AA2G

Ascorbyl Glucoside

A glucose-bound Vitamin C derivative that is broken down by skin enzymes into active Vitamin C over time. It is water-soluble, stable at near-neutral pH, and popular in Indian and Korean formulas for its gentleness in hot, humid climates.

Typical concentration

10–25%

Formulation pH

5–7

What AA2G is used for

  • Gradual, sustained release of active Vitamin C
  • Gentle enough for daily use in humid, sweat-prone climates
  • Good stability against light and air

Stability

Stable at pH 5–7; resists oxidation better than L-Ascorbic Acid, good for tropical storage conditions.

Advantages

  • Very stable in hot/humid climates
  • Gentle, sustained-release action
  • Widely available in Indian formulas

Limitations

  • Needs enzymatic conversion in skin, so effect is slower to show
  • Fewer large-scale clinical trials than L-Ascorbic Acid

3-O-Ethyl Ascorbic AcidRetail serums commonly list 10–15%. There is no well-established optimum from independent clinical studies, and percentages are not directly comparable with L-ascorbic acid.Does not need the very low pH that L-ascorbic acid does; formulas are usually mildly acidic
