There is one beauty product every beauty editor uses, and it’s SkinCeuticals C E Ferulic, a magical blend of vitamins C and E and ferulic acid, all of which come together to create one of the most potent anti-aging cocktails on the market. It stimulates collagen production, and when worn under sunscreen, it boosts the SPF factor fourfold. (I also happen to think it imparts a nice dewy glow.) The formula is so exceptional it’s patented. We could sing the praises of this miracle serum all day long, but there is one caveat: The price isn’t exactly easy on the wallet. The patent hasn’t stopped other brands from trying to replicate the magic of C E Ferulic. And you may find the combination of 15% vitamin C, 1% vitamin E, and 0.5% ferulic acid in these less expensive alternatives; however, there will be two main differences between the imitators and the original.
First, SkinCeuticals uses vitamin C as L-ascorbic acid, the only form of vitamin C that prevents transepidermal water loss, meaning it keeps moisture in your skin. Other formulas may use different, more irritating forms of vitamin C, like tetrahexyldecyl ascorbate and magnesium ascorbyl palmitate. Even if they do use L-ascorbic acid, the pH of the SkinCeuticals is patented, so no other product on the market has a pH between 2.5 and 3.0. Both of these aspects affect the effectiveness, but some copycats do come close.
