What it is
An extract obtained from the seeds of Rudbeckia hirta, commonly known as black-eyed Susan. It contains flavonoids, phenolic acids, and other plant compounds with antioxidant and anti-inflammatory potential.
How it works
The extract's antioxidant compounds help neutralize free radicals (unstable molecules that can damage skin cells). Its anti-inflammatory properties may reduce redness and irritation by calming the skin's immune response. It also supports the skin's natural barrier function by reducing oxidative stress.
Pros
Gentle on skin
Low irritation and comedogenic risk makes it suitable for sensitive and acne-prone skin types.
Natural antioxidant
Derived from a common wildflower, it offers a plant-based way to fight free radicals without harsh chemicals.
Cons and cautions
Limited research
Most evidence comes from lab studies, not large human trials, so its real-world benefits are not fully proven.
Potential allergen
As a member of the Asteraceae family, it may cause allergic reactions in people sensitive to daisies, ragweed, or marigolds.
Best for
- People with sensitive or reactive skin looking for a gentle antioxidant
- Those seeking natural, plant-based skincare ingredients
Use caution if
- Individuals with known allergies to plants in the Asteraceae family (e.g., daisies, ragweed, marigolds)
