Science

Mechanism of Action

This extract operates through multiple precision pathways: its rich content of polyphenols and notably, resveratrol (reportedly 6x more concentrated than in grape seed extracts), efficiently scavenges free radicals, mitigating oxidative stress and photo-aging by absorbing UV radiation. Its significant anti-inflammatory action stems from inhibiting key inflammatory markers, trapping nitric oxide, and down-regulating the NF-κB pathway, thereby reducing the production of cytokines, chemokines, and prostaglandins in activated keratinocytes. Furthermore, it functions as an adept skin conditioning agent, promoting softness, smoothness, deep hydration, and reinforcing the skin's natural barrier function.

Key findings

  1. 01 An ethyl acetate fraction effectively inhibited TNF-α-induced increases in inflammatory markers—including cytokines, chemokines, adhesion molecules, nitric oxide, and prostaglandins—in keratinocytes, demonstrating significant anti-inflammatory potential without inducing toxicity, particularly relevant for conditions like psoriatic skin.
  2. 02 Hot water extracts, rich in stilbene monomers and derivatives such as isorhapontin (up to 12.0% dry extract), astringin (up to 4.6%), resveratrol (up to 0.3%), isorhapontigenin (up to 3.7%), and piceid (up to 3.1%), consistently exhibited both antioxidant and anti-inflammatory properties.
  3. 03 When formulated with Glycerin, this extract provided biomimetic protection against environmental aggressions, increased skin hydration, and shielded against pollution and oxidation. It also functioned as a protective shield against photo-aging by absorbing UV rays and reducing the adverse effects of UV exposure, acting as a UV protective booster.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Low

Generally recognized as safe for topical cosmetic use. Acute oral toxicity studies indicate a high safety margin, with an LD50 exceeding 2000 mg/kg for hot water extracts. EWG rates common concerns (Cancer, Allergies & Immunotoxicity, Developmental and Reproductive Toxicity, Use Restrictions) as 'LOW'. However, specific data for topical use during pregnancy and breastfeeding are limited; consultation with a healthcare professional is advised. While adverse reactions like irritation are rare, a preliminary patch test is recommended before widespread use.
