Ever since we did round 1 of our CE Ferulic dupe tests, round 2 has been highly requested. This time around, the ascorbic acid serum contenders are: La Roche Posay Pure 12% Vitamin C Serum, Wild Fleur 15% Pure Vitamin C + Xanthophyll - Marigold Brightening Serum, Cerave Vitamin C Serum, Geek & Gorgeous Vitamin C Face Serum, Prequel Lucent C, and Vichy 16% Pure Vitamin C Brightening Serum
