What it is
A finely ground powder from the rhizome (underground stem) of Polygonatum officinale, also known as Solomon's seal. It contains compounds like polysaccharides, saponins, and flavonoids that are thought to have soothing and antioxidant properties.
How it works
When applied to the skin, the polysaccharides in Solomon's seal powder can form a thin, film-like layer that helps retain moisture and may reduce water loss. The saponins and flavonoids may help calm irritation by interacting with skin cells to reduce redness and sensitivity. However, these effects are based on traditional use and limited lab studies, not large-scale human trials.
Pros
Gentle Soothing Potential
Traditional use and preliminary research suggest it may help calm redness and irritation, making it a good option for sensitive skin routines.
Low Irritation Risk
With a low irritation and comedogenic rating, it is unlikely to cause breakouts or stinging, even for those with reactive skin.
Cons and cautions
Limited Scientific Backing
Most evidence comes from traditional use and a few lab studies; there are no large-scale clinical trials confirming its benefits for skin.
Potential Allergen
As a botanical from the lily family, it may trigger allergic reactions in people sensitive to related plants, so patch testing is wise.
Best for
- People with sensitive or easily irritated skin looking for a gentle soothing ingredient
- Those interested in natural, plant-based skincare ingredients
Use caution if
- Individuals with known allergies to plants in the Asparagaceae or lily family should patch test first
