What it is
An extract derived from the flowers of Lathyrus odoratus, commonly known as sweet pea. It contains flavonoids and other phenolic compounds that give it antioxidant and soothing potential.
How it works
The flavonoids in sweet pea flower extract can neutralize free radicals, which are unstable molecules that can damage skin cells. This may help reduce oxidative stress and support a calmer, more even-looking complexion. It also provides a mild soothing effect, which can be beneficial for sensitive or irritated skin.
Pros
Gentle and soothing
Sweet pea flower extract is mild and unlikely to cause irritation, making it a good choice for sensitive skin types.
Antioxidant support
It contains flavonoids that can help protect skin from free radical damage caused by UV exposure and pollution.
Cons and cautions
Limited research
There is not enough scientific evidence to confirm how effective sweet pea extract is for skin benefits compared to more studied antioxidants.
Potential allergen
People with allergies to plants in the pea family may experience a reaction, so patch testing is recommended.
