Centella Asiatica / Madecassoside (Cica)

Centella Asiatica Extract / Madecassoside / Asiaticoside

Centella is overused in marketing, but the core idea is solid: soothing, barrier support, and wound-healing pathways. It is not magic, but it is useful in irritated routines.

Moxie's Take

"I already use a few other ingredients for skin barrier protection, but I did start off with this one first, really liked how gentle and calming it was for my skin. Worth exploring if your barrier needs help. "

What It Is

Centella (often labelled "cica") is the calming ingredient K-beauty built a reputation on — and underneath the marketing, the core idea holds up: it's genuinely soothing and may support wound healing. It is less about forcing change and more about making the skin function normally again.

For Moxie’s audience, this category matters because irritated skin does not just look worse; it responds worse to every active layered on top.

How It Works

Centella triterpenes such as madecassoside and asiaticoside can modulate inflammation, antioxidant responses, fibroblast activity, and collagen-related wound repair pathways.

The Evidence

Evidence: Moderate· Several small human studies in wound healing, irritation and barrier support, backed by a larger laboratory literature.
GradeB — Moderate evidence
VolumeSeveral small human studies in wound healing, irritation and barrier support, backed by a larger laboratory literature.

Evidence is strongest for barrier and hydration outcomes rather than dramatic anti-aging. Clinical relevance depends on the whole formula: humectants need occlusives/emollients, and barrier lipids work best when the product avoids fragrance and irritants.

A split-face, double-blind, randomized, placebo-controlled trial in 30 post-laser-resurfacing patients found 0.05% Centella asiatica extract (ECa 233) significantly reduced erythema versus placebo (Pumthong G, et al., J Cosmet Dermatol).

How to Use

ConcentrationVaries; look for madecassoside/asiaticoside standardisation
FrequencyOnce or twice daily, especially during periods of irritation or active-heavy routines.
AM / PMBoth AM and PM
LayeringUse watery cica products before moisturiser and cica balms after serums as the moisturising step.

Tips

Apply after watery serums and before sunscreen in the morning, or as a moisturising/barrier step at night. Pair with SPF during the day. Patch test first if you have a botanical or plant allergy — centella is well tolerated overall, but sensitivity to it does exist.

It works well applied directly onto irritated or freshly treated skin, often as the step right after a procedure or an active-heavy night. SPF isn't specifically tied to centella use, but keep it in your daytime routine as normal if you're also using actives elsewhere.

Signs it's not agreeing with you: new stinging, redness, or bumps where there weren't any before — stop and patch test a lower-concentration formula.

Who It Suits

Works Well For

redness-prone, barrier-damaged, post-acne, post-procedure support when permitted

Use With Caution If

Botanical allergy exists; patch test if reactive.

Darker Skin Tones (Fitzpatrick IV–VI)

Post-inflammatory hyperpigmentation (PIH) risk is higher for darker skin tones with active ingredients, heat- or light-based devices, and any procedure that causes inflammation. This does not mean avoid — it means patch test, go slower, and confirm your provider has real experience treating Fitzpatrick IV–VI skin before an energy-based or ablative treatment.

Specific To This Ingredient

For Fitzpatrick III-VI, irritation control matters. Any ingredient that causes inflammation can worsen PIH, even if it is marketed as brightening or anti-aging.

Pregnancy Note

Generally compatible, but consult doctor for pregnancy/nursing if skin condition is medical

Frequently Asked Questions

Is centella the same as cica?

Yes — cica is the popular shorthand for centella asiatica (and its actives madecassoside and asiaticoside) used in Korean skincare marketing.

When should I use centella in my routine?

It works well anytime skin feels irritated, but it's especially useful as a post-procedure or post-active recovery step, with comfort felt quickly and barrier changes over 2-8 weeks.

Can centella replace my moisturiser?

Not on its own — it's a soothing support ingredient, best paired with barrier ingredients like ceramides or panthenol rather than used as a full moisturiser replacement.

The Verdict

Not For Me

My post-treatment calm-down step.
