Cica has gone from an obscure herbal extract to one of the most common ingredients in moisturizers, serums, and creams. You’ll find it in everything from luxury formulations to drugstore gels promising to calm, heal, and strengthen your skin barrier.
Behind the buzzword is Centella asiatica , a modest wetland herb that’s been used in Asian traditional medicine for centuries. Today, dermatologists and cosmetic chemists are exploring its compounds for measurable, skin-repairing results.
Here’s a practical, evidence-based breakdown of what cica actually is, how it works, where the hype makes sense, and how to use it wisely.
Key Points
- Cica refers to Centella asiatica, a herb with anti-inflammatory and collagen-boosting properties now common in skincare.
- It supports wound healing, strengthens the skin barrier, and calms irritation, especially for sensitive skin.
- Clinical studies confirm benefits for redness, hydration, and barrier recovery, with best results from leave-on products.
- Safe for most users, though concentrations and product formulations vary; patch testing is advised for sensitive skin.
What Exactly Is Cica?
“Cica” is the beauty shorthand for Centella asiatica , also called gotu kola or Indian pennywort. It’s a creeping herb native to parts of Asia, long prized in Ayurveda and traditional Chinese medicine for healing wounds and calming inflammation.
In skincare, cica typically appears on labels as:
- Centella Asiatica Extract , Leaf Extract , or Water
- TECA (Titrated Extract of Centella Asiatica) – a standardized blend often used in European topical drugs
- The “Centella Four” triterpenes :
- Madecassoside
- Asiaticoside
- Madecassic acid
- Asiatic acid
Each of these compounds contributes anti-inflammatory, antioxidant, and wound-healing activity. Research links them to improved collagen formation, reduced redness, and stronger skin barrier function.
Clinical reviews describe several pathways influenced by Centella actives, including TGF-β/Smad , NF-κB , Wnt/β-catenin , MAPK , and STAT . These mechanisms help explain why the ingredient supports collagen synthesis and reduces inflammatory reactions in skin.
Why You Are Seeing Cica Everywhere Right Now
Two major forces brought cica into global skincare:
1. The K-Beauty Effect
Korean brands made skin barrier care the new foundation of skincare. Instead of chasing harsh actives, they emphasized moisture balance and soothing.
Cica fits perfectly. It started as a hero ingredient in “repair creams” designed to calm post-procedure skin and became a star in nearly every “sensitive skin” line by the mid-2020s.
2. Dermatology Meets Cosmetics
Regulatory and clinical literature already recognized Centella asiatica for supporting wound healing and barrier repair.
That overlap between medicinal and cosmetic benefits made it appealing to dermatologists and formulators. It also complements modern actives like retinoids and acids that can irritate skin.
What the Science Says
Researchers have spent decades studying Centella asiatica, and the evidence behind its skin effects is now easier to grasp. Here’s what current data actually shows about how cica calms, heals, and strengthens the skin barrier.
1. Calming Irritation and Redness
A 2025 clinical study involving 100 adults with sensitive skin found that a Centella-containing cream improved redness, discomfort, and skin barrier function over four weeks. Participants also showed better sebum balance and pH regulation.
A 2024 controlled trial reported that a Centella repairing mask, used alongside standard rosacea therapy, enhanced barrier integrity in mild to moderate cases.
What That Means for You
If your face flushes easily or stings from retinoids, exfoliants, or cold weather, cica creams can provide gentle relief.
Look for Centella extract or madecassoside in the first half of the ingredient list for effective concentrations.
2. Wound Healing and Scar Care

Studies show that Centella triterpenes promote fibroblast activity, collagen synthesis, and new cell growth. They also regulate inflammation through TGF-β signaling and other cascades.
Clinical Context
Controlled studies found that Centella-based creams helped prevent hypertrophic scars and supported wound closure in burns and ulcers. European medicinal products historically contained 1 percent TECA for ulcers and burns.
What That Means for You
Cica won’t erase scars overnight, but it can be a supportive part of a healing routine when combined with SPF and medical advice. For surgical or serious wounds, always follow a clinician’s protocol.
3. Barrier Function and Hydration
Human trials show that Centella-based formulations reduce transepidermal water loss and improve hydration. They also seem to increase tolerance for active ingredients by reinforcing the skin’s outer layers.
Its antioxidant activity helps neutralize free radicals generated by pollution or UV exposure, protecting lipids and proteins in the barrier.
What That Means for You
If your skin feels tight after cleansing or cold weather, a cica moisturizer can smooth out that discomfort and enhance overall resilience.
4. Acne, Eczema, and Photoaging
Early evidence points toward mild benefits for acne and eczema through reduced inflammation and faster healing. However, most studies are small or preclinical, so more human data is needed.
As for anti-aging, Centella’s collagen-boosting potential shows promise in texture and firmness studies, but the strongest data still centers on soothing and barrier repair.
How Cica Works Inside the Skin
The main Centella actives: madecassoside, asiaticoside, asiatic acid, and madecassic acid, act on multiple cellular processes:
| Pathway / Effect | What It Does |
| NF-κB and cytokines | Reduces inflammation signals |
| TGF-β and collagen I/III expression | Promotes tissue repair and firmness |
| Keratinocyte migration | Helps surface cell renewal and wound closure |
| Antioxidant defense | Neutralizes free radicals that degrade skin lipids |
The overall result is calmer, more hydrated skin that recovers faster from irritation.
Safety, Concentration, and Real-World Tolerability
Cica is generally well tolerated, but knowing how much is used and how it behaves on real skin helps separate safe use from overhype.
Cosmetic Safety Consensus
The Expert Panel for Cosmetic Ingredient Safety reviewed nine Centella-derived ingredients and found them safe as used in cosmetics, provided manufacturing quality is controlled.
Typical Use Levels
- Centella extract: up to 0.5 percent in most face products
- TECA (1 percent): used historically in medicinal ointments for ulcers and burns
- Cosmetic blends: often combine multiple fractions at lower levels
Allergy and Sensitivity
True allergic contact dermatitis is rare but documented, including new patch-test cases in 2024 . If you react easily, test products on the jawline before full use.
Pregnancy and Breastfeeding
Topical use at cosmetic concentrations appears low-risk, though data remain limited. Avoid high-dose Centella supplements unless advised by your doctor.

Where Cica Helps Most
Cica shines when your skin feels stressed, tight, or easily irritated. Here’s where it delivers the most noticeable relief.
1. Skin That Flushes or Stings Easily
Choose a fragrance-free cica moisturizer or serum as your everyday calming layer. Use it consistently for at least a few weeks to strengthen your skin’s tolerance. If using retinoids, layer cica afterward or mix a small amount as a buffer.
2. Starting a Retinoid or Acid Routine
Pair cica with ceramides . Centella aids surface recovery, while ceramides fill the lipid gaps that retinoids can thin out. Use cica on off-nights or as a “sandwich” layer before and after actives.
3. Wind, Cold, or Harsh Cleansers
Opt for a rich cica balm or cream with glycerin, squalane, or petrolatum. Studies show barrier recovery after 2 to 4 weeks of use.
4. Healing from a Minor Procedure or Scrape
With medical approval, you can apply cica to support recovery and minimize scarring. Stick to gentle, fragrance-free options and always include SPF. Do not apply to open or infected wounds.
How to Shop Smart
1. Choose Leave-On Products
Rinse-off cleansers won’t allow enough contact time. Most benefits come from creams, balms, or serums left on the skin.
2. Keep It Simple
Many “cica creams” also include fragrance or essential oils that can cause irritation. For reactive skin, look for minimalist formulas.
3. Pair With Complementary Actives
- Niacinamide: enhances barrier repair
- Ceramides & Cholesterol: replenish natural lipids
- Panthenol & Glycerin: attract moisture
- Azelaic Acid: helps redness-prone skin
4. Don’t Over-Layer
More soothing products don’t always mean better results. Build a short, consistent routine.
5. Be Realistic
Cica helps comfort and maintain balance but won’t treat cystic acne, eczema flares, or deep wrinkles alone.
Practical Routines You Can Copy
Here are a few simple, dermatologist-inspired routines that show how to work cica into your daily skincare without overcomplicating things.
Barrier Reset Routine
AM:
- Gentle, non-foaming cleanser
- Cica moisturizer
- Mineral sunscreen
PM:
- Cleanser
- Cica serum or cream
- Optional petrolatum seal on dry areas
Retinoid Sandwich Routine
- Apply pea-sized retinoid on dry skin
- Wait 10 minutes
- Finish with a thin cica cream layer
Post-Acid Night Routine
- Use AHA or BHA exfoliant
- Wait 10–15 minutes
- Apply cica balm to calm the skin
Who Should Be Careful
| Group | What to Keep in Mind |
| Ultra-sensitive or allergic skin | Patch test for 3 nights. Some people develop contact dermatitis from Centella itself or fragrance in formulas. |
| Pregnant or breastfeeding | Topical use seems safe; avoid supplements unless prescribed. |
| Open wounds or infections | Only use Centella products cleared by your clinician; medicinal ointments differ from cosmetics. |
Quick Myth Check
| Myth | Reality |
| “Cica can replace sunscreen.” | False. It helps soothe, not protect from UV. You still need SPF. |
| “All cica creams are identical.” | False. Extraction and concentration vary widely. |
| “If one cica product stings, all will.” | Not true. The irritation could come from added fragrance or acids. Try a simpler formula. |
Reference Table
| Use Case | Best Format | Pair With | Notes |
| Red, easily irritated skin | Leave-on cream or serum | Niacinamide, ceramides | Studies show visible improvement after 2–4 weeks. |
| Rosacea support | Sheet mask or leave-on cream | Prescription topicals | Controlled trials show barrier gains as adjunct therapy. |
| Scar prevention | Cream or gel under medical advice | Silicone sheeting, SPF | Human trials indicate reduced hypertrophic scarring. |
| Post-procedure calming | Balm or ointment if approved | Sunscreen | TECA 1 percent used in European medicinal ointments. |
Bottom Line
Cica isn’t just a marketing trend. It’s backed by research and centuries of medicinal use. The ingredient’s bioactive compounds work on inflammation, collagen synthesis, and barrier recovery.
When used in well-formulated, fragrance-free products, it can noticeably reduce redness, strengthen the skin’s resilience, and improve comfort, especially for sensitive or reactive skin.
If you want a calmer, more stable complexion, a cica moisturizer or serum is a smart, low-risk addition to your routine. Look for Centella extract or madecassoside near the top of the ingredient list, keep your routine simple, and let consistency do the work.
