100% L-Ascorbic Acid Powder — Reddit Reviews
by The Ordinary
Updated October 3, 2026
Pure L-ascorbic acid powder brightens fast and fades dark spots; can sting.
What the community says
A 100% ascorbic acid powder you mix into another product right before applying. People use it for brightening and dark spots, but it’s fussy, can turn the face red, and isn’t for sensitive routines.
