It was discovered that patients on high dose Glutathione therapy had significant skin lightening as a side effect. Now this has become a fast growing treatment for cosmetic purposes. Injectable Glutathione has become more popular than tablets and are given intravenously 2 – 3 times a week for about 6 months. The digestive tract is bypassed and the maximum concentration reaches the target cells. Results are more dramatic in lighter skinned individuals and it is common to augment results with chemical peels. Glutathione is also known for its anti-aging benefits.
Glutathione acts to lighten skin by inhibiting Tyrosinase the enzyme responsible for the production of the pigment Melanin without destroying the pigment producing cells known as Melanocytes.
