CDF Kudzu Root Iso Extract™ is a standardized, puerarin-rich isoflavone active developed for modern brightening, “skin longevity,” and sensitive-skin radiance formulas. It delivers targeted tone-evening, anti-glycation support and antioxidant protection while maintaining excellent clarity and stability in water-based systems.

What It Does

Puerarin, the key isoflavone in kudzu root, helps address multiple drivers of dull, uneven, tired-looking skin. By supporting balanced pigmentation, defending against glycation-related stiffness in the dermis and providing daily antioxidant protection, CDF Kudzu Root Iso Extract™ works as a multi-functional backbone active for brightening and “skin longevity” formulations.

Key Benefits

• Dual-pathway radiance support targeting both melanin-related uneven tone and glycation-induced dullness.
• Elasticity & firmness defense by helping protect collagen from glycation stress and structural fatigue.
• Daily antioxidant protection against environmental and UV-related oxidative stress for smoother, healthier-looking skin over time.
• Sensitive-skin friendly brightening that supports tone-evening while helping calm visible redness and irritation.
• Ultra-stable, low-colour liquid that remains clear and elegant in water-based serums, essences and toners.
• Formulator-friendly profile with excellent compatibility alongside niacinamide, peptides, centella, hyaluronic acid and vitamin C derivatives.
