The luxury original: Paula's Choice C15 Super Booster 15% Vitamin C Serum, $44.25

What matches: The same vitamin C recipe: 15% L-ascorbic acid in water with ethoxydiglycol, ferulic acid and ergothioneine, the antioxidant both brands say keeps the vitamin C working, plus mannitol.

What it does worse: Paula's Choice adds vitamin E, two peptides and hyaluronic acid, and Prequel adds niacinamide and inulin but no vitamin E.
