Ingredient review
Commelina Extract
INCI: Hydrolyzed Commelina Communis Flower/Leaf/Stem Extract
A gentle, plant-based ingredient that may help calm irritated skin and provide antioxidant protection, though research is still emerging.
In plain English
This is an extract from the Commelina communis plant, also known as the dayflower. It's made by breaking down the flower, leaves, and stems into smaller pieces so they can be used in skincare. Early studies suggest it can help soothe redness and protect skin from environmental stress, but it's not as well-studied as ingredients like green tea or niacinamide.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.

lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A hydrolyzed (broken down) extract of the whole above-ground parts of the Commelina communis plant, a common wildflower in Asia. It contains flavonoids and polysaccharides believed to have soothing and antioxidant effects.
How it works
The flavonoids in Commelina extract are thought to reduce the activity of inflammatory signals in skin cells, while the polysaccharides may help form a light film that retains moisture and calms irritation. It also scavenges free radicals that can cause premature aging.
Pros
Gentle on skin
Low irritation and comedogenic risk make it suitable for sensitive and acne-prone skin types.
Antioxidant support
Flavonoids in the extract help neutralize free radicals, which can contribute to premature aging and dullness.
Cons and cautions
Limited research
Most evidence comes from lab studies or traditional use; few well-controlled human trials confirm its benefits in skincare.
Potential allergen
As a botanical extract, it may cause allergic reactions in individuals sensitive to the Commelina plant family.
Best for
- People with sensitive or easily irritated skin
- Those looking for a gentle, plant-based antioxidant
Use caution if
- Anyone with a known allergy to Commelina or related plants (Commelinaceae family)
Usage tips

Considered safe for topical use with low irritation and comedogenic potential. As with any botanical, patch testing is recommended for those with plant allergies.
