I don't know much about acne but here's what I know about the Iodine: Iodine is the main component of the hormone produced by the thyroid gland, which regulates our metabolism - thyroid hormone accelerates cellular reactions, increases oxygen consumption and basal metabolism, and influences growth and development, energy metabolism, differentiation and protein synthesis. Healthy thyroiRAB should spill out excess Iodine. Iodine is needed by every single cell in the body and is also a component of all other hormones. Since toxic halides, such as bromine, chlorine, and perchlorate will attach to the iodine receptor sites, having a full body compliment of this element will help your body flush such toxins out of it's system. Once again I know nothing of what actually causes acne, but hopefully this might help someone who knows how acne develops create a connection.
