Haven't heard of African Black soap - interested to hear success stories.
Also, since you mention the acne - your body is clearly trying to detox debris and toxins out of the body - and our skin is our largest detox organ. One thing you might also try along with the new soap is full-body detox soaks. If you already do them, switch things up by changing/increasing ingredients (most popular is sea salt, epsom salts), increasing heat and/or duration and/or frequency.
Sometimes, the acne is rooted in gut microbiome imbalance so that's something else to consider. Be sure you are on a good gut binder to help detox the gut and specifically, clear out debris and toxins that you're killing. My binder helps keep me regular, which is also very important.
Away on business a few wks ago I used this talcom powder product in my hair - because I couldn't wash it (it's tough with this IV port that I have in my chest - can't get wet, etc.) I used it a couple days in a row until I could shower. Next thing you know, I broke out all along my hairline, forehead, chin, chest, back. Not really bad but I could tell right away that something triggered it. I took a couple of high doses of the cholestyramine a few days in a row and presto - it all disappeared.
Good luck! Let us know what works -
I do appear to be having trouble detoxing - if it's coming out of my skin. I take charcoal every day. Perhaps it's not enough. I also take chanca piedra - I was taking milk thistle for a while - and I do lemon water daily, occasionally green juice, and infrared sauna once a week.
I'm not sure why it's coming out of my skin. I was also doing epsom baths until I messed up my neck.
