[Acne] Switched from the pill to Mirena 3 months ago and now almost exclusively break out on my chin. Is this hormonal?

Beauty Tips For Body Care
Hi SCA,As the title says, 3 months ago I switched from the combo pill to Mirena and since then my chin has been really the only part of my face that still breaks out. It's almost entirely cystic acne and it's painful.Has the switch in hormones caused this to happen? What can I do to minimize it, if anything?Here's my current routine: Morning: Rinse with water, apply 10% benzoyl peroxide gel to affected areas, wait to dry, then makeupEvening: Wash face with Cerave Hydrating Cleanser, then Neutrogena Clear Pore Oil-Eliminating Astringent (this is what I use for chemical exfoliation right now as I suddenly ended up at stores that didn't sell Stridex. I've been using it for 4-5 months now and it's been okay but I'm not married to it). After that dries I use the 10% benzoyl peroxide gel again, then apply facial moisturizer.It's fairly bare bones as I'm pretty new to this.Thanks for your help!
