Sure, but it depends on what you consider to be "natural processes," and what you don't. The oxidation of sitting on a plastic^W vegan leather couch is not a "natural" process, but sitting on wood probably is. It's also not "natural" to be closed up with the results of that oxidation for most of the day, as most of our evolution happened with plenty of access to fresh air. We definitely have evidence that people were using oils and lotions for much longer than we've had modern synthetic materials or "air-tight" building methods. The science is definitely still out, but I don't think it's unreasonable to think that inhibiting this reaction might be beneficial.
