If you're trying to solve hormonal acne, I think you should try out the pill for a few more months. I have PCOS and suffered from horrible hormonal acne. It started when I was ~11 and I had terrible, early teen level acne for the next 15 years. IUD didn't do much but the pill pretty much completely got rid of all my acne--it just took ~4-6 months to really clear up my face and then another ~6-8 months for all my deep scarring and hyperpigmentation to fade. With skincare and hormone, 1 month just isn't enough time to make a decision--your body is still getting used to the hormones.

On the other hand, if you feel terrible on it consistently, the acne may be worth it to switch back to the IUD. I also felt terrible on the pill so honestly I made the switch back after years of sacrificing my mental health for clear skin. The pill saved my life though because ~2 years on it stabilized my skin enough that my skin looks nowhere near as bad as it used to. I still get more pimples on the IUD but it's nowhere near what it used to be.
