To increase the efficacy of Crystal Tomato®, an amino acid L-Cysteine is included. Existing naturally in proteins of most living organisms, it is one of the few amino acids containing sulphur.
The sulphur allows L-Cysteine to bond in a special way to maintain the structure of proteins in the body and this helps in the formation of collagen, promoting healthy skin.
L-Cysteine also helps to boost the liver’s production of Glutathione, commonly referred to as the body’s master anti-oxidant, to maintain skin health. Without Glutathione, cells will die at a faster rate, leading to quicker ageing.
Glutathione has the ability to lighten dark skin and pigmentation, including dark acne scars, freckles, dark underarms and age spots. It does this by altering the metabolic processes of melanocytes to turn dark pigmentation (eumelanin) into light pigmentation (pheomelanin).
Although Gluthathione is commonly found in oral supplements, it is not absorbed when taken orally and has no effect on the skin*. By including L-Cysteine, a natural precursor of Glutathione in Crystal Tomato®, the natural mechanisms in the body are activated to produce its own Glutathione to improve the appearance of the skin**.
