Centella for skin: 3 study checks

What does Centella research tell us about skin care?

Centella asiatica is a plant you'll see on lots of K-beauty labels. 🌿 So what has been tested?

One trial gave pregnant women a cream with Centella extract plus a few other ingredients, to see if it helped with stretch marks. Fewer women in the cream group got new stretch marks than in the group using a look-alike cream with nothing active in it.

Reference: Mallol et al., 1991

The catch: the cream had several ingredients, so nobody can tell how much of that came from Centella alone. 🤔

And stretch marks on a belly are a different question from redness or acne on a face. This one study can't speak for every face cream with Centella on the label.

How do you check a Centella skin claim?

Ask three questions before you trust it. 🔎 What was tested together with the Centella? Does the study match your skin concern? Was safety measured?

Each one takes a minute. Together they show whether a claim stays inside what the study really found.

1. What was tested together?

The trial cream had Centella extract, a form of vitamin E, and broken-down collagen and elastin. 🧪 It tested that whole mix, not Centella by itself.

Reference: Mallol et al., 1991

On a label, write down the exact ingredient name. Centella asiatica extract and madecassoside are different ingredients, each with its own page. Two different names aren't the same study ingredient. 🏷️

Note where the name sits in the list, and any amount the label gives. No amount? Then it's unknown. The spot in the list can't fill in a missing percent.

2. Does the study match your skin concern?

The trial followed 80 pregnant women and looked at stretch marks. 🤰 It didn't test a face serum for redness or acne.

Reference: Mallol et al., 1991

For a claim about your face, look for a trial on people that matches the ingredient, the formula and the face concern. If the paper you're shown answers a different question, the face claim still needs more clinical evidence. That only means this paper doesn't settle it; such research may exist elsewhere. 🔎

3. Was safety measured?

A trial that included pregnant women doesn't, by itself, show a cream is safe in pregnancy. ⚠️

This study measured stretch marks. It can't tell you whether a new Centella formula is safe during pregnancy or for a baby.

Reference: Mallol et al., 1991

Pregnant or breastfeeding? Ask your care team about the full formula first. Bring the ingredient list and directions, so you're asking about the exact product you'd use. 📋

Does a lab finding prove a Centella serum works?

Not by itself. 🔬 A 2021 review describes how Centella ingredients like asiaticoside and madecassoside act in skin disease models. That helps explain the idea.

It can't show that a finished face serum helps a real person's face. For that, a trial on people is needed.

Reference: Park, 2021

Madecassoside has its own page. 🌿 For a face claim, ask for the people study too. For red, easily upset skin, see the redness page.

What should you keep from a label check?

Three things: the exact ingredient name, the full formula, and the skin concern the study looked at. ✍️

A big promise like "repairs all skin" tells you less than one named study with a clear limit.
