Science
Mechanism of Action
Polydatin functions as a powerful antioxidant, actively neutralizing free radicals and safeguarding the skin from UV radiation and environmental pollutants. Its anti-inflammatory action involves inhibiting key pro-inflammatory molecules like cytokines and prostaglandins, and regulating the IL-8 gene, which helps soothe inflammatory skin conditions such as eczema and psoriasis. Furthermore, Polydatin delivers anti-aging benefits by promoting collagen synthesis and inhibiting matrix metalloproteinases (MMPs), thereby reducing the appearance of fine lines and wrinkles. It contributes to a more even skin tone by inhibiting tyrosinase, an enzyme crucial for melanin production. Additionally, it enhances skin hydration and barrier function, supports cellular repair for wound healing, and provides photoprotection by maintaining mitochondrial integrity and regulating Nrf2.

Key findings
- 01 In a clinical study involving adults with atopic dermatitis, a topical polydatin cream, applied at concentrations of 0.8% and 1.5%, demonstrated significant improvement in symptoms including itching, redness, xerosis, lichenification, and eczematous lesions. Specifically, the 1.5% cream achieved an 87% reduction in itching within 7 days, progressing to 96% by 30 days, and a 78% reduction in redness at 7 days, reaching 98% by 30 days.
- 02 A separate clinical investigation confirmed the efficacy and safety of topical polydatin cream in preventing and managing papulopustular rash in cancer patients receiving EGFR inhibitors. A 1.5% concentration showed remarkable improvement in existing rashes after 4 weeks, while a 0.8% concentration was effective for preventative measures. No cutaneous adverse events were reported across any concentration group.
Transparency
Dusting Analysis
The provided research data does not contain information to suggest Polydatin is commonly 'dusted' in formulations, nor does it specify a dusting threshold or associated red flag percentages. Clinical applications have effectively utilized up to 1.5% in topical products.
The Formula
Formulation
Stability
Polydatin exhibits optimal stability within a pH range of 4.0 to 6.5. During formulation, it is crucial to avoid temperatures exceeding 40°C. For long-term storage, refrigeration in a tightly sealed container, protected from light and heat exposure, is recommended to preserve its integrity.
Safety
Safety Profile
While formal safety assessments by regulatory bodies such as CIR, SCCS, or FDA are not detailed in the available data, clinical studies reported no cutaneous adverse events related to topical polydatin application at concentrations up to 1.5%, indicating a favorable safety profile under these conditions.
