★What are the common forms of Resveratrol Powder used in cosmetics, and which one is recommended?
Resveratrol has four isomers, divided into cis and trans forms, among which trans-Resveratrol is the most widely used in cosmetics due to its higher stability and bioactivity.
★What is the recommended addition concentration of Resveratrol Powder in cosmetic end products?
For daily basic antioxidant products (e.g., moisturizers, toners): 0.5% - 1.0% (raw powder)
For targeted anti-aging, brightening, or soothing products (e.g., serums, essences): 1.0% - 2.0%
★What cosmetic product types are suitable for adding Resveratrol Powder?
- Facial serums and essences (core application: anti-aging, brightening, soothing, and post-sun repair)
- Moisturizers and lotions (daily antioxidant and moisturizing care)
- Anti-aging creams and eye creams (targeting fine lines, wrinkles, and under-eye dullness)
- Brightening masks and sheet masks (improving uneven skin tone and dullness)
- Post-sun repair products (reducing UV-induced skin damage and inflammation)
★What formulation considerations should manufacturers pay attention to when adding Resveratrol?
- Stability protection: Resveratrol is sensitive to light, heat, and oxygen – add antioxidants (e.g., Vitamin E, ferulic acid) to the formula to enhance stability, avoid high-temperature processing (preferably below 60℃), and use opaque, sealed packaging to prevent oxidation and degradation.
Solubility improvement: Raw Resveratrol is poorly water-soluble and soluble in organic solvents (e.g., ethanol) – add appropriate solubilizers (e.g., PEG-40 hydrogenated castor oil)
- pH control: The optimal pH range for Resveratrol to exert efficacy is 5.0 - 6.5, which is consistent with the skin’s acid-base balance and helps maintain ingredient stability.
