What it is
An extract derived from the leaves of Lathyrus odoratus, the sweet pea plant. It contains natural compounds like flavonoids and phenolic acids that have antioxidant activity.
How it works
The extract provides antioxidant compounds that can neutralize free radicals on the skin's surface, potentially reducing oxidative stress. It may also have mild soothing properties due to its plant-based polyphenols.
Pros

Provides antioxidant benefits without common irritation, suitable for sensitive skin types.
Soothing potential
May help calm the skin due to its natural polyphenol content, though more research is needed.

Rarely used alone
It is almost always part of a blend, making it hard to know its individual contribution to a product's effects.
