That’s key when vitamin C, a notoriously fickle, unstable ingredient, is concerned. “Stabilizing the vitamin C is [C E Ferulic’s] actual profit. Ascorbic acid itself is a good ingredient, but when it is breaking down, it isn’t helpful in any respect,” Dobos explains. She says that by itself, pure vitamin C would solely final a couple of week earlier than destabilizing and changing into ineffective. Dobos tells me that, in accordance with the patent, the addition of ferulic acid preserves “90 p.c of vitamin C when stability examined for one month at 45 levels Celsius [113 degrees Fahrenheit].” SkinCeuticals’ web site touts testing that discovered that its substances “stay potent to the final drop for as much as 36 months.”
SkinCeuticals patented their method when it launched and has been vigilant in defending it. Again in 2018, L’Oréal, which owns SkinCeuticals, sued Drunk Elephant, claiming that its C-Firma serum was too near C E Ferulic for consolation (the case was dismissed two years later). However patents sometimes expire after about 20 years and now different corporations will have the ability to legally attempt to replicate C E Ferulic’s potent ingredient make-up.
There are already many “dupes” for C E Ferulic, as a fast prowl by means of Reddit’s SkincareAddiction forum will inform you, however none of them may have the identical ingredient balanC E—till now. “I believe we will get loads of rivals leaping in and attempting to create a dupe product for decrease price,” Dobos speculates.
(So far as Attract is aware of, there may be thus far at the least one new C E Ferulic serum coming from one other model this 12 months, although we are able to’t share the small print but.)
However earlier than you add a brand new and cheaper C E Ferulic dupe to your Amazon cart, Dobos advises doing all of your analysis and being skeptical of manufacturers that capitalize on the patent expiry too shortly. “Are they as high-quality and secure as one thing from SkinCeuticals?” she says.
As beauty chemist Perry Romanowski factors out, having the identical ingredient make-up as SkinCeuticals’ authentic C E Ferulic doesn’t assure {that a} method may have the identical efficacy. Efficiency comes right down to the standard of the substances themselves and the product manufacturing course of, too. “Someone can put in vitamin C, not stabilize it, put within the vitamin E and ferulic acid, then say it is the identical as SkinCeuticals,” he says.
