Her assertion isn't backed up by any evidence, and in fact there is much documented evidence to the contrary. For example: Acne *was* present prior to the past few decades, people *are* visibly afflicted with it in photos prior to 1980, it is *not* from a single cause.

There was acne in the 90s.

It would be easy to search the history of acne. A misleading uninformed tweet. I would disregard & block a Tweet like that. Opinions on acne not the conversation I want from @Twitter website.

I don’t think people suffered from acne until relatively recently as industrial seed oils became a prominent component of modern diets If you look at images from the 80’s and 90’s, no one had acne
