If you've browsed a skincare shelf in the last two years, you've seen the word "cica" on approximately everything. Moisturisers. Serums. Face mists. Sheet masks. It's on packaging in green letters, usually next to a drawing of a small leaf, positioned as the answer to whatever your skin is currently complaining about.
But what is centella asiatica actually doing to your skin? Is it genuinely worth the hype, or is it another ingredient that sounds impressive and does nothing? Let's be honest about it.
What Centella Asiatica Actually Is
Centella asiatica is a small, creeping plant that grows in tropical wetlands across Asia, Africa, and parts of the Pacific. It's been used in traditional medicine for thousands of years — in Ayurvedic practice, in Chinese medicine, and across Southeast Asia — primarily for wound healing and skin repair.
In skincare, it goes by several names: centella, cica (short for cicatrisant, meaning "wound-healing"), gotu kola, tiger grass (because tigers reportedly rolled in it to heal their wounds — nobody has verified this with the tigers), and sometimes just "that green ingredient in Korean skincare."
They're all the same plant. The name changes depending on who's marketing it.
What the Science Says
Here's where centella separates itself from most trending ingredients: it has genuine, peer-reviewed research behind it. Not one study. Decades of studies.
The active compounds are called triterpenoids — specifically asiaticoside, madecassoside, asiatic acid, and madecassic acid. These four compounds are responsible for most of centella's proven effects:
Skin barrier repair. Centella stimulates the production of collagen types I and III — the structural proteins that keep your skin firm and resilient. When your skin barrier is compromised (from over-exfoliation, harsh weather, pollution, or just existing in a modern city), centella helps rebuild it. This isn't marketing language — multiple clinical studies have confirmed increased collagen synthesis with topical centella application.
Anti-inflammatory. Madecassoside in particular has been shown to reduce skin inflammation by inhibiting specific inflammatory pathways. In practical terms: redness calms down, irritation settles, and reactive skin becomes less reactive over time. This is why dermatologists recommend centella products for people with rosacea, eczema, and post-procedure skin.
Wound healing. This is centella's oldest and most documented use. The triterpenoids accelerate the skin's natural repair process — not by masking damage but by genuinely speeding up cellular regeneration. It's why centella is increasingly found in products designed for use after chemical peels, laser treatments, and microneedling.
Antioxidant protection. Free radicals from UV exposure and pollution break down collagen and accelerate ageing. Centella's antioxidant properties help neutralise these free radicals before they can do damage. It's not a replacement for sunscreen — nothing is — but it's a meaningful second line of defence.
Why Madagascar Centella Specifically
Not all centella is created equal. The concentration of active triterpenoids varies dramatically depending on where the plant is grown — soil composition, altitude, climate, and sunlight all affect potency.
Madagascar centella is widely regarded as the most potent. The island's unique combination of rich volcanic soil, tropical humidity, and specific growing conditions produces centella with higher concentrations of the four key triterpenoids than plants grown elsewhere. It's the same reason that wine from certain regions tastes different — terroir matters for plants too.
This is why brands like SKIN1004 source exclusively from Madagascar and built their entire product range around it. Their Madagascar Centella Hyalu-Cica Cloudy Mist uses centella sourced directly from the island, combined with three types of hyaluronic acid and 40% green tea water. It's one of the most popular centella face mists in K-beauty — and the sourcing is a significant reason why.
Centella vs Niacinamide vs Hyaluronic Acid
If you're wondering how centella compares to the other ingredients you see everywhere:
Hyaluronic acid hydrates by drawing water into the skin. That's essentially all it does — and it does it well. But it doesn't repair, protect, or strengthen.
Niacinamide (vitamin B3) is a multitasker — it strengthens the skin barrier, controls oil, reduces redness, and brightens. It overlaps with some of centella's benefits but works through different mechanisms.
Centella repairs, soothes, and protects. It's the ingredient that actively rebuilds damaged skin rather than just hydrating or brightening it.
The best products combine all three. The SKIN1004 Cloudy Mist, for example, pairs centella with three types of hyaluronic acid. The Summer Fridays Jet Lag range combines centella with niacinamide and ceramides. When these ingredients work together, each one amplifies the others.
How to Use Centella in Your Routine
Centella works at almost any step in a skincare routine, which is part of why it appears in so many different product types:
As a face mist — the most versatile option. Spray after cleansing as a hydrating prep layer, over makeup to refresh, mid-flight to combat dry cabin air, or at your desk for an afternoon pick-me-up. A centella face mist is the easiest way to add cica to your routine without changing anything else.
In a serum — concentrated centella serums deliver the highest dose of active triterpenoids. Apply after cleansing and toning, before moisturiser.
In a moisturiser or mask — centella in leave-on products has the most time to work. The longer it sits on skin, the more the active compounds can absorb.
In a cleanser — the gentlest introduction. Centella in a cleanser soothes during the cleansing process, though contact time is shorter than leave-on products.
Centella plays well with virtually every other ingredient — retinol, vitamin C, AHAs, BHAs, peptides. It's one of the rare actives that doesn't conflict with anything. If anything, its soothing properties make it an ideal partner for harsher actives like retinol that can cause irritation.
Who Should Use It
Honestly? Almost everyone. But centella is especially valuable for:
Sensitive or reactive skin — the anti-inflammatory properties calm redness and irritation without adding more actives that might trigger a reaction.
Post-treatment skin — after peels, laser, microneedling, or any procedure that compromises the skin barrier.
Travellers — flying, climate changes, and disrupted routines all stress the skin. Centella helps it cope. This is why it features prominently in our Travel Gifts for Mum collection — alongside other travel essentials like silk sleep masks and jet lag skincare.
Anyone concerned about ageing — the collagen-stimulating and antioxidant properties make centella a meaningful anti-ageing ingredient, especially when used consistently.
People who've over-exfoliated — we've all been there. Too much retinol, too many acids, skin that's red and angry. Centella helps rebuild what you've stripped away.
The Bottom Line
Centella asiatica isn't a trend. It's a genuinely effective skincare ingredient with decades of clinical evidence behind it. The K-beauty world didn't invent it — they just recognised what traditional medicine has known for centuries and put it into formulations that deliver the active compounds effectively.
Is every centella product worth buying? No. Look for products that use centella at meaningful concentrations (not buried at the bottom of the ingredient list), ideally sourced from Madagascar, and combined with complementary ingredients like hyaluronic acid and niacinamide.
The SKIN1004 Madagascar Centella Hyalu-Cica Cloudy Mist ticks every box — high-concentration Madagascar centella, three types of hyaluronic acid, 40% green tea water, and a delivery format (ultra-fine mist) that makes it the easiest possible addition to any routine. It's a good place to start.
