Ingredient review
Lemongrass Leaf/Stem Extract
INCI: Cymbopogon Schoenanthus Leaf/Stem Extract
Lemongrass extract adds a fresh scent and mild astringent action, but can be irritating for sensitive skin.
In plain English
Lemongrass extract is made from the leaves and stems of the lemongrass plant. In skincare, it's used mainly for its fresh, citrusy smell and its ability to help tighten pores and reduce excess oil. It also has natural antimicrobial properties, which can help keep skin clean. However, because it contains compounds that can be irritating, it's best for normal to oily skin types and should be used in lower concentrations on sensitive skin.

What it is
Lemongrass leaf/stem extract is a natural ingredient derived from the Cymbopogon schoenanthus plant, commonly known as lemongrass. It is obtained by extracting the leaves and stems, typically using water or alcohol, to capture its aromatic and active compounds.
How it works
In cosmetic products, lemongrass extract works primarily as an astringent, meaning it can help tighten skin and temporarily reduce the appearance of pores. Its antimicrobial activity comes from compounds like citral and geraniol, which can help reduce surface bacteria. It also provides a natural fragrance that can make products feel refreshing.
