ELI5: How does stress cause acne?
gpt
Acne is predominantly triggered by hormonal imbalances. When you are stressed, your body produces excess stress hormones, such as adrenaline and cortisol. 

Just imagine your computer's available memory being your skin. In order for it to run smoothly, you don't want to clog it up by running a ton of unnecessary programs. In regular use, the computer does its job by allocating memory needed to run programs and allow you to multi-task. But if you try to render a 3D-model, while playing a game at its highest settings, while bitcoin mining, while aggressively compiling that stupid powerpoint with ugly wordart, all at the same time, you stress out your computer's memory. It has a harder time allocating/managing your memory resources, just like your immune system has a harder time managing the resources necessary to clear the acne-bacteria at its normal rate.
