Well stress is linked to worsening acne as far as I know. I know I tend to break out more if I'm stressed - especially around exam time - but it's hard to say for sure that those breakouts are caused by the stress alone and not a combination of things such as lack of sleep.

So I would say that stress does play a role in acne - I doubt it would be the sole cause of anyone's acne but it might be a contributing factor.

What, exactly, is "stress?"

I'll tell you what it is - it's a made up term that has absolutely no meaning whatsoever. Everyone's definition would be different, proving my point.

well when you have anxiety most of the day and your heart is racing (like u saw a monster)

I also notice when i stress a lot, my body gets itchy (not sure if its only the acne areas that get itchy or just generally)

I suffer from chronic stress, unfortunately. Whenever I go on first dates, I break out as well...so definetely think stress is linked to acne. And I've never had a single break in mine xD
