Centella asiatica: Myth or Real Effect on Skin

The myth: "cica-cream" fixes everything. The data exist and are serious—but they relate to standardized extracts, not to creams that display the word.

The plant, and its names

Centella asiatica, also called gotu kola or tiger grass—the latter name comes from a legend according to which tigers would roll in it to heal their wounds. It has been used for centuries in traditional Indian and Chinese medicine.

In cosmetics, it's its aerial parts that are of interest, for four compounds: asiaticoside, madecassoside, asiatic acid, and madecassic acid. They are collectively referred to as "TECA" or "standardized centella extract."

The gap between study and pot

Available studies relate to standardized extracts, at known concentrations, applied according to precise protocols. They describe an action on soothing and on the quality of the surface.

A commercial cream that mentions "centella asiatica" in its list may contain a standardized extract at 5%, or a trace of centella water at the end of the list. These are two different products bearing the same word, and nothing on the packaging always makes it possible to distinguish them.

What is well documented

The soothing of reactive skin, using standardized extracts. This is the most solid ground and it is real: Korean skincare products that popularized the ingredient use it precisely for this, on skin weakened by overly active routines.

What is observed: less discomfort redness, better tolerance, a quicker return to comfort after an aggression. Over four to six weeks, with a properly dosed product.

What is less documented

Everything related to firmness and signs of aging. The mechanisms mentioned come from cellular studies and oral administration work, not from the local application of a cream. It is a lead, too often presented as a result.

The word "cica," which has become a selling point, refers to no regulatory definition. A "cica" cream may contain no centella extract: it denotes a commercial promise, not a composition.

How to choose a centella-based product

Look for "Centella asiatica extract" in the first third of the list, or better yet, the mention of a specific compound—madecassoside, asiaticoside—which indicates a standardized extract. A displayed percentage is a good sign, even a modest one.

For sensitive skin, an aqueous serum is preferable to a rich cream: fewer excipients, and thus fewer sources of reaction. It's often the excipient, not the active ingredient, that causes problems for this skin profile.

So, myth or real effect

Real effect on soothing, myth on the rest, and a considerable gap between what research describes and what the shelf sells. It's an ingredient that deserves its reputation provided you know which one you're buying.

What Traditional Chinese Medicine used it for

Centella asiatica has been used for centuries in Asia, both orally and topically. Traditional Chinese Medicine and Ayurveda attribute broad uses to it, many of which are for medical care rather than cosmetic.

This long history explains its reputation, and it also explains the shift: what was described for medicinal use ends up on cream packaging, without the dosages or administration methods being comparable.

Antioxidant properties

Centella compounds exhibit antioxidant activity measured in the laboratory. On the skin, this means a contribution to protecting the surface film against unstable molecules produced by exposure and pollution.

It is a fundamental, slow contribution, difficult to isolate in a complete formula. It does not replace a sun filter, which acts upstream where an antioxidant limits downstream damage.

Using centella asiatica in practice

As an aqueous serum in the morning or evening, on clean skin, before cream. Two applications per day on reactive skin, one on normal skin. It combines with most active ingredients without specific precautions.

It is particularly suitable for periods of fragility: after exposure, upon return from cold, or during the introduction of a strong active ingredient. This is its best use, and it is well supported by what is known.

On blemish-prone skin and complexion

On acne-prone skin, it is often well tolerated and can help with comfort during a drying treatment. It does not act on the cause of imperfections, and nothing in the data suggests otherwise.

For the complexion, a more even appearance is reported after several weeks, which likely stems from a return to comfort rather than a pigmentary action. Centella asiatica cosmetic products are valuable for what they soothe, not for what they correct.
