LIGHTSKIN^® is a natural depigmenting active ingredient rich in sulfur-containing peptides. The production of these molecules has been stimulated via a unique bioguiding process of the yeast Ogataea siamensis, allowing the efficacy of the active ingredient on melanocytes to be doubled. LIGHTSKIN^® limits melanogenesis and the expression of pro-pigmenting receptors related to pollution or glycation products. Pigment defects are attenuated, complexion is lighter and more uniform, radiance is revived. Tested in Caucasian and Asian panels, LIGHTSKIN^® is recommended in all depigmenting care products.
