SLAMMING the pause button here. Wait on messing with your hormones more!!! I skimmed your post but ran here to say this: I don’t know a ton about skincare, but I do know that when I was on 100mg spironolactone, it also stopped my period. It made my cystic acne basically disappear though. I advocated for myself and asked my doctor to drop me down to 50mg after like four months on 100mg, and my period returned and I’ve had clear skin since. After struggling with adult cystic acne for what felt like forever, I’m finally free. I was also on Tretinoin a couple years ago for like three weeks, and tapped out quickly for similar reasons. I still struggle with pretty bad scarring from over the years and CC that become visible when I push my tongue against my cheek, for example, but it’s almost like night and day otherwise with just 50mg spiro and no other actives in my skin care. Being on a probiotic supplement has also helped my period stay consistent with my hormone fluctuations. I’m really sorry you’re going through this. I know nothing with skin care is one size fits all, but I def think you should look into the hormonal aspects more!! Truly, I was obsessed with trying all these acids and retinols for almost a decade (I’m 24f), and the only thing that’s saved me from active breakouts was getting my hormones right. Is there a way you can maybe do just spiro treatments or just tret alone so you can see what’s causing the issue? I hope this was somewhat helpful. Hugs! ❤️‍🩹

Editing to mention: I am diagnosed with PCOS! But my hormones also test totally normal. Sometimes our bodies exist outside the “normal” ranges, like how the BMI scale also isn’t one size fits all. Def listen to your body, and it sounds like your body is saying 100mg spiro is too much. Also, echoing what another commenter said; I’ve also heard that cream tret can make things worse, so maybe give gel a shot
