Alright, let's explain this, shall we?
Cosmetics are applied for facial uses, and they are only tested on specific body sections, and not necessarily with the gases used in chemicals, which may cause a crazy reaction with the cosmetics there!
Wearing gloves is only step one, but of course, that doesn't cover anything.
According to this, unfortunately, it is wrong to have any cosmetics around the lab because of the reactions with it.
Hope this helps!
If this is marked as Brainliest, i'd truly appreciate it!
