Dark, rough patches don't just show up in one place � neck, knees, elbows and underarms all darken for the same reasons: friction, pressure and dead skin buildup. The Dark Zone Duo treats both zones with the same brightening science. The Neck, Knee & Elbow Roll-On (5% Niacinamide + Mandelic Acid) targets thick, rough, pigmented areas like the neck, knees and elbows, while the Underarm Roll-On (AHA 5% + Glutathione + Kojic Acid) treats the more delicate underarm skin with added 48-hour odour protection. Same problem, two zones � treat them together for all-over even-toned skin.
