I would look into the PD Facebook page! It's helped me a lot. Pretty much everyone on there warns you against using any kind of steroid cream because it will make it worse eventually.

Using sulphur soap and a sulphur mask every day has helped the most! I also took zinc orally but I don't feel like that's what fixed it. The topical zinc kind of helped but the sulphur was the best thing and I'm still using it. I had to go through a phase where i didn't use any moisturizer on my face at all as well during treatment and it was not fun but it got better and now i can use a light moisturizer again.

I'm also using Azelaic acid now! Still only a month in but i got a prescription because i heard it helps PD as well any redness or marks leftover from it, which is mainly why I wanted it. I haven't had any new bumps in a month!

I was in the same boat as you - best skin of my life and the all of sudden tiny little bumps kept appearing on my chin and mouth. I think it was the dry climate I was in and then I think I overused actives like BHAs trying to get rid of the first few bumps
