PLEASE NOTE: In this episode, the original Skinceuticals CE Ferulic formula with only 15% ascorbic acid, 1% tocopherol, and 0.5% ferulic acid was tested for this episode. We dive into part two of our vitamin C series by putting popular C E Ferulic dupes to the test. Before revealing our side-by-side stability results, we go through a very helpful study from Slovenia examining 41 finished vitamin C products using HPLC testing to compare the quirks of various vitamin C derivatives—including L-ascorbic acid, ascorbyl glucoside, sodium ascorbyl phosphate, and 3-O-ethyl ascorbic acid. Then we go through our 8 week test findings of 7 CE Ferulic dupes and compare them to the mother formula from Skinceuticals.
