This sounds like a good thing, in contrast to the doom-and-gloom "scary chemicals!!!11" articles that seem to have flooded journals and news in the recent years. I believe it's basically saying there is an antioxidant effect from lotions and perfumes.

Globally, PCP usage is widespread

Skimmed the article at first, and this made me chuckle. I wonder if that was deliberate.

"I believe it's basically saying there is an antioxidant effect from lotions and perfumes."

Which would be of no value.

There is no mechanism - no pathway - for ingested or applied "antioxidant" delivery into the cell where we believe we see oxidation or damage due to free radicals, etc.

... and even if there were it would probably have a terrible impact because it appears that the oxidation and free-radicals are an essential cell signaling mechanism which triggers apoptosis.

Which is a fancy way of saying: cells use these tools to kill themselves when they are performing badly. You would not want to interrupt this process.[1]
