What it is
An extract made from the flowers of Grevillea speciosa, a plant native to Australia. It contains various plant compounds, including flavonoids and phenolic acids, which are known for their antioxidant activity.
How it works
The extract is thought to work by donating electrons to neutralize free radicals—unstable molecules that can damage skin cells and accelerate aging. It may also have mild soothing properties due to its natural anti-inflammatory compounds.
Pros
Natural antioxidant source
Contains flavonoids that can help neutralize free radicals, potentially reducing oxidative stress on the skin.
Low irritation potential
Generally well-tolerated, making it suitable for sensitive skin types when used at typical concentrations.
Cons and cautions
Limited skin research
Most evidence comes from general plant chemistry; specific studies on human skin are scarce, so benefits are not well-documented.
Variable potency
As a natural extract, its active compound levels can vary by harvest and processing, leading to inconsistent results.
Best for
- Anyone looking for a gentle, natural antioxidant
- Those with normal to dry skin who want extra environmental protection
Use caution if
- People with known allergies to Grevillea or related plants
