β-Arbutin: The Science-Backed Skin Brightener Revolutionizing Cosmetic Formulations

1. What is β-Arbutin?

β-Arbutin (4-Hydroxyphenyl-β-D-glucopyranoside) is a natural glycosylated derivative of hydroquinone that functions as a competitive tyrosinase inhibitor. Characterized by its β-configured glycosidic bond, this water-soluble compound (C₁₂H₁₆O₇) delivers targeted melanin suppression without DNA damage or cytotoxicity. As the predominant isomer in botanical sources, it achieves superior skin penetration compared to synthetic alternatives while maintaining exceptional stability at pH 4-7.

3. Efficacy, Safety & Clinical Applications

Mechanism & Benefits

• Tyrosinase Inhibition:

  • Competitive binding to Cu²⁺ active site (Kᵢ = 0.48 mM)

  • Reduces melanin synthesis by 45.8% at 0.5 mM concentration

• Antioksidantaktiwiteit:

  • ORAC value: 8,640 μmol TE/g – scavenges UV-induced ROS

• Clinical Performance:

  • 62% improvement in melasma (8-week RCT, 2% formulation)

  • Superior to kojic acid (p<0.01) with zero irritation

Dosis Aanbevelings
