The concept of removing toxins from your body. Some skin-care products claim they can “detox” you, but that’s not really how it works. In reality, detox products generally just remove dead skin cells and excess oil. Detoxification or detoxication (detox for short) is the physiological or medicinal removal of toxic substances from a living organism, including the human body, which is mainly carried out by the liver. Additionally, it can refer to the period of drug withdrawal during which an organism returns to homeostasis after long-term use of an addictive substance. In medicine, detoxification can be achieved by decontamination of poison ingestion and the use of antidotes as well as techniques such as dialysis and (in a limited number of cases) chelation therapy. Many alternative medicine practitioners promote various types of detoxification such as detoxification diets. Scientists have described these as a "waste of time and money". Sense About Science, a UK-based charitable trust, determined that most such dietary "detox" claims lack any supporting evidence. The liver and kidney are naturally capable of detox, as are intracellular (specifically, inner membrane of mitochondria or in the endoplasmic reticulum of cells) proteins such as CYP enzymes. In cases of kidney failure, the action of the kidneys is mimicked by dialysis; kidney and liver transplants are also used for kidney and liver failure, respectively.
