Ingredient review
Mint Bush Leaf Extract
INCI: Prostanthera Rotundifolia Leaf Extract
A gentle botanical extract with antioxidant potential, but research on its specific skin benefits is still limited.
In plain English
This is an extract from the leaves of the Australian mint bush, a plant known for its aromatic leaves. In skincare, it's used mainly to provide antioxidant protection (helping to defend skin from environmental damage) and to offer a mild soothing effect. Because it's a natural plant extract, its exact composition can vary, and there isn't a lot of published research specifically on this ingredient for cosmetic use.

What it is
A natural extract obtained from the leaves of Prostanthera rotundifolia, a shrub native to Australia. The extract contains various plant compounds, including essential oils and polyphenols, which are thought to contribute to its antioxidant activity.
How it works
The polyphenols and other bioactive compounds in the extract can neutralize free radicals, potentially reducing oxidative stress on the skin. This may help protect skin cells from environmental aggressors like pollution and UV exposure. The extract may also have mild anti-inflammatory properties, which can help calm irritated skin.
