C+C Serum — Reddit Reviews
by Stratia
Updated October 3, 2026
Silicone-heavy vitamin C blend with L-ascorbic acid and ascorbyl tetraisopalmitate; layers cleanly.
What the community says
A vitamin C serum built on silicones, L-ascorbic acid, ascorbyl tetraisopalmitate, squalane, and bisabolol. People who want a smoother, less stingy C step seem to stick with it; silicone-sensitive users may hate the feel and layering.
