The defining K-beauty soothing botanical — a small wetland plant whose extract (commonly labeled 'cica') drives one of the largest categories in Korean skincare. The active fraction is the triterpene complex (madecassoside, asiaticoside, asiatic acid, madecassic acid), with madecassoside the most-studied for wound-healing and barrier-repair effects. Now mainstream beyond K-beauty: Topicals, Versed, Beauty of Joseon, Skin1004, and Dr. Jart all build category lines around it.
Benefits
anti-inflammatory and barrier-repair via triterpene actives
stimulates collagen synthesis (asiaticoside)
calms post-acid, post-procedure, and rosacea-prone skin
Example uses
barrier creams
post-acne recovery
post-procedure soothing
sensitive-skin moisturizers
Mechanism of action
The active fraction is a complex of four pentacyclic triterpenes: asiaticoside and madecassoside (glycosides) and their aglycones asiatic acid and madecassic acid. Together they stimulate type I and III procollagen via TGF-β1 upregulation, accelerate wound-bed angiogenesis through fibroblast VEGF release, and suppress NF-κB-mediated keratinocyte inflammation. Madecassoside is the single most-validated of the four for barrier repair and post-procedure recovery; the others contribute additive anti-inflammatory and pro-collagen action.
Clinical evidence · High
Substantial RCT base on burn recovery, photoaging, atopic dermatitis adjunct, and scar remodelling — especially for standardised TECA (titrated extract of Centella asiatica) and madecassoside-isolate formulations.
Effective concentration range
0.1–5% standardised extract; up to 70% as aqueous base in K-beauty essences
Formulation notes
Cica extracts vary wildly in triterpene concentration. Madecassoside-isolated extracts (Skin1004 Madagascar Centella) outperform generic 'centella extract'. Pairs with niacinamide, panthenol, and hypochlorous acid in barrier-rescue stacks.
Watchouts
'Cica' on a label may mean trace centella extract or a heavily standardized triterpene complex — the gap is enormous. Look for named actives (madecassoside %, asiaticoside %).
'Cica' as a label term is genuinely meaningless without triterpene specification — a fraction of products in the K-beauty cica category use generic, sub-active extracts at trace levels. The molecule is real, the standardisation gap is the issue. Wild-harvest pressure in Madagascar is documented.
Market positioning
Sold as the K-beauty miracle soother — and unusually for a hyped category, the underlying molecule earns the hype. The honest caveat is that the label term 'centella' is doing a lot of work that only standardised extracts deliver on.
