What it is
A water-soluble extract derived from the root of Melothria heterophylla, a plant in the cucumber family. It contains natural compounds like flavonoids and saponins that are thought to have antioxidant and anti-inflammatory activity.
How it works
In a cosmetic product, this extract works by donating electrons to neutralize free radicals (unstable molecules that can damage skin cells) and by calming inflammatory pathways in the skin. This can help reduce visible redness and support a more even skin tone over time.
Pros
Gentle on skin
With a low irritation and comedogenic risk, this extract is suitable for most skin types, including sensitive and acne-prone skin.
Natural antioxidant
It provides a plant-based way to fight free radicals, which can help slow signs of aging caused by pollution and UV exposure.
Cons and cautions
Limited research
Most evidence comes from lab studies, not large human trials, so the real-world benefits are not yet fully proven.
Potential allergen
As a botanical extract, it may cause allergic reactions in people sensitive to related plants like cucumbers or melons.
Best for
- People with sensitive or easily irritated skin
- Those looking for a natural antioxidant to complement their routine
Use caution if
- Individuals with a known allergy to cucumbers or melons should patch test first
