Vaseline GlutaGlow Ampoule Ultra Bright Roll-On is a dual-action underarm care product that combines the benefits of a brightening serum and deodorant in one convenient roll-on format. Featuring a concentrated formula with Niacinamide (about 3 %) and GlutaGlow technology — often blended with glutathione, collagen, and licorice extract — it helps brighten dull, uneven underarm skin and reduce dark spots over time with regular use.
