You need to reduce the inflammation of the gut before the inflammation of the skin reduces; this can take many months from my experience beyond the die-off.
As long as you are going through die-off, I would think that you still have certain symptoms such as with the skin.
If my naturopath checked you out, he would give you some unda homeopathics and cataplex E. There is many more things I am sure that a naturopath would use to heal the skin woes.
If you can sweat out the toxins via the skin, this can completely cure skin problems. If you went to natural hot springs, the sulfur would would heal the skin temporarily as well.
