Ingredient review
Lemongrass Extract
INCI: Cymbopogon Flexuosus Herb Extract
Lemongrass extract can help tone oily skin and provide a fresh scent, but it may irritate sensitive skin due to its natural citral content.
In plain English
Lemongrass extract is made from the leaves of a tropical grass. In skincare, it's used mainly for its light astringent effect—it can help tighten pores and reduce excess oil. It also has natural antimicrobial properties, which may help with acne-prone skin. However, because it contains compounds like citral, it can cause stinging or redness on sensitive or broken skin. It's often added for its fresh, citrusy scent.

What it is
A water- or oil-based extract obtained from the herb Cymbopogon flexuosus, a type of lemongrass native to India and Southeast Asia. It contains citral, geraniol, and other volatile oils.
How it works
The extract's astringent compounds cause a mild tightening of skin tissue, temporarily reducing the appearance of pores. Its antimicrobial activity may help reduce surface bacteria that contribute to acne. The scent provides a natural fragrance alternative to synthetic perfumes.
Pros

Cons and cautions
Can irritate sensitive skin
The citral content may cause stinging, redness, or burning, especially on broken or reactive skin.

Best for
