What it is
Madecassoside is one of the main biologically active compounds of Centella asiatica, the plant known as gotu kola or Asian pennywort. Chemically it is a pentacyclic triterpenoid saponin, a trisaccharide (three-sugar) derivative of madecassic acid, with the molecular formula C48H78O20. In skincare it is used as an antioxidant and skin-conditioning agent with a well-documented soothing reputation, and it is frequently paired with the related centella compound asiaticoside in calming formulas. It is especially common in Asian products aimed at sensitive or easily irritated skin.
Safety & warnings
Madecassoside is generally well tolerated and is most often chosen precisely for sensitive, reddened, or stressed skin, with reported skin benefits at low use levels. As a single purified plant constituent it is less likely to carry the variability of whole-extract botanicals, though anyone with a known sensitivity to Centella asiatica or gotu kola-derived ingredients should approach products containing it with the usual caution and consider a patch test.
Origin & sourcing
Madecassoside is a plant-derived compound naturally produced in Centella asiatica, a herb native to tropical and temperate regions including the Indian subcontinent, Southeast Asia, parts of Australia, and wetlands of the southeastern United States. It is one of a group of triterpene glycosides (centelloids) the plant makes through the isoprenoid pathway, in which a triterpenoid core is conjugated with sugar chains; for cosmetic use it is obtained by extraction from the plant.
History
Centella asiatica has a long record of use in traditional medicine across South and Southeast Asian cultures, particularly for skin conditions and minor wounds. The plant's triterpene constituents, including madecassoside (historically also called brahmoside) and asiaticoside, were the subject of chemical examination by around the mid-twentieth century, and roughly 124 compounds have since been identified from the plant.
Questions everyone asks
What is madecassoside good for in skincare?
It is a centella-derived ingredient used to soothe and condition skin and to provide antioxidant support. It is especially common in products formulated for sensitive or easily irritated skin.
Where does madecassoside come from?
It is a natural compound extracted from Centella asiatica, the plant known as gotu kola or Asian pennywort. It is one of the plant's main triterpene saponins.
What is the difference between madecassoside and asiaticoside?
Both are triterpenoid saponins from Centella asiatica and are often used together. They differ in their underlying acid and sugar structure: madecassoside derives from madecassic acid, asiaticoside from asiatic acid.
