Diglucosyl Gallic Acid 98% Powder

Product Specifications / Key Facts

Key Benefits

Supports brighter, more even-looking skin — A 2022 cosmetic study found that Diglucosyl Gallic Acid improved skin brightness and reduced measured UV-spot area, melanin and erythema over time. [R5]

Acts across multiple pigmentation pathways — The same research reported tyrosinase-inhibiting activity and discusses effects on melanin transfer and pigmentation-related signaling. [R5]

Adds antioxidant support — DGA showed measurable antioxidant activity in DPPH/ABTS and reducing-power assays, although gallic acid and vitamin C were stronger in some test systems. [R5]

Offers high water compatibility — Its glycosylated structure improves formulation practicality versus many poorly water-soluble brightening actives. [R5]

Fits microbiome-aware innovation stories — The ingredient is widely associated with microbiome-activated brightening research [R7–R8]

Why Formulators Choose Diglucosyl Gallic Acid

Diglucosyl Gallic Acid combines a modern biotech story with practical water-phase formulation behavior and direct cosmetic efficacy research. Unlike many premium brighteners that require heavy solvent systems, DGA can support aqueous serums and emulsions while contributing a multi-pathway tone-care story. 

Typical Applications

• Brightening serums and essences
• Even-looking-tone creams and emulsions
• Dark-spot appearance products
• Radiance and redness-appearance care
• Multi-active biotech brightening systems
• Microbiome-inspired skin-care concepts with evidence-safe wording

Scientific Evidence Snapshot

Diglucosyl Gallic Acid has direct cosmetic research that is unusually useful for a newer biotech brightener. In a 2022 study, researchers evaluated tyrosinase inhibition, antioxidant performance and clinical cosmetic efficacy. In the 20-volunteer study, DGA-containing lotion improved skin brightness and reduced measured UV spots, melanin and erythema over time. [R5] The paper also describes DGA as water soluble and stable, and discusses partial conversion by skin-surface/stratum-corneum α-glucosidase toward gallic-acid-related activity. The clinical sample was small and should not be interpreted as a universal guarantee. More recent mixture-design research also evaluates DGA as one component in multi-active depigmentation systems, supporting its continued relevance in combination formulation. [R6]
