>>16819You're right diet can improve acne, but the idea that acne is only caused by diet and people in cultures where they're forced to eat healthy don't have acne is bullshit. Anyone who's ever been to rural parts of Asia, Africa or South America knows this. The thing is, for documentaries or pictures and such they usually don't get that much of a close up to their skin or they simply chose the more photogenic tribal people to document. I would even argue that some tribal people even have worse acne than Americans due to lack of medical care for hormonal problems, lack of clean water and stress from lifestyle
As for older pictures, photoshop existed back then too, it just wasn't as intense as it was today. Even grandma's will straight up admit they had acne in their pictures that was edited out
