What the community says
A travel-friendly vitamin C serum combines 10% L-ascorbic acid with 5% ascorbyl tetraisopalmitate, plus squalane and tocopherol, in a silicone-heavy base. It suits shoppers wanting a stable antioxidant step, but layering can feel awkward and some users found results underwhelming.
