Science

Mechanism of Action

The extract exhibits a broad spectrum of in vitro activities, including 100.0% anti-hyaluronidase, 92.7% antioxidant, 60.75% anti-elastase, 59.17% anti-inflammatory, and 30.28% anti-collagenase properties. These actions collectively contribute to preserving the skin's natural hyaluronic acid, neutralizing free radicals, protecting elastin and collagen from degradation, and mitigating inflammatory responses. This multi-targeted approach aids in skin repair and offers protection against damage from pollution and blue light.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Moderate

The CIR Panel deemed it safe for cosmetic use when formulated to be non-sensitizing. A specific maximum concentration percentage was not stipulated, as its reported cosmetic use was limited in 2021 VCRP data. Concerns exist regarding naturally occurring fragrance allergens (citronellol, geraniol); formulators are advised to ensure levels do not cause sensitization. Rigorous good manufacturing practices (cGMPs) are essential to address potential impurities such as pesticide residues and heavy metals.
