SkinCeuticals C E Ferulic has a substantial research reputation. But one of the broadest descriptions of that record does not come from SkinCeuticals itself.
Veriphy Skincare has described C E Ferulic as having been “referenced in over 100 peer-reviewed studies” and as “one of the most researched products in the industry.”
But substantiating those claims requires more than the accepted record provides. The accepted record does not provide the list of studies behind the figure, define what counts as a “reference,” or show how products across the industry were compared.
SkinCeuticals has made a different claim. In a July 2026 announcement, the company said C E Ferulic was backed by more than 20 years of research and over 30 peer-reviewed publications. It also described the serum as having “the most extensive body of clinical evidence of any topical antioxidant serum.”
The two sets of numbers cannot simply be treated as different ways of saying the same thing. One refers to more than 100 peer-reviewed studies in which the product was reportedly referenced; the other to more than 30 peer-reviewed publications. The accepted evidence provides no method for reconciling them. And SkinCeuticals’ comparison is specifically with other topical antioxidant serums, not products across the industry generally.
There is, however, direct historical research behind a CEFer formulation associated with C E Ferulic. A 2008 experiment applied a formulation containing 15% L-ascorbic acid, 1% alpha-tocopherol and 0.5% ferulic acid to human skin and compared it with a vehicle before simulated UV exposure.

That is direct experimental evidence, rather than simply a reference to the product in a publication. But it is also more limited than the broad research reputation might suggest.
SkinCeuticals announced a next-generation C E Ferulic formula in July 2026 that retained those three antioxidants while adding carnosine and Endophytol™. The accepted record does not connect the historical study formulation to the current U.S. Product Version, nor does it identify a study directly testing the reformulated 2026 product.
So the distinction matters: C E Ferulic has a documented research history, including historical experimental evidence. What the accepted record does not substantiate is the broader third-party characterisation that it has been referenced in more than 100 peer-reviewed studies and ranks among the industry’s most researched products.
