Common Name(s): Fulvic acid,fulvic acid,humic substance,mineral-organic antioxidant prebiotic electrolyte
CAS Number: N/a
DESCRIPTION
What It Does: Provides antioxidant protection from fulvic acid's poly-aromatic radical scavenging, prebiotic activity for skin microbiome beneficial organisms, trace mineral bioavailability from complexation, and skin conditioning from the polyanionic humic polymer.
Why It's Used: Fulvic acid provides the most mineralogically complex antioxidant in skin care — the ancient organic matter matrix containing hundreds of condensed polyphenol structures alongside trace mineral complexes unavailable from any single botanical source.
How It Works: Fulvic acid structure: condensed polyphenol-carboxylate polymer (mw 500-2000 da) with >5 carboxyl groups per molecule. radical scavenging: extended quinone-catechol redox system providing multiple h-atom donations. mineral chelation: carboxylate and hydroxyl groups complex fe²⁺, zn²⁺, cu²⁺ for bioavailable trace mineral delivery. prebiotic: humic oligosaccharide fragments fermented by bifidobacterium.
Typically Found In: Anti-aging,microbiome,mineral skin care

SCIENTIFIC NOTE
Fulvic acid heavy metal monitoring: humic substances from soil can accumulate heavy metals (pb, as, cd) depending on soil source — cosmetic-grade fulvic acid requires icp-ms verification of heavy metal content below regulatory limits before formulation.
