Adenosine Triphosphate Best Antioxidant Soothing Anti-Ageing Adenosine Triphosphate at a glance Also called ATP Present in all living cells Soothing ingredient and antioxidant Provides energy for numerous body functions Ruled safe as used in cosmetics Adenosine Triphosphate description Adenosine triphosphate, also referred to by its initials ATP, is a type of molecule found within the cells of all living tissue. It is a nucleotide, which means it is a combination of a nitrogenous base (adenine), a sugar (ribose), and a phosphate (triphosphate). In the human body, ATP provides energy to support numerous functions, including muscle contraction and the synthesis of chemicals the body requires to maintain health. In skin care products, adenosine triphosphate provides soothing benefits. Since it’s also an antioxidant, it helps fight free-radical damage that can cause signs of aging. There is also mounting evidence that topically applied ATP can fight inflammation, in part because the body (including skin’s uppermost layers) has adenosine receptors. The independent Cosmetic Ingredient Review panel has ruled adenosine triphosphate safe in its current practices and usages. The typical range of adenosine triphosphate used in cosmetics is typically 0.1–0.5% when part of a blend.
