What it is
A natural extract derived from the flowers, leaves, and stems of Sideritis perfoliata, a Mediterranean plant in the mint family. It contains flavonoids, phenolic acids, and other antioxidant compounds.
How it works
The extract provides antioxidant activity by neutralizing free radicals—unstable molecules that can damage skin cells and accelerate aging. It also appears to have anti-inflammatory effects, which can help calm redness and irritation. In a formulation, it works alongside other ingredients to support the skin's barrier and overall resilience.
Pros

Its anti-inflammatory properties can help reduce redness and calm stressed skin, making it suitable for sensitive types.
Cons and cautions
Limited research
