Timeless Skin Care 20% Vitamin C + E Ferulic Acid Serum
$28 — save $51 (65%) vs $79
The Scoop
Timeless uses the gold-standard trio C-Firma is built on — L-ascorbic acid, vitamin E, and ferulic acid — at a straight 20% concentration. Same antioxidant chemistry, same brightening and firming target, same morning-serum slot in a routine, at roughly a third of the price.
Key Differences
C-Firma adds fruit enzymes and a nutrient blend on top of the core actives, and its packaging protects the formula better; pure L-AA serums like Timeless oxidize faster once opened, so buy small and use it within a few months.
