Irritation risk

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

What it is

A natural extract obtained from the flowers of Lotus corniculatus, a flowering plant in the pea family. The extract contains flavonoids and phenolic compounds that are believed to have antioxidant and anti-inflammatory activity.

How it works

The flavonoids in the extract can scavenge free radicals, reducing oxidative stress on the skin. This may help protect skin cells from environmental damage and support a calmer, more even complexion. Its soothing properties are thought to come from its ability to modulate inflammatory pathways, though the exact mechanism in topical use is not fully understood.

Pros

Gentle antioxidant

Provides antioxidant benefits without common irritation, making it suitable for sensitive or reactive skin.

Soothing potential

May help calm minor redness or irritation, offering a mild anti-inflammatory effect for everyday use.

Cons and cautions

Limited research

Most evidence comes from lab studies, not large human trials, so its real-world benefits are not fully confirmed.

Low potency

Compared to more established antioxidants like vitamin C or ferulic acid, its antioxidant capacity is relatively modest.

Best for

  • Anyone looking for a mild antioxidant ingredient
  • Sensitive skin types seeking gentle soothing ingredients

Use caution if

  • Those with known allergies to plants in the Fabaceae (pea) family

Usage tips

Use in a serum or moisturizer layered under sunscreen for added antioxidant protection.
Pair with other antioxidants like vitamin E or ferulic acid for a synergistic effect.

Safety summary

Generally recognized as safe for topical cosmetic use at typical concentrations. Allergic reactions are rare but possible, especially in individuals with legume allergies. Avoid contact with eyes.

Research notes

In vitro studies show antioxidant and anti-inflammatory activity, but clinical trials on human skin are scarce. More research is needed to confirm efficacy and optimal concentrations.
