by The Ordinary
Updated October 10, 2026
Vitamin C serum for brightening and calmer-looking skin; low-irritation daily pick.
What the community says
A lightweight vitamin C serum with ascorbyl glucoside, ergothioneine, and ginseng, meant for daytime layering under moisturizer and SPF. It suits people chasing brightness without the usual sting. Rosacea-prone skin may find it touchy.
What this means for you
What people love
Watch out for
