Centella Asiatica (CICA): Benefits, Science & How to Use
Centella asiatica — marketed as CICA — became a K-beauty phenomenon for good reason. This plant has been used in traditional medicine for centuries for wound healing, and modern research confirms it. Centella contains four active terpenoids that independently reduce inflammation, stimulate collagen, and accelerate skin repair. This guide breaks down the science behind each compound and how to use CICA effectively in your routine.
⚡ TL;DR
Centella asiatica contains 4 active compounds: madecassoside (anti-inflammatory), asiaticoside (wound healing), madecassic acid (collagen synthesis), and asiatic acid (skin strengthening). Together they're called TECA. Clinical studies show CICA reduces redness by 42% and improves wound healing by 30%. It's gentle, non-irritating, and safe for all skin types.
📖 What Is Centella Asiatica?
Centella asiatica (also called gotu kola, tiger grass, or pennywort) is a herbaceous plant native to Southeast Asia. According to a 2013 comprehensive review in the Indian Journal of Pharmaceutical Sciences, it has been used for over 3,000 years in Ayurvedic and traditional Chinese medicine for wound healing and skin repair. The plant's leaves contain four triterpene compounds — collectively called Titrated Extract of Centella Asiatica (TECA) — that provide its dermatological benefits. In skincare, CICA refers to products containing these centella extracts, marketed under the abbreviation derived from "cicatrization" (the process of scar formation).
The 4 Active Compounds: How TECA Works
According to a 2015 review in Phytomedicine (DOI: 10.1016/j.phymed.2015.07.004), centella's benefits come from four distinct terpenoid compounds working synergistically:
| Compound | Primary Function | Mechanism | Skin Benefit |
|---|---|---|---|
| Madecassoside | Anti-inflammatory | Inhibits NF-κB pathway, reduces IL-1β and TNF-α | Reduces redness, calms irritation |
| Asiaticoside | Wound healing | Stimulates Type I collagen synthesis, increases angiogenesis | Faster healing, reduced scarring |
| Madecassic Acid | Collagen synthesis | Activates TGF-β signaling in fibroblasts | Improved firmness, elasticity |
| Asiatic Acid | Antioxidant | Free radical scavenging, strengthens barrier lipids | UV protection support, barrier reinforcement |
According to a 2020 clinical study in the Journal of Cosmetic Dermatology (DOI: 10.1111/jocd.13550), topical TECA application for 8 weeks reduced skin redness by 42% and improved barrier function (measured by TEWL) by 28% in participants with sensitive skin.
Who Benefits Most from CICA
Sensitive and Reactive Skin
CICA is ideal for skin that flushes, stings, or reacts to new products. According to dermatological research, madecassoside inhibits the inflammatory cytokines that trigger sensitivity reactions. See our sensitive skin routine for a complete plan.
Post-Procedure Recovery
According to a study in Dermatologic Surgery, CICA cream applied after laser treatments reduced redness duration by 35% and improved healing time. Dermatologists frequently recommend centella-based products for post-peel, post-laser, and post-microneedling recovery.
Retinol Buffering
According to dermatological protocols, CICA is one of the best ingredients to pair with retinol. It soothes the irritation, flaking, and redness that retinol causes during the retinization period. Apply CICA cream over retinol as a barrier buffer.
Acne-Scarred Skin
Asiaticoside accelerates wound healing and stimulates collagen deposition specifically at wound sites. According to clinical data, this reduces the depth and discoloration of acne scars over 8-12 weeks of consistent use.
Barrier-Damaged Skin
If over-exfoliation, harsh cleansers, or environmental stress have compromised your barrier, CICA supports barrier repair alongside ceramides. Centella reduces the inflammation while ceramides rebuild the lipid matrix.
Check if your CICA product has all 4 compounds
Not all centella products contain the full TECA profile. Some use only centella extract with trace amounts. SkinGuard scans ingredient lists and identifies which centella compounds are present and their INCI position.

As a Serum (After Cleansing)
Apply CICA serum after cleansing and toning, before heavier creams. Layer under hyaluronic acid or niacinamide serums. CICA plays well with almost all actives.
As a Moisturizer (AM & PM)
Most popular format. CICA moisturizer replaces your regular cream. It provides both hydration and anti-inflammatory protection. Use as your main moisturizer when skin is irritated, recovering, or during retinol adjustment.
As a Spot Treatment
Apply concentrated CICA balm on specific irritated areas: post-acne inflammation, retinol patches, windburn, or minor cuts. The concentrated form accelerates localized healing.
CICA Compatibility Chart
| Ingredient | Compatible? | Notes |
|---|---|---|
| Retinol | ✅ Excellent | CICA reduces retinol irritation, apply after retinol |
| Niacinamide | ✅ Excellent | Both strengthen barrier, complementary mechanisms |
| Hyaluronic Acid | ✅ Excellent | HA hydrates, CICA soothes — layer HA first |
| Vitamin C | ✅ Good | Can use together, vitamin C first due to lower pH |
| AHA/BHA | ✅ Good | CICA soothes post-exfoliation irritation |
| Ceramides | ✅ Excellent | CICA calms, ceramides rebuild — ideal combo |
According to dermatological literature, centella asiatica is one of the most universally compatible skincare ingredients. It has no known negative interactions with any common active ingredient, making it safe to add to virtually any routine.

What does centella asiatica do for skin?+
Centella asiatica contains four active terpenoids: madecassoside and asiaticoside reduce inflammation and redness, while madecassic acid and asiatic acid stimulate collagen synthesis and wound healing. Together, they soothe irritation, strengthen the barrier, and support skin repair.
Is centella asiatica good for acne?+
Yes. Centella's anti-inflammatory properties reduce acne redness and swelling without drying skin. Asiaticoside specifically accelerates wound healing, helping acne lesions heal faster with less scarring.
Can I use CICA with retinol?+
Yes — it's an ideal combination. CICA soothes the irritation retinol causes and supports barrier repair during retinization. Apply retinol first, then CICA cream as a buffer. Many dermatologists specifically recommend this pairing.
What is the difference between CICA and centella?+
They are the same ingredient. CICA is a marketing abbreviation derived from "cicatrization" (wound healing). Centella asiatica is the botanical name. Products labeled CICA contain centella asiatica extracts.
Can I use CICA every day?+
Yes. Centella asiatica is gentle enough for twice-daily use, morning and night. It has no photosensitivity effects, causes no purging, and is safe for all skin types including sensitive and rosacea-prone skin.
