Product Description
It is a potent natural polyphenol and stilbenoid compound, primarily extracted from the heartwood of mulberry (Morus alba) and other botanical sources. This fine, white to off-white crystalline powder is characterized by its high purity, typically 98% or greater as verified by HPLC. It is the 2,3',4,5'-tetrahydroxylated derivative of resveratrol, which significantly enhances its bioactive potential.
The product is renowned for its powerful antioxidant and tyrosinase-inhibiting properties. These core functions make it a highly sought-after active ingredient in cosmetic and skincare formulations, where it effectively targets hyperpigmentation, brightens skin tone, and provides protection against oxidative stress. It is also widely researched and utilized in dietary supplements for its systemic health-supporting benefits.
Product Benefits
It offers exceptional benefits primarily as a powerful, natural skin-brightening and antioxidant agent. Its key advantage is its superior tyrosinase inhibition, effectively reducing melanin production to treat hyperpigmentation, dark spots, and promote an even, radiant skin tone. It provides strong protection against free radicals and environmental oxidative stress, helping to prevent signs of aging.
Furthermore, it possesses soothing and anti-inflammatory properties, making it suitable for sensitive skin and calming irritation. Compared to common brighteners like kojic acid, it is often gentler and more stable. These multifaceted benefits make it an ideal, high-efficacy active for targeted serums, whitening creams, and premium anti-aging skincare formulations.
