Ascorbyl Glucoside is generally a lower-concern ingredient for seborrheic dermatitis. It is a stable vitamin C derivative used for antioxidant and brightening formulas, but it is not an established seb derm treatment.

A cosmetic safety assessment supports its current uses and no ingredient-specific Malassezia concern was found. A vitamin C product can still sting inflamed skin depending on concentration, pH and the other actives or solvents, so the finished formula and your own response matter more than the ingredient name alone.
