Poudre Cysti White - BCF Life Sciences


Given the functional properties of Traced L-Cystine, this amino acid combined with L-Glutathione as an oral dietary supplement could accelerate the production of light melanin and therefore produce a safe skin lightening effect.

To prove this, a 90-day double-blind clinical study was conducted and demonstrated that taking 750 mg of Cysti-White® daily, consisting of Traced L-Cystine combined with Glutathione, and supplemented with antioxidants, amino acids, trace elements and vitamins, significantly improves skin lightening of the face and arms and reduces the size of dark spots on the face.
