Breaking Out at 38

The thing nobody warned me about

I was ready for the nausea. I was ready for my clothes changing. I was not ready to be thirty-eight years old and getting the kind of breakouts along my jaw that I last had at nineteen, except now with a school run and a work camera to point them at.

My first assumption was the obvious one. New drug, new spots, drug did it. I spent an evening reading forum threads that all agreed with me, which is exactly the kind of research that feels like research and is not.

What the evidence actually says, and it surprised me

Somebody has pooled this. A 2024 meta-analysis went looking for an acne signal across six of these medications — the long-acting ones including semaglutide as Wegovy, and the short-acting ones including semaglutide as Rybelsus — and found no conclusive acne side effects reported for any of them. Its conclusion was that the drugs themselves are unlikely to be directly responsible¹.

I want to be honest about the size of that. The authors also say the literature on this is limited, which means "we did not find a signal" is not the same as "there is definitely nothing there." But it is a lot more than I had, which was a forum thread and a bad mood.

So if it is probably not the shot, what is it?

The answer that annoyed me, then helped

It is what I was eating.

Diet is one of the few things about acne with actual trial support behind it. A systematic review of 34 studies found that a high glycemic index and a higher glycemic load are associated with more acne and worse acne, and that finding is backed by randomized trials rather than just observation².

And here is the thing I had not connected. A GLP-1 changes what you eat. That is the entire point of it. In my case, four months in, nausea meant I had quietly reorganized my whole diet around what I could keep down — which was crackers, dry cereal, toast, and the occasional protein shake because I felt guilty about the crackers. I had accidentally built one of the highest-glycemic diets of my adult life, while congratulating myself on eating less.

Nobody told me that. I do not think anybody was hiding it. I just think the conversation about these drugs is so focused on how much you eat that nobody checks what is left on the plate.

What I changed

I stopped optimizing for "what will stay down" and started optimizing for "what will stay down that is not white carbohydrate." That is harder and it took a couple of weeks of experimenting. Greek yogurt worked. Eggs worked. Soup with actual things in it worked. Crackers were the easy answer and I had let the easy answer run for four months.

I also stopped treating my face like it was a side effect and started treating it like acne, which it was. There is a proper treatment guideline for this, and the things in it are the things that have always worked — benzoyl peroxide, topical retinoids, and for the hormonal kind of adult acne there are prescription options worth asking about³. That is a conversation with someone who can prescribe, not a thing to solve with a new cleanser and hope.

The part I would tell a friend

Three things.

The shot is probably not doing it directly, and I spent weeks angry at the wrong thing.

Look at what is actually on your plate now rather than how much of it there is. Mine had changed completely and I had not noticed, because the number on the scale was going the right way and I assumed that meant everything else was too.

And treat it as acne. It responds to acne treatment. Whatever started it, that part has not changed.

I am four weeks into eating differently and it is better. Not gone — better. I will take better.
