I used the Shea Moisture black soap, but it contained other ingredients like shea butter and it dried out my face. Now I use it on my body and it's fine.

I've used Nubian Heritage black soap on my body - never on my face. It smells great and it *usually* feels great, but Nubian Heritage sticks oats into the soap and they're basically the consistency of petrified wood. They're very hard and can sometimes scratch so I've stopped using their black soap. At the same time, using that in tandem with AHA+ has really helped reduce my body acne. Pros and cons!
