Green Tea & Centella Asiatica Cleansing Mousse

Green Tea & Centella Asiatica Cleansing Mousse from Skin by Render, built on Green Tea (EGCG). Below: what's in it, whether the active actually reaches the layer it needs to, where it goes in a routine, and what to expect.

Does Green Tea (EGCG) actually work on skin?

This is a different question from whether it works injected, and the answer is often different too — a molecule has to survive the stratum corneum before any of its biology matters. Full Green Tea (EGCG) breakdown →

Human clinical evidence

• Topical polyphenol trials report reduced UV-induced erythema and some sebum-regulating effect. Real, but modest, and mostly measured as protection rather than correction.

Correlative data

• Consistently well tolerated, which is why it appears in cleansers and calming products rather than as a headline active.
• Best understood as protective rather than corrective. It pairs sensibly under sunscreen in the morning, where reducing UV-induced inflammation is the whole job, and adds little at night when there is nothing to protect against.

How the mechanism reads

• An antioxidant with genuine anti-inflammatory signalling — but EGCG is unstable and degrades in light and air, so the concentration on the label is rarely the concentration on your face.
• The stability problem is the practical story. EGCG oxidises in light, air and warmth, and the visible tell is colour: a green-tea product that has gone brown has already lost much of what you paid for. Opaque, airless packaging is not marketing on this ingredient — it is the difference between an active product and a coloured one.

Does Centella Asiatica actually work on skin?

This is a different question from whether it works injected, and the answer is often different too — a molecule has to survive the stratum corneum before any of its biology matters.

Human clinical evidence

• Reasonable trial evidence for barrier repair, reduced redness and improved wound healing — mostly from madecassoside and asiaticoside, the isolated triterpenes rather than the whole extract.

Correlative data

• The backbone of Korean 'cica' formulation and widely reported to calm compromised, over-exfoliated skin.
• Its reputation comes from wound care rather than cosmetics, which is the right way round — this is a barrier-repair and calming-after-damage active, and it is at its best after retinoids, acids or sun rather than as a headline anti-ageing ingredient.

How the mechanism reads

• Read as a repair ingredient, not an anti-ageing one. It is what you pair WITH retinol or an acid to make that regimen tolerable — its value shows up as being able to keep using the strong thing.
• The activity sits in four triterpenes — asiaticoside, madecassoside, asiatic acid and madecassic acid — which is why the label matters more here than almost anywhere else in skincare. 'Centella extract' can mean a standardised fraction of those four, or it can mean leaf water. Products that state the fraction are making a checkable claim; products that say 'Centella' are not.

How to use Green Tea & Centella Asiatica Cleansing Mousse

Step 1 — Cleanse

First step, AM and PM. Everything else is wasted on unclean skin. This is a calm-it-down active. It earns its place after a retinoid, an acid or a day in the sun rather than as the thing driving change.

What to expect, and when

Immediate.
