[Acne] The ONLY thing that has ever cleared my skin is soaking in mineral hot springs. How can i get the same effect at home?

Beauty Tips For Body Care
I spent a day at some hot springs while on vacation and after soaking for a few hours I noticed ALL of my zits had dried/healed, my skin was crazy smooth and balanced, and without being dramatic, it was the clearest my skin has been since before puberty. Also the effects were immediate, which basically never happens with any topical acne treatment. My body acne disappeared as well. These effects obviously didn't last long because after a few days back home my skin is back to it's inflammatory antics.Has anyone had this experience? I want to recreate the mineral content at home by buying stuff online and creating my own liquid toner/soaking solution. I did some research but all the information online is super vague so I'm not even sure what minerals are generally in hot springs to begin with. I know sulphur is definitely a healing component, as is magnesium aka epsom salt, but aside from that I have no idea what could be in the water that is clearing up my skin so effectively.About my skin: extremely oily (genetics), sensitive, inflammatory+cystic+comedonal acne, prone to hyperpigmentation.
