How to break this cycle: Great skin before period, terrible after?

TLDR: When my period ends i get closed comedones that stay with me until my i’m PMSing. i’ve observed this for 3 cycles now, is there anything to prevent this?

So let me preface this by saying i never had full on acne, but i always dealt with closed comedones when the seasons changed and my skin care wasn’t appropriate for the climate anymore.

Now, at 33, I seem to get closed comedones on my forehead during the last days of my period. It starts with a few and gets progressively worse for around a week. For around 2 weeks they will be there, some will be shrinking, others will become inflamed whiteheads. By the time i’m PMSing, around 5-6 days before my period, my skin is the best it’s been all cycle. Then it goes downhill again.

I’m starting to wonder if there’s something i can do to prevent this. I’m waiting for a hormone test since this cycle should be reversed according to all female skincare guides i read, but it won’t be happening for another month and i have a wedding coming up right during my pimple phase.

has anyone experienced the same and been able to break this cycle? i can’t take hormonal birth control and i’m using a retinol serum und azelaic acid, but they don’t seem to prevent anything (tho i’m starting to wonder if my barrier is wrecked, but then wouldn’t i have pimples at all times?). I’d really appreciate any insight.
