The Trend Graveyard Centella and Heartleaf Somehow Avoided
Look back at Korean skincare over the past several years and you'll find a long list of ingredients that had their moment and quietly disappeared. Snail mucin surged and settled into a smaller niche. Certain fermented waters and viral toners came and went within a single season. New regenerative actives are already crowding this year's headlines.
Centella asiatica and heartleaf never had that arc. Both have been fixtures in Korean calming skincare for years now, showing up in everything from a first cleanser to a rescue cream, and neither has been displaced by whatever ingredient happened to be trending that particular month. That kind of staying power in an industry built on constant novelty is worth taking seriously as its own kind of evidence.
Ingredients don't survive that long in a fast-moving market by accident or nostalgia. They survive because they keep doing the job people bought them for, repeatedly, across a huge range of skin types and concerns, which is a harder thing to fake than a single viral launch.

What Centella Is Actually Doing on Your Skin
Centella asiatica, commonly shortened to cica, gets its effect from four key bioactive compounds: asiaticoside, madecassoside, asiatic acid, and madecassic acid. Together they support skin's barrier function, calm visible irritation, and, less commonly discussed, actively stimulate collagen production at the same time.
That dual action is unusual for a calming ingredient. Most soothing actives either reduce inflammation or support structural repair, rarely both at once. Centella does both, which explains why it shows up equally in redness-focused rescue creams and in more structural anti-aging formulas without feeling out of place in either category.
Asiaticoside is the compound most closely tied to that collagen-supporting effect, while madecassoside and madecassic acid handle more of the anti-inflammatory work, calming the visible signs of a stressed or reactive complexion. Asiatic acid rounds things out by supporting the lipid production responsible for a stronger, more resilient skin barrier.
Why Heartleaf Plays a Different Role
Heartleaf, or Houttuynia cordata, known in Korea as eoseongcho, comes from a completely different plant family than centella and does a genuinely different job, even though the two frequently get lumped together as interchangeable calming ingredients. Heartleaf's strength lies specifically in its antibacterial and anti-inflammatory properties, which makes it particularly effective for acne-related redness and irritation in a way centella's broader calming action doesn't specifically target.
Where centella works across a wide range of concerns without much specialization, heartleaf leans hard into addressing the bacterial and inflammatory side of breakouts. It's rich in flavonoids and polyphenols that help calm active blemishes while also offering some antioxidant protection against the kind of environmental stress that accelerates visible aging.
This distinction is the reason serious formulators rarely treat centella and heartleaf as fully interchangeable. A cream built for general barrier support and everyday calming leans toward centella. A toner or spot treatment built specifically for acne-prone, reactive skin leans toward heartleaf, and the more sophisticated formulas increasingly combine both to cover a wider range of what stressed skin actually needs.
Why Neither Ingredient Got Replaced
Part of the reason centella and heartleaf have avoided the usual trend cycle comes down to how broadly tolerable both ingredients are. Neither one exfoliates, neither disrupts skin's pH, and neither requires the careful introduction and patch-testing that stronger actives like retinoids or acids demand. That low barrier to entry means almost anyone can use either ingredient without much risk, which keeps demand steady across an enormous range of skin types and concerns.
The other part is simply that both ingredients have accumulated a genuinely deep research base over time. Centella has documented use in wound healing and traditional medicine going back thousands of years, and modern pharmaceutical-grade extracts have been used in Europe for chronic wound and scar treatment since the 1970s. Heartleaf carries a similarly long history in East Asian traditional medicine, which gave both ingredients a research and cultural head start that newer trend ingredients simply haven't had time to build.
Every few months, a new regenerative or novel ingredient tries to claim the calming and repair space that centella and heartleaf have occupied for years. Most of those newer entries eventually settle into a smaller supporting role rather than displacing either staple, precisely because the newer options haven't yet accumulated anywhere near the same volume of consistent, real-world evidence.

How to Use Both Without Overcomplicating a Routine
Centella and heartleaf both layer easily almost anywhere in a routine, which is part of their appeal. A centella-based toner or essence works well right after cleansing, and a heavier centella cream can anchor the final moisturizing step, especially on nights when skin needs extra barrier support after using a stronger active elsewhere in the routine.
Heartleaf shows up just as flexibly, whether as a toner to rebalance skin immediately after cleansing, a spot treatment for an active breakout, or a lightweight essence layered under other products. Its watery, fast-absorbing texture makes it easy to add without disrupting the rest of a routine's layering order.
Combining both isn't redundant, since they're covering slightly different ground. A heartleaf toner followed by a centella serum or cream gives skin both the bacterial-calming benefit and the broader barrier and collagen support in the same routine, which is increasingly how more advanced Korean formulas are built rather than choosing one ingredient over the other.
The Concentration Problem Worth Knowing About
Both ingredients share the same formulation trap that affects almost every popular skincare active eventually. A product can legally list centella asiatica extract or Houttuynia cordata extract on its ingredient panel while containing such a small amount that it does essentially nothing meaningful for skin. The word cica in particular has become common enough in marketing that it's sometimes attached to products with only trace amounts of the actual ingredient behind it.
Checking where the ingredient sits on the full list, rather than trusting front-of-package claims, remains the most reliable way to judge whether a formula is using a meaningful concentration. Products built specifically around centella or heartleaf as the hero ingredient, rather than one item in a long supporting cast, tend to be more reliable choices for anyone specifically trying to treat redness, irritation, or acne-related inflammation.

Who Gets the Most Out of Each Ingredient
Anyone dealing with a compromised or reactive barrier, whether from over-exfoliation, weather changes, or a new active that didn't agree with their skin, tends to see the fastest, most noticeable benefit from centella. Its combination of barrier support and gentle collagen stimulation makes it a reasonable default for almost any kind of stressed skin, which is part of why it's become the go-to recommendation for post-procedure recovery and general sensitivity alike.
Heartleaf earns its place more specifically with acne-prone and oily-combination skin, where its antibacterial action addresses the inflammatory side of breakouts more directly than centella's broader calming effect. Anyone managing frequent blemishes alongside redness and irritation often finds heartleaf products noticeably more targeted for that specific combination of concerns.
Skin that's simultaneously dealing with both breakouts and general reactivity, a combination more common than either issue occurring cleanly on its own, tends to benefit most from using both ingredients together rather than picking one and hoping it covers everything. That layered approach, rather than treating the two as competing options, reflects how most experienced Korean skincare routines actually use them in practice.
A Reasonable Expectation for Sensitive Skin
Both centella and heartleaf carry a strong safety profile, and serious reactions to either are rare even among people who react poorly to most active ingredients. That said, plant-derived extracts still vary in purity and extraction quality between brands, and even a generally gentle ingredient can occasionally cause irritation in someone with a specific botanical sensitivity.
A patch test remains a reasonable habit when trying either ingredient for the first time, even though the odds of a negative reaction are meaningfully lower here than with most other actives covered in skincare content right now. That gentle, broadly tolerable profile is, in the end, one more reason both ingredients have held their place for as long as they have, and it's a large part of why dermatologists reach for them first when recommending a starting point for someone rebuilding a routine from scratch.
Why This Kind of Staying Power Actually Matters
The newest regenerative ingredient making headlines this month will eventually face the same test centella and heartleaf have already passed repeatedly: does it keep performing once the initial hype fades, across a genuinely wide range of skin types, over years rather than a single viral season. Most trend ingredients quietly settle into a smaller niche once that test runs its course.
Centella and heartleaf passing that test isn't a coincidence or a marketing accident. It's the clearest sign available that an ingredient earns its place in a routine, and it's exactly why both remain worth keeping in a skincare shelf regardless of whatever new name shows up in next month's headlines.
