming Lotion, where heartleaf helps support hydration and microbiome balance, or the R+R Barrier Recovery Mist, which helps comfort stressed skin throughout the day, heartleaf demonstrates why it remains one of Korean skincare’s most trusted ingredients for sensitive skin.
