B-5 work but if you are on the juice its not strong enough for me to break even and THEN fight acne on top of that, but I can slowly improve on it off the juice @ 12g a day split into 3 doses.
For real meds though, you are looking at anti biotics or accutane. I use accutane and it rocks, but high dose and it takes a toll on my body. I am cruising along at 20mg ED right now.
