Everyday, women are smearing formaldehyde on their body...story time. I bought a new construction house a few years back and have been paranoid about formaldehyde. Prior to moving into it, I bought a formaldehyde detector. I had it on at my old house just for kicks. Once in a while, it would reach high values and flash red with a death symbol (no joke). We realized it flashed red whenever my wife was putting on cosmetics. It contains an ingredient called DMDM hydantoin (https://en.wikipedia.org/wiki/DMDM_hydantoin https://en.wikipedia.org/wiki/DMDM_hydantoin) which is basically a slow release formaldehyde, which prevents bacteria growth on the cosmetics. You can argue it's minute amount...maybe. But certainly enough for a detector to detect it after dispersion from across the room. Shampoo has it too. I've since checked for this ingredient prior to buying anything, and probably substituting for another bad chemical.
