Suggest Treatment For Dark Patches On Face

Hey, I used nadinola fade cream once at night on my face, then I woke up the next morning with big rashes/tiny bumps on my face..I started to use my salicylic face scrub an ointment to help it but the patches got rough,bigger and dark..the patches burn when I wash my face. I try to keep it moisturize but everything I use on my face give me pimples-causing dark spots. I'm currently using black soap to wash my face with an shea butter to moisturize the patches on my face. How to get rid of this the right way an get my skin back healthy?
