Ascorbyl GlucosideAntioxidant
Sugar-conjugated vitamin C. Very stable; conversion rate to active ascorbic acid is slower than other derivatives.
What it does
Ascorbyl glucoside is one of the most stable vitamin C derivatives — it tolerates a wide pH range and resists oxidation in formulation. The tradeoff is that conversion to active ascorbic acid on the skin is slower than other derivatives. Common in K-beauty brightening serums and 'sensitive skin' vitamin C products. Effects are gradual; expect 2–3 months for visible brightening.
