Centella asiatica (cica)
Centella (you'll see it sold as 'cica') is marketed as a soothing, barrier-calming hero. Reviews are cautiously positive, but nearly all the promising data comes from lab dishes and animals, with very few human trials, and those often test it blended with other ingredients so no one can say what the cica itself did. Almost certainly harmless. Just not the proven miracle the packaging suggests.
what the evidence says
Reviews credit Centella with soothing and barrier effects but note most evidence is in-vitro or animal, with sparse human trials and many combination products.
