Glucose-stabilized vitamin C precursor; converts to L-ascorbic acid in skin via alpha-glucosidase.
Why we tier this moderate
6 cited papers across 4 countries. The mechanism is well-described and there's at least one controlled trial in the literature, but we tier this Moderate rather than Strong to stay honest about how many specific papers we cite directly.
