It’s quite likely a belief that sunscreen lotion is a bad thing that harms people.
I mean, it halfway is:
“Sunscreen” – stuff with a decently high SPF rating – is a good thing that prevents cancer.
“Suntan lotion” – usually glorified coconut oil with fuck-all SPF rating – is a bad thing that harms people.
“Sunscreen lotion” – a confused amalgamation of the previous terms – is not a thing and only misleads people by conflating good things with harmful ones.

‘Lotion’ implies that it’s moisturiser-based, not that it has any tanning properties.
