Science

Mechanism of Action

This extract actively mitigates oxidative stress by neutralizing free radicals and diminishing malondialdehyde levels, while simultaneously enhancing the activity of key antioxidant enzymes like superoxide dismutase, catalase, and glutathione peroxidase. Its anti-inflammatory action stems from a demonstrated ability to suppress IL-6 secretion and inhibit nitric oxide production. Furthermore, it is understood to support collagen synthesis, thereby contributing to enhanced skin elasticity and firmness, and aids in maintaining skin hydration and promoting repair processes. Tyrosinase inhibition suggests a mechanism for addressing hyperpigmentation.

Safety Profile

CIR Status
Not reviewed
Sensitization risk Moderate

Direct review by CIR or SCCS is currently unavailable. Commercial data suggests a 'risk factor of 1' and no acne-causing properties. However, it is important to note that for other species within the Polygonum genus, patch tests are advised for individuals with sensitive skin, due to isolated reports of allergic reactions such as rashes and itching. While concerning ingestible forms, unprocessed Polygonatum herbs are noted to potentially irritate the throat, a risk mitigated by processing.
