B-5 or pantothenic acid, can be bought at GNC in high dosage which is what is needed for severe acne. For women, any oils with omega 3, 6 or 9 (or all) can help regulate hormones. Flax seed oil, evening primrose oil - I take both, and 4 - 6 pantothenic acid caps a day. But what has really cleared my acne up - spironolactone, one month in and acne is almost gone and no more cysts.
Ask your Dr. This stuff is great for women, however men will not benefit.
Good luck
