Five month old has baby acne still!

Any idea how to help get rid of it? I wash baby’s face in morning and night. I’ve tried different soaps. I tried using just warm water for a couple weeks. I don’t use wipes on his face. When formula drips on his face I wipe it with a warm wash cloth(I use baby detergent that’s free of basically everything to wash his wash cloths and clothes) any ideas how to help it clear? I know people say it’ll eventually go away but these are the same pimples that was there two months ago. Not getting worse or better! Any ideas would be appreciated. Thank you in advanced.
