Centella Asiatica is a small, creeping plant that grows in wet, swampy ground in warm parts of Asia, Africa and Oceania. It belongs to the parsley family and goes by a few other names, like Gotu kola, Indian pennywort and tiger grass. That last one comes from an old story about injured tigers rolling in it to heal their wounds. The plant has a long history in Ayurvedic and traditional Chinese medicine, and these days it’s all over skincare shelves, usually labeled cica.
So is Centella Asiatica good for sensitive skin? Yes, for most people it’s a good ingredient to try. It helps skincare hold onto water and calm down redness, and allergic reactions to it are rare.
There are 2 catches, though. Most products carry far less of it than the study that showed results, and a small number of people are allergic to it, which the usual quick patch test can miss. It also depends on what “sensitive” means for your skin, because that one word covers a few different problems.
What Centella Asiatica Does for Sensitive Skin
The parts that do the work are 4 compounds: asiaticoside, madecassoside, asiatic acid and madecassic acid. Asiaticoside is asiatic acid with a sugar chain attached, and madecassoside is madecassic acid with one.
In a 2016 study, 25 volunteers put creams made with the plant’s extract on their forearms twice a day for 4 weeks, at 2.5% and 5% strength. The 5% cream did best. Skin held more water, lost less of it through the surface, and showed an anti-inflammatory effect in a test that brings up mild redness on purpose. That’s what people mean when they call it calming: a better barrier and less redness.
The first catch is strength. When the Cosmetic Ingredient Review, the expert panel that reviews cosmetic ingredient safety in the US, put together its 2015 safety report, the industry survey it used showed the highest amount of the extract in leave-on face and neck products was 0.5%. That’s a tenth of what worked best in the study, and the study tested forearms instead of faces.
Studies on people who have sensitive skin are harder to read. A 2025 study looked at one product that combined centella with ceramides and panthenol, both moisturizing skin care ingredients on their own, so there’s no way to tell which one did the work.
Which Kind of Sensitive Skin It Helps
The expert definition of sensitive skin comes from a 2017 position paper by the International Forum for the Study of Itch. It describes stinging, burning, pain, itching or tingling in response to things that normally shouldn’t cause that. The skin can look normal or a little red, and the authors wrote that the cause is probably tied to the nerves.
The studies above measured water loss and redness. None of them looked at the nerve side. So the answer changes with how your skin behaves:
| Your Skin | How Well It Fits |
|---|---|
| Feels tight and dry, and stings more when it’s dry | Good fit. This is where the water-holding results apply. |
| Turns red easily | Some support. The redness result came from a forearm test on volunteers. |
| Stings or burns but looks normal | Not much evidence. The studies measured water loss and redness. Stinging wasn’t part of it. |
| Got touchy after a retinoid, acid or scrub | Good fit, once you’ve stopped the product that caused it. |
Rosacea and eczema are a separate case. The same definition says sensitive skin can’t be explained by a skin disease, so if you have either one, start with a dermatologist’s plan and treat cica products as an extra. In a placebo-controlled trial of 40 children with eczema, the kids using a centella cream got better, but so did the kids using a plain cream, and the difference between the 2 groups wasn’t significant.
When Centella Asiatica Can Make Things Worse
Cica has a reputation for being gentle, and for most people it is. Still, a small number of people are allergic to it, and for them a calming cream becomes the thing causing the rash.
The Cosmetic Ingredient Review’s safety verdict comes with a condition. It calls the ingredients from this plant safe “when formulated to be non-sensitizing,” because the panel was “concerned about the presence of constituents that could result in sensitization.” Put simply, some natural parts of the plant can trigger allergies, so how much is used and what else is in the formula both count.
The same report lists published allergy cases from 1985 through 2010, and a 2024 report described 2 more patients who reacted to both centella extract and fragrance allergens. Reactions like these are rare. The report also includes 6 patch tests on about 500 volunteers at normal cosmetic strengths, and none turned up an allergic reaction.
The 2024 cases carry a useful warning. A cream sold as calming cica can still contain fragrance, and fragrance causes reactions of its own. If a cica cream makes your skin worse, the plant might not be what’s doing it.
How to Try It Without a Reaction
You’ll see 24-hour patch tests recommended online, and for this ingredient that’s too short. Allergic reactions on the skin can take days to show up. In one of the published cases, the patch test reaction appeared at 48 hours and got stronger by day 3 or 4, so a 24-hour test would have missed it.
The American Academy of Dermatology’s method takes longer:
- Pick a quarter-sized spot on the underside of your arm or the bend of your elbow, somewhere it won’t get rubbed or washed off.
- Put the product on twice a day for 7 to 10 days, using the same amount you’d use on your face.
- If the spot turns red, itchy or swollen, wash it off gently and stop using it. A cool compress or petroleum jelly can help it settle.
- No reaction after 7 to 10 days means you’re fine to use it.
Check the label before you start:
- Look for the real ingredient names, like Centella Asiatica Extract, Leaf Extract, madecassoside or asiaticoside. “Cica” on the front of the box isn’t an ingredient name.
- I’d skip anything with fragrance (listed as “fragrance” or “parfum”) or essential oils while you’re testing, and try 1 new product at a time, so if something reacts you’ll know what caused it.
If your skin has been reactive lately, let us know before your facial and mention anything that’s made it flare, cica included, so we can steer clear of it. Our facials start at $85 for the 45-minute signature, and if your skin runs tight and dry, ask about Refine + Hydrate or Hydrate + Firm ($115 each).
And if a patch test does flare up, write down the product name before you throw it out, so you can tell your dermatologist exactly what caused it.
