What it is
A water- or alcohol-based extract derived from the bark of Panax notoginseng, a perennial herb in the ginseng family native to China. The bark contains active compounds like saponins (notoginsenosides), flavonoids, and polysaccharides, which are believed to contribute to its antioxidant and anti-inflammatory effects.
How it works
In a cosmetic product, Panax Notoginseng Bark Extract works primarily as an antioxidant. The saponins and flavonoids in the extract can donate electrons to unstable free radicals (like those from UV exposure or pollution), neutralizing them before they can damage skin cells. Additionally, its anti-inflammatory properties may help calm irritated skin by reducing the activity of certain inflammatory markers.
Pros
Gentle antioxidant
Provides antioxidant protection without the irritation sometimes seen with stronger actives like vitamin C, making it suitable for sensitive skin.
Soothing potential
May help calm redness and irritation, offering a dual benefit of protection and comfort in one ingredient.
Cons and cautions
Limited research
Most evidence comes from traditional use and lab studies; there are few high-quality human trials confirming its cosmetic benefits.
Variable potency
As a natural extract, its active compound levels can vary by harvest and processing, leading to inconsistent results between products.
Best for
- Anyone looking for a gentle antioxidant to protect against daily environmental damage
- People with sensitive or reactive skin who want soothing ingredients
Use caution if
- Individuals with known allergies to ginseng or related plants (Araliaceae family)
