Cica, Centella, Madecassoside: Untangling Korea's Most Overused Ingredient Story

The word “cica” does not appear on a single centella plant. It is a marketing contraction — short for Cicalfate, the French pharmacy cream from Avène that Korean formulators were quietly studying in the early 2010s. So when an American shopper picks up a green tube at Olive Young labeled “cica,” she is not actually reading a Korean word. She is reading a Korean-language echo of a French brand name, applied to a plant the Vietnamese have been using for wound healing for centuries. Three languages, one leaf, and almost no one at the till could tell you which is which.

This is the cleanest example I know of how K-beauty terminology gets garbled in translation — and why the same green tube can cost four dollars or forty, depending entirely on which molecule inside it is doing the work.

I noticed the confusion most sharply last spring, standing in the Seongsu branch of Olive Young with my friend Hyejin, who has had rosacea-adjacent flushing since her twenties. She picked up the Skin1004 Madagascar Centella ampoule, turned it over, and said — in the slightly dry tone she uses for skincare she is tired of explaining — “Americans think this is the same thing as the Dr. Jart tiger balm. It is really not.” She is right. They share a plant. They do not share a job.

So let’s untangle it. Slowly, and without the wellness-blog breathlessness.

The plant, the extract, the molecule

There are three terms doing work here, and they sit at three different levels of specificity. Getting them in order is the entire game.

Centella asiatica is the plant. A small, scalloped-leaf herb that grows wild across South and Southeast Asia, sometimes called gotu kola, sometimes called pennywort. In Korean it is 병풀 (byeong-pul), literally “wall grass.” This is the raw botanical input. Anything labeled “centella asiatica extract” on an INCI list is a broad-spectrum extraction of the whole plant, which means you are getting a soup of compounds — flavonoids, amino acids, sugars, and a small percentage of the active triterpenes that everyone actually cares about.

Cica is a marketing umbrella. It is not an ingredient. It is not a regulated term. In Europe, where the word originated, “cica” creams typically refer to cicatrisation — the French clinical word for wound healing — and the formulas often contain centella but also zinc, copper, or panthenol. In Korea, “cica” got adopted as shorthand for “the soothing category” around 2017, when Dr. Jart’s Cicapair launched and everything green-tubed followed. So when you see “cica” on a Korean product, you are reading a vibe, not a spec.

Madecassoside, asiaticoside, madecassic acid, and asiatic acid are the four specific triterpenes inside centella that the research literature actually points to. They are sometimes packaged together and abbreviated TECA (Titrated Extract of Centella Asiatica), which is the form most heavily studied in dermatological journals. Madecassoside, in particular, has the most published work on its anti-inflammatory and barrier-repair mechanisms.

This is the hierarchy that matters: plant → extract → isolated active. Each step up costs more to formulate, and each step up does more, measurably, on skin.

Why “centella ampoule” can mean two completely different products

Here is where the Olive Young shelf gets confusing. Two ampoules can both say “centella” on the front, and one can be a humectant toner with a sprinkle of plant water, while the other can be a clinically-meaningful concentration of madecassoside in a stabilized base. Same shelf. Same green. Wildly different intent.

The tell is on the back of the bottle. Flip it over and look for:

• Centella asiatica extract alone, listed mid-formula: this is a soothing-adjacent product. Nice. Not therapeutic.
• Centella asiatica extract listed in the top five, alongside named triterpenes (madecassoside, asiaticoside): now you are looking at something formulated to actually do work.
• Madecassoside listed as a percentage (0.1%, 0.2%, sometimes higher): this is the version a dermatologist would point to if you asked about post-procedure recovery or chronic redness.

The Korean brands that have built their reputations on this category — Skin1004, Purito, Abib, SungBoon Editor, Isntree — generally fall into the second and third buckets. The runaway hit Skin1004 Madagascar Centella Ampoule is essentially a single-ingredient extract done well: 100% centella asiatica extract from Madagascar, where the plant grows in mineral-rich soil that affects its triterpene profile. The Purito Centella Green Level line leans heavier on the isolated madecassoside angle. Knowing which philosophy a brand follows tells you, roughly, what your skin will feel after eight weeks.

Cica is a vibe. Centella is a plant. Madecassoside is a molecule. Pay for the level of specificity your skin actually needs — and not a step higher.

What the research actually supports

I want to be careful here, because the centella story is one of the few in K-beauty where the published evidence is genuinely substantial — and also one of the few where marketing has run several kilometers ahead of what the evidence cleanly supports.

What is well-documented: madecassoside and asiaticoside increase collagen synthesis in fibroblast studies, modulate inflammatory cytokines, and accelerate wound closure in animal models. There is decent human data on TECA for post-laser recovery and for atopic dermatitis support. This is why your Korean dermatologist hands you a centella-based cream after a fractional laser session and not a vitamin C serum.

What is less well-documented but plausible: long-term reduction in visible redness, support for compromised barriers from over-exfoliation, and a calming effect on what Koreans call 민감성 피부 (min-gam-seong pi-bu), sensitive skin.

What is oversold: centella as an anti-aging hero, centella as an acne treatment, centella as a fix for hyperpigmentation. It can be adjacent to all of these — a calmer barrier always helps — but it is not the primary lever.

If your skin is reactive, recently over-treated, or recovering from anything (procedures, accidental retinol overuse, a winter of too-hot showers), centella is one of the most evidence-supported ingredient stories in Korean skincare. If your skin is healthy and your concerns are pigment or fine lines, you are paying for something that will be pleasant but not transformative.

A note on the “tiger grass” thing

You will see “tiger grass” on packaging, especially on products marketed in the U.S. The folk story is that wounded tigers in the jungle rolled in centella to heal. I have never been able to find a primary source for this — it appears in Korean marketing copy around 2015 and propagates from there. Treat it as a charming bit of brand mythology, not an ethnobotanical fact. The plant’s actual traditional use, well-documented in Ayurvedic and Vietnamese medicine, is more interesting than the tiger story anyway: taken internally for circulation and cognition, applied externally for slow-healing skin.

What I keep on my counter

These are products I have actually used through full bottles, at my own expense, with no commission consideration in the picks. I have organized them by the hierarchy above — extract-focused, triterpene-focused, and supporting-cast — so you can match the spec to what your skin actually needs.

✶ Skin1004 Madagascar Centella Ampoule (around $20). A clean, single-ingredient extract. Use this if you want centella in its broadest, gentlest form — a daily layer that calms without doing anything dramatic. The bottle lasts months because you only need a few drops.

✶ Purito Seoul Centella Green Level Buffet Serum (around $22). Layered triterpenes alongside peptides. This is the one I reach for when my barrier has been pushed too hard — after a week of travel, or when I have over-committed to acids.

✶ SungBoon Editor Centella Asiatica Calming Mask (around $30 for five). The post-flight, post-sun, post-everything mask. Twenty minutes of madecassoside-saturated essence in a sheet. Hyejin and I keep these in our refrigerators in Seoul and LA respectively, which I realize sounds precious, but cold sheet masks on inflamed skin are not a debate I am interested in having.

✶ Abib Heartleaf Spot Pad Calming Touch (around $25). Not strictly centella — the lead is Houttuynia cordata, called 어성초 (eo-seong-cho) — but it sits in the same calming-category lineage and is worth knowing about as you build a vocabulary beyond the obvious. Use as a targeted compress on flared areas.

✶ Etude House SoonJung 2x Barrier Intensive Cream (around $18). The unfashionable, unsexy daily moisturizer that does the actual maintenance work between your hero products. Panthenol-led, centella-supported, fragrance-free. The Korean equivalent of Cetaphil with better texture.

The pattern, if you are looking for one: spend on the actives, save on the base layers. A $20 ampoule with real centella does more than a $60 cream with a sprinkling. And no green tube, no matter how prettily designed, can outperform a back-of-label that names its molecules.
