Ascorbyl Glucoside
What is it?
A stable, water-soluble vitamin C derivative that converts to ascorbic acid in the skin, used in brightening serums as a gentler alternative to pure L-ascorbic acid.
What does it do?
According to PubMed, a 2026 systematic review of 44 studies on vitamin C in dermatology describes ascorbyl glucoside, with or without arginine, as well tolerated for chronic hyperpigmentation (https://pubmed.ncbi.nlm.nih.gov/42761976/ -- no DOI listed for this article in PubMed). A separate 2026 human in vivo skin-permeation study using ToF-SIMS and OrbiSIMS imaging found ascorbyl glucoside penetrates into intracellular regions of the stratum corneum in a depth-dependent pattern, distinct from the surface-localised pattern seen for 3-O-ethyl ascorbic acid in the same study, though the study characterized permeation pathways rather than clinical efficacy (DOI: https://doi.org/10.1016/j.ijpharm.2026.127447).
