What it is
An extract obtained from the flowers of Hottonia palustris, a perennial aquatic plant native to Europe and parts of Asia. The extract contains flavonoids and other polyphenolic compounds that give it antioxidant and soothing potential.
How it works
In a cosmetic product, the extract is believed to donate electrons to neutralize free radicals (unstable molecules that can damage skin cells). It may also help calm irritated skin by reducing the activity of pro-inflammatory signals, though the exact mechanisms are not fully characterized in published studies.
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.
Antioxidant support
Contains flavonoids that may help protect skin from free radical damage caused by UV and pollution, supporting overall skin health.
Cons and cautions
Limited research
There are very few peer-reviewed studies on Hottonia palustris extract specifically for cosmetic use, so its benefits are not well-established.
Potential allergen
As with any botanical extract, there is a small risk of allergic reaction, especially for those with plant allergies.
Best for
- People with sensitive or easily irritated skin looking for a gentle soothing ingredient
- Anyone wanting a mild antioxidant boost in their routine
Use caution if
- Individuals with known allergies to aquatic plants or specific flower extracts should patch test first
Usage tips
