This works. I am African American and I have had acne all my life. I have many hyper-pigmentation spots from when acne had damaged my skin. Unfortunately I am allergic to benzoyl peroxide, so I am locked out of a very effective acne treatment.
Finally, I just grew fed up and started reading everything I could. I found an article that mentions acidophilus, and I remembered I got an infection last year that had me take an antibiotic. When I took it, even my wife noticed that my skin was blemish free, even though I kept having to hit the toilet. So I decided to give the acidophilus a shot. It really worked. I have not had any outbreaks for two months.
The spots where I regularly used to get outbreaks are still there, but they have not flared with inflammation. Now I am concentrating on removing the blemishes.
All I can say is good luck and try it. If it doesn't work, move on.
