Pterostilbene

Product Description

Pterostilbene is a next-generation, high-performance stilbenoid that represents the evolution of the celebrated antioxidant, Resveratrol. Found naturally in blueberries, this molecule is structurally similar to Resveratrol but with significantly enhanced stability and bioavailability. Its key advantage is its ability to deliver potent antioxidant and anti-inflammatory benefits more effectively to the skin, offering superior protection against the key drivers of premature aging. For formulators seeking to create cutting-edge anti-aging products with a powerful, science-backed botanical active, Pterostilbene is the superior and more reliable choice.

Product Uses

This powerful antioxidant is a cornerstone for advanced, high-efficacy anti-aging skincare:

• Anti-Aging: The ideal hero ingredient for "well-aging" serums, night creams, and protective treatments targeting oxidative stress, inflammation, and glycation.
• Protective Skincare: A key component in daily-use "anti-pollution" and preventative formulas to shield the skin from environmental damage.
• Brightening Products: Its antioxidant properties help to improve skin radiance and combat a dull complexion.

Formulation Suggestions

The recommended dosage is between 0.1-1.0%. As a powder with poor water solubility, Pterostilbene must be pre-dissolved in a suitable solvent system, such as a blend of glycols (e.g., propanediol) and ethanol, before being added to a formulation. It is best incorporated into the oil phase of an emulsion or into anhydrous systems. It works synergistically with other antioxidants like Vitamin C and Ferulic Acid to create a comprehensive protective shield for the skin. Opaque, airless packaging is recommended.
