Product Description
The ILSO CG Toning Serum is a dual-action brightening serum featuring Collagen and Glutathione—two powerhouse ingredients for achieving luminous, youthful skin. This advanced formula combines the firming benefits of collagen with the master antioxidant glutathione for comprehensive anti-aging and tone-correcting care.
Glutathione, composed of three amino acids (glycine, cysteine, and glutamic acid), is renowned for its powerful antioxidant and brightening properties. Combined with collagen for elasticity support, this serum helps reduce dark spots, even skin tone, and protect against oxidative damage that causes premature aging.
