What it is
Brasenia schreberi leaf extract is a botanical ingredient derived from the leaves of the water shield plant, a perennial aquatic herb native to Asia and North America. The extract is rich in bioactive compounds such as flavonoids, tannins, and polysaccharides, which contribute to its antioxidant and anti-inflammatory properties.
How it works
In a cosmetic product, Brasenia schreberi leaf extract works primarily by delivering antioxidants that neutralize free radicals from UV and pollution, and by providing polysaccharides that form a thin, soothing film on the skin. This film can help reduce transepidermal water loss (TEWL) and calm irritation, making the skin feel more comfortable and less reactive.
Pros
Gentle soothing effect
The polysaccharides in the extract help calm redness and irritation, making it suitable for reactive skin types.
Antioxidant protection
Flavonoids in the extract help neutralize free radicals, potentially reducing damage from UV and pollution over time.
Cons and cautions
Limited human research
Most evidence comes from lab or animal studies; large-scale human trials confirming its benefits are still scarce.
Potential for rare allergies
As with any botanical, a small number of people may experience contact dermatitis or allergic reactions.
Best for
- People with sensitive or easily irritated skin
- Those looking for lightweight antioxidant protection in serums or moisturizers
Use caution if
- Individuals with known allergies to aquatic plants or specific botanical extracts
