15% ascorbyl glucoside serum for brightening; stings some users.
What the community says
A 15% ascorbyl glucoside serum with Oligopeptide-1 gives routines a gentler brightening step when stronger vitamin C feels too much. Use it every other day on dry skin; tretinoin users report stinging and should avoid stacking actives.
