Centella (cica): does it really calm red skin?

Centella (often sold as "cica") may help calm red skin, but the evidence in people is still limited. If your face flushes often, ease off the irritation first rather than counting on centella. When women with sensitive skin used a cream combining centella, ceramides and panthenol for four weeks, their redness went down (Su et al., 2025). The study had no comparison group and looked only at before and after, so the change can't be pinned on centella alone.

Say "soothing ingredient" and cica comes up first. But what exactly does it calm, and how?

How does centella calm red skin?

Redness is generally thought to start where the barrier has weakened. A thin barrier lets small triggers raise inflammatory signals easily; vessels dilate and the spot turns red and hot.

Centella asiatica's actives are pentacyclic triterpenes, mainly madecassoside and asiaticoside. Madecassoside and asiaticoside have been reported to damp inflammation and to support collagen synthesis and wound closure (Bylka et al., 2013). Most of that evidence, though, comes from lab and animal studies.

What changed on sensitive skin?

When women with sensitive skin used a cream pairing centella leaf extract with ceramide NP and panthenol for four weeks, their sensitivity score (SS-10) fell by 76%, and redness, stinging, itching and tightness all eased (Su et al., 2025). Water loss (TEWL) dropped in weeks one and two but was no longer meaningfully different from the start by week four. The centella cream eased redness, but only in a before-and-after study without a comparison group. The cream's maker funded the study, and with three ingredients in the jar, the result can't be put down to centella alone.

How to use it

Centella doesn't compete with strong actives; it eases the irritation beside them. When skin is red and reactive, pare the strong actives back for a while and protect the barrier with gentle cleansing and a soothing centella-and-panthenol moisturizer. How soothing and barrier ingredients relate is in panthenol and niacinamide, and how long that takes is in how long the barrier takes to come back.

So: centella belongs beside less irritation

In lab and animal studies, centella's triterpenes have been reported to damp inflammation (Bylka et al., 2013). Women who used a centella cream for four weeks saw their sensitivity score fall by 76%, but there was no comparison group and the cream also held ceramides and panthenol (Su et al., 2025). Think of centella less as something that erases redness and more as a soothing moisturizer to keep close while you cut back irritation. If redness is frequent, ease off strong actives and give a centella moisturizer four weeks before you judge it.

One step today

• When your face is red and hot, pare back strong actives for a while. This hasn't been tested in a trial. Note what you set aside, and after three days check whether the heat right after cleansing has eased. If redness is unchanged after several weeks, or heat and flare-ups keep coming back, see a dermatologist.
• Protect the barrier with a soothing centella (cica) and panthenol moisturizer. In a study, a cream combining centella, ceramides and panthenol used for four weeks lowered redness, stinging, itch and tightness (Su et al., 2025). It had no comparison group, so the change cannot be put down to centella alone, but keep four weeks as the point where you judge it. If redness is unchanged at four weeks, see a dermatologist.
• Introduce any new soothing product (centella, panthenol, madecassoside) one at a time and watch how skin responds. The one-at-a-time approach hasn't been tested in a trial. Give each one a week before adding the next; that is how you know what caused a reaction. If the spot where you applied it itches or swells red, stop that product.
