Centella Asiatica for Skin: What the Research Shows and How to Compare Cica Formulas


Centella asiatica is everywhere in Korean skincare, but comparing Cica products can become confusing surprisingly quickly.

One ampoule may advertise 100% Centella Asiatica extract, another cream may contain 70% Centella leaf water, while another formula uses a much smaller percentage alongside madecassoside, asiaticoside, and other Centella-derived compounds.

Does the highest Centella percentage actually mean the strongest—or best—formula?

To answer that, it helps to understand what Centella contains, what human research actually supports, and what those very different percentages on Korean skincare labels really represent.

What Exactly Is Centella Asiatica?

Centella Asiatica—also known as gotu kola and commonly called Cica in skincare—is a botanical with a long history of traditional use that is now widely incorporated into dermatologic and cosmetic formulations.

Much of its skin-related research centers on four pentacyclic triterpenes:

  • Asiaticoside
  • Madecassoside
  • Asiatic acid
  • Madecassic acid

These compounds are important because much of the research associated with Centella's effects on inflammation, oxidative stress, collagen-related pathways, and wound repair involves either these triterpenes or extracts containing them.

But "Centella extract" and "individual Centella-derived compounds" are not interchangeable terms. A botanical extract contains a mixture of constituents, and its composition can vary depending on the plant material, extraction method, and standardization.

That distinction becomes especially important when comparing Cica products.

Which Compounds in Centella Matter?

Asiaticoside and madecassoside are triterpene glycosides, while asiatic acid and madecassic acid are related aglycones. Laboratory and clinical research has investigated these compounds for their roles in inflammatory signaling, oxidative stress, fibroblast activity, collagen-related pathways, and wound repair.

This does not mean a cosmetic containing unspecified Centella extract will reproduce the effects observed with an isolated compound or standardized preparation.

Knowing which form of Centella a product contains therefore provides more useful information than seeing the word “Cica” alone.

What Does Human Research Actually Show?

Centella has a substantial history in wound-related research, while evidence for many everyday cosmetic claims is less extensive.

Skin Recovery and Visible Redness

Some of the more relevant human evidence comes from controlled skin-recovery settings.

Clinical research summarized in a 2024 review includes Centella preparations studied for wounds, burns, scars, and post-procedure recovery. These studies support biological interest in Centella for tissue-repair and inflammation-related processes.

However, evidence from standardized or medical preparations should not automatically be transferred to every cosmetic Cica serum or cream.

Hydration and Barrier Support

A small double-blind clinical trial involving 30 Indonesian batik workers with dry skin compared creams containing Centella Asiatica or ceramide over four weeks.

The Centella cream significantly improved several measures of stratum corneum hydration and skin acidity. The researchers reported no significant difference between the Centella and ceramide treatments in overall skin-barrier improvement, although the individual measurements that changed significantly were not identical between groups.

The study is small and does not establish that Centella is equivalent to ceramides in all moisturizers, but it provides direct human evidence supporting a role in skin hydration.

Collagen and Visible Skin Aging

Centella-derived compounds have also been investigated in photoaged skin.

A randomized double-blind study involving 20 women tested a topical formula containing 5% vitamin C and 0.1% madecassoside for six months. Improvements were reported in wrinkles, firmness, roughness, hydration, elasticity, and structural measures of photoaged skin.

The important limitation is that this was a combination formula. It cannot tell us how much of the observed improvement was attributable to madecassoside independently of vitamin C.

What Does the Evidence Not Tell Us Yet?

Human evidence is stronger for wound recovery and related settings than for many broad cosmetic claims associated with Cica.

Studies also investigate different materials—from whole and standardized extracts to isolated triterpenes and combination formulas—so their results cannot automatically be applied to every Centella cosmetic. Reviews continue to call for more rigorous clinical trials, particularly for skin conditions beyond wound healing.

Centella should therefore not be presented as a proven acne treatment or a guaranteed collagen-stimulating ingredient simply because it appears on a product's ingredient list.

Does a Higher Centella Percentage Mean a Better Product?

This is where comparing Korean Cica products gets interesting.

Consider these four descriptions:

100% Centella Asiatica extract
70% Centella Asiatica leaf water
3.5% Centella Asiatica extract
Individually disclosed Centella-derived compounds

They do not necessarily measure the same thing.

A formula based almost entirely on a botanical extract can contain a very high percentage of Centella. Another product may contain less whole extract while separately incorporating madecassoside, asiaticoside, asiatic acid, or madecassic acid alongside other functional skincare ingredients.

Centella leaf water is also not automatically equivalent, percentage for percentage, to a Centella extract or an isolated triterpene.

So 100% does not automatically mean more effective than 70%, and 70% does not automatically mean more effective than 3.5%.

The number becomes meaningful only when you know what material the percentage actually describes and what the rest of the formula contributes.

That is why choosing a Cica product by the largest number on the bottle can miss what is most useful about the formula.

What to Look for in a Centella Formula

When comparing Cica skincare, focus on four things:

  • What the percentage measures — whole extract, leaf water, a complex, or an individual Centella-derived compound.
  • Named Centella compounds — madecassoside, asiaticoside, asiatic acid, and madecassic acid provide more specific information about what the formula contains.
  • Supporting ingredients — ceramides, panthenol, humectants, and other ingredients can substantially change what the finished product is designed to do.
  • The complete formula and intended use — a minimalist ampoule, hydrating serum, and barrier cream can serve different purposes even when all contain Centella.

Product Name Best For Formula Details Key Feature
SKIN1004 Madagascar Centella Ampoule Sensitive, Irritated & Reactive Skin 100% Centella Asiatica Extract  Minimalist Cica Formula
TOSOWOONG Madagascar Centella Cream Dry, Compromised Barrier 70% + 9 Cica Actives + 3 Ceramide Complex Centella + Ceramide Barrier Care
PURITO Wonder Releaf Centella Serum Unscented Sensitive, Dehydrated & Redness-Prone Skin ~3.5% Centella Extract Multi-Ingredient Hydrating Serum
Torriden Balanceful Cream Combination & Sensitive Skin 4 Centellosides (0.5-1.6% Each) + Panthenol 0.35-0.85%  Centelloside-Focused Moisturizer

For a Minimalist Cica Formula: SKIN1004 Madagascar Centella Ampoule

• Best for: Sensitive, irritated, and reactive skin

This ampoule takes the simplest approach among the four products: the verified formula is centered on 100% Centella Asiatica extract, without layering in multiple treatment actives.

The 100% figure is best understood as a formula-composition claim, not proof that the ampoule is more effective than a product containing 70% Centella leaf water or smaller amounts of individual Centella-derived compounds.

Its advantage is simplicity. For someone who wants a straightforward Centella-focused step without a complicated supporting formula, this is the clearest minimalist option among these four.

Choose this if you want a simple, Centella-focused ampoule rather than a multi-active serum or barrier cream.

For Centella Plus Barrier Care: TOSOWOONG Madagascar Centella Cream

• Best for: Dry, compromised, and sensitive skin

TOSOWOONG contains 70% Centella Asiatica Leaf Water (706,580 ppm), plus nine Centella-derived actives, including asiatic acid, madecassic acid, asiaticoside, and madecassoside. The verified formula also contains a three-ceramide complex.

This creates a different formulation strategy from SKIN1004. Instead of centering almost the entire product on a single Centella extract, the cream combines Centella leaf water and other Centella-derived ingredients with barrier-supportive ceramides.

The formula is also verified free of fragrance and artificial colorants.

Choose this if you want Centella in a more comprehensive, barrier-focused cream, especially when dryness is a priority.

• Where to buy: Amazon

Hydration and Multi-Ingredient Care: PURITO Wonder Releaf Centella Serum Unscented

• Best for: Sensitive, dehydrated, and redness-prone skin

The verified formula contains about 3.5% (34,860 ppm) Centella Asiatica extract, plus peptides and sodium hyaluronate.

At first glance, 3.5% may look modest beside 70% or 100%. But PURITO is designed as a broader hydrating serum rather than a near-single-ingredient Centella ampoule.

That makes the lower headline number less useful as a measure of overall formula quality. Here, Centella sits within a multi-ingredient system that also provides humectant and skin-conditioning support.

Choose this if you want Centella in a broader hydrating serum, rather than choosing primarily based on the highest Centella percentage.

• Where to buy: Amazon

For Individually Disclosed Centella Actives: Torriden Balanceful Cream

• Best for: Combination and sensitive skin

Torriden takes a different approach by disclosing ranges for four Centella-derived actives: Madecassoside (0.50–1.15%), Asiaticoside (1.00–1.60%), Asiatic Acid (0.90–1.35%), and Madecassic Acid (1.00–1.50%), as well as Panthenol at 0.35–0.85%.

Instead of relying on a single large generic Centella percentage, this gives readers information on several specific compounds that appear prominently in Centella research.

The formula is also fragrance- and essential-oil-free, adding another practical consideration for people seeking a sensitive-skin moisturizer.

Choose this if you prefer a moisturizer with individually disclosed Centella-derived actives plus panthenol, rather than a formula marketed primarily around a single high extract percentage.

Ingredients That Pair Well with Centella Asiatica

  • Hyaluronic Acid — Provides humectant hydration without duplicating Centella's primary role.
  • Ceramides — Supply barrier lipids while Centella adds a separate soothing and recovery-focused component.
  • Panthenol — Adds humectant and skin-conditioning support, particularly useful when dryness and discomfort occur together.
  • Retinol or Retinal — A gentle Centella formula can complement a retinoid routine when maintaining hydration and skin comfort is important.
When the skin is already highly irritated or barrier-compromised, adding more actives is not necessarily the priority. A simpler routine centered on gentle cleansing, adequate moisturization, and sun protection may be more appropriate until the skin feels comfortable again.

Nutrients That Support Normal Skin Repair and Structure

  • Vitamin C — Required for normal collagen synthesis and connective-tissue formation.
  • Protein — Provides amino acids needed to build structural proteins involved in normal tissue maintenance.
  • Zinc — Supports normal cell division, protein synthesis, and wound-healing processes.

These nutrients support normal skin physiology; consuming them does not reproduce the effects of topical Centella or deliver its triterpenes to the skin.

Frequently Asked Questions

.Is 100% Centella better than 70% Centella?

Not necessarily. The percentages may refer to different materials, such as an extract or leaf water, while other products disclose individual Centella-derived compounds. They should not be treated as a universal potency scale.

Is Centella Asiatica good for acne-prone skin?
Centella can fit into an acne-prone routine when soothing and skin comfort are priorities, but evidence supporting its use as an acne treatment remains limited. It should not replace established acne treatments.

Can Centella Asiatica be used with retinol?
Centella can be incorporated into a retinoid routine, particularly through a gentle hydrating or moisturizing formula when dryness and discomfort are concerns.

Is Centella Asiatica suitable for sensitive skin?

Centella is frequently used in products designed for sensitive skin, but the complete formula still matters. Fragrance, essential oils, preservatives, and other ingredients can affect individual tolerability.
