Glutathione is an antioxidant that is naturally produced by the body.
It is made up of three amino acids: cysteine, glutamate, and glycine. Some people use glutathione supplements or topical products in an attempt to lighten their skin, as it is thought that the antioxidant may help to inhibit the production of melanin, the pigment that gives color to the skin, hair, and eyes.
Taking it in pill form seems to be the most popular due to the convenience and not needing to add more steps to your skin regime. Ultimately, the effectiveness of glutathione for skin lightening will depend on the individual person and their specific skin care needs and concerns.
It is important to note that the effectiveness of any skin care treatment can vary from person to person, and there is no one-size-fits-all solution for improving and evening out skin tone.
But Glutathione is the go to supplement when it comes to lightening skin tone, and is a must in your supplement stack if this is your goal.
