Centella Asiatica: The Botanical Authorised as Medicine

Most botanical extracts in skincare earn their place through marketing, not medicine. Centella Asiatica is the exception. Under the brand name Madecassol, medicinal preparations containing its triterpene extract have been authorised in Europe since the late 1960s, first for cutaneous use in 1968, then in oral form the following year, specifically for wound healing.

That distinction matters. An ingredient doesn't earn medicinal authorisation on the strength of tradition or a compelling backstory. It earns it by demonstrating, to a regulator, that it does what it claims to do. Dr Alison Jamieson selects every ingredient against exactly this kind of evidence hierarchy, and Centella Asiatica sits at the top of it: HIGH evidence tier, alongside niacinamide, retinol, and broad-spectrum SPF.

Two Mechanisms, One Ingredient

Centella Asiatica's activity comes from four related triterpenes: asiaticoside, madecassoside, asiatic acid, and madecassic acid. Together they do two distinct jobs in the skin, and it's the combination that makes the ingredient useful rather than either job alone.

The first is structural. Asiaticoside and madecassoside activate the TGF-β/Smad signalling pathway in fibroblasts, the cells responsible for producing collagen. Switching on this pathway increases collagen deposition and supports the extracellular matrix, the scaffolding that gives skin its firmness.

The second is anti-inflammatory. Madecassoside and asiatic acid suppress NF-κB signalling, which is the pathway that drives production of inflammatory messengers like TNF-α and IL-6. Calming this pathway reduces the low-grade inflammatory activity that accelerates visible ageing and contributes to reactivity in compromised skin.

Put simply: one mechanism tells skin to rebuild, the other tells it to stop overreacting. Few single botanical extracts are documented to do both.

Why This Belongs in a Day Cream, Not a Treatment Serum

It would be easy to assume an ingredient with wound-healing credentials belongs in a corrective, PM-only serum. Aliangé places Centella Asiatica in the Day Cream SPF 15 instead, and the logic is preventative rather than corrective.

Skin sustains genuine micro-damage every day, from UV exposure, from pollution, from the simple mechanical stress of a Queensland climate. That damage doesn't announce itself as a wound. It accumulates quietly as the kind of low-grade structural erosion that eventually reads as fine lines, uneven texture, and reduced firmness. An ingredient that supports collagen synthesis and calms inflammatory signalling is doing its most useful work when it's applied before that damage compounds, not after.

This is also why Centella Asiatica sits alongside Matrixyl 3000 in the same formula rather than replacing it. Matrixyl 3000 signals fibroblasts directly. Centella Asiatica supports the structural environment those fibroblasts are working in and calms the inflammatory noise that would otherwise interfere with the process. Neither ingredient does the other's job. The Day Cream SPF 15 is built on that division of labour, alongside broad-spectrum UV filters that address the primary driver of the damage in the first place, the same UV load documented in the Nambour Trial.

Where It Sits in the AM Protocol

The Day Cream SPF 15 is the final step of the AM Protocol: cleanse, treat with a serum, then finish with the Day Cream SPF 15. Centella Asiatica's role in that sequence is to work quietly in the background across every one of those daily applications, supporting the skin's structural resilience while the SPF filters handle the immediate UV threat. It is not a step you add. It is already doing its job as part of the step you are already taking.

This is consistent with how the AM Protocol is built more broadly: layered actives that each solve a specific, evidenced problem, in a fixed order, applied daily rather than sporadically. An extract authorised as medicine on the strength of decades of use is a reasonable inclusion in that kind of system. A trend ingredient with a single influencer testimonial is not.

Common Questions

Is Centella Asiatica the same as Gotu Kola?
Yes. Gotu Kola and Cica are common names for the same plant, Centella Asiatica. You'll see all three terms used interchangeably in skincare, though "Centella Asiatica" is the botanical name used on ingredient lists.

Does this mean the Day Cream SPF 15 can heal wounds?
No. The medicinal authorisation referenced here applies to specific pharmaceutical preparations of the triterpene extract, at concentrations and formulations governed by therapeutic-goods regulation, not to cosmetic skincare. In the Day Cream SPF 15, Centella Asiatica is included as a cosmetic ingredient to support the appearance of firmer, calmer skin, within a broader botanical complex alongside Rosemary and Echinacea.

Will Centella Asiatica help with redness?
Its anti-inflammatory action via NF-κB suppression is well documented, which is why it's a reasonable choice for skin that runs reactive. It works alongside the barrier-support ingredients already built into the AM Protocol rather than as a standalone treatment for redness.
