JLO BEAUTY That Jlo Glow Brightening & Firming Serum with Niacinamide 30 ml Brand new. Never opened or used. Did not come in box. The name speaks for itself. This serum’s game-changer status is all thanks to a sugar-derived skin-lifting matrix, Japanese rice sake, and yeast-derived ferments, which condition and help brighten the skin for that unbridled JLo Glow™. Cruelty free.
