* An essential amino acid.


A building block of proteins, it plays a pivotal role in cell division, the healing of wounds, immune function, the release of hormones, and the production of growth hormone. The body uses it to manufacture nitrite oxide, which causes the blood vessels to relax, thereby increasing blood flow. Because it also increases the body’s fat burning & muscle building functions, coupled with the fact that the liver uses it to produce creatine, Arginine is used as a key ingredient in various weight loss & muscle building shakes.

With regards to skin care, this ingredient mainly functions as an antioxidant that helps build collagen production. It’s mainly used in anti-aging face & body products such as lotions, night creams and serums. As of yet, however, not one study can prove the skin regeneration effects of Arginine when topically applied to the skin. In fact, the most substantial evidence regarding the effects of topical amino acids on the skin comes from a 1989 study, which assessed that they may assist with hydration. There is evidence that arginine, taken orally, can speed wound healing.
