I read on a website () that vitamin e acetate has this benefit over vitamin E:
“The ability of Tocopherol to stop the formation of peroxides is diminished by exposure to air. If you are looking for a product which stops the formation of peroxides longer, then Tocopheryl acetate (Synthetic Vitamin E) will give a longer protection, however doesn't have the 100% natural credentials that Tocopherol does.”
Is this true? I thought that the only benefit in a skincare formulation that tocopherol acetate brought was skin-conditioning. I thought it was not an antioxidant at all and that therefore it would not prevent peroxide formation in skincare formulations containing alcohols that can form peroxides.

As per the link provided by the OP, I feel that they seem confused whether even they are selling one or the other. First they talk about tocopherols, then tocopherol "active form" then tocopheryl acetate. The only reason tocopheryl acetate is preferred it's the stability against oxidation. The more stable something is, the most likely it is not to do anything in/on the skin.
There really is a lot of formulation misinformation being published. I guess it's true of probably any topic though.
Academic publishing (where there shouldn't be any monetary value attached to research, at least in principle) is not less afflicted by that. Even peer review is not able to sift through the "inflation", "non-reproducible results", or "plain lies"! I guess the monetary value in academia is each own h-index, grant funding rate, and personal publicity. It seems that everyone knows that even a minimal screw up can cost your career, and the reputation of your students/collaborators, yet people keep doing it.
I just amused myself and looked up a product I saw advertised on FB; a touted miracoulous vitamin C serum. 15% ascorbic acid in water based phase, with a pinch of hyaluronic acid and ferulic acid (1%). $150+ per 30 g (in a bottle with dropper). There is no limit to anything anymore...

Sure, it can provide an SPF value of 3.6 or 6.9.
Who cares? Modern cosmetic products minimally should give SPF 15 but better is SPF 30 or 50.
Or the Darbe paper which concluded that parabens from deodorants were somehow connected with breast cancer. Parabens aren't generally used in deodorants! There is a researcher who screwed up but just keeps plugging along.
And pointing out mistakes and exaggerations is a losing battle. There's no money in it. It takes a lot of time. And there are marketing departments who specifically benefit from the misinformation. Consumer beware.
