Ingredient review
Dayflower Extract
INCI: COMMELINA COMMUNIS FLOWER/LEAF/STEM EXTRACT
A gentle botanical extract with antioxidant and soothing potential, but human skin research is still limited.
In plain English
Dayflower extract comes from a plant with blue flowers that grows in many parts of Asia. In skincare, it's used to help calm irritated skin and protect against environmental damage because it contains natural antioxidants. Think of it like a mild, plant-based helper for sensitive or stressed skin, though we don't have a lot of human studies yet to confirm how well it works compared to more researched ingredients.

What it is
An extract made from the flowers, leaves, and stems of Commelina communis, a plant commonly known as dayflower or Asiatic dayflower. It contains flavonoids, phenolic acids, and other antioxidant compounds.
How it works
The flavonoids in dayflower extract help neutralize free radicals, which can damage skin cells and accelerate aging. It also appears to reduce the activity of certain inflammatory signals in the skin, potentially calming redness and irritation. In a cosmetic product, it works as a supportive ingredient rather than a primary active.
Pros
Gentle soothing potential
Early research suggests dayflower extract can help calm skin irritation, making it a good option for sensitive skin types who react to stronger actives.
Antioxidant support
Contains flavonoids that may help protect skin from daily environmental damage like pollution and UV exposure, though it should not replace sunscreen.
Cons and cautions
Limited human evidence
Most studies on dayflower extract have been done in labs or on animals, so we don't yet know how well it performs on human skin in real-world conditions.
Low typical concentration
In most products, dayflower extract is used at low levels (under 2%), so its effects are likely subtle and supportive rather than dramatic.
Best for
- People with sensitive or easily irritated skin
- Those looking for a mild antioxidant boost in their routine
Use caution if
- Anyone with a known allergy to Commelina species (rare)
Usage tips
Safety summary
Dayflower extract is considered safe for topical cosmetic use with a low risk of irritation or allergic reaction. However, as with any botanical, patch testing is recommended for those with very sensitive skin or plant allergies.
Research notes
Current evidence is mostly from in vitro (lab) and animal studies showing antioxidant and anti-inflammatory activity. Human clinical trials are lacking, so the ingredient's effectiveness in skincare remains promising but not proven.
