Radiant Tone Dual Serum Dark Spot Corrector

The Dual Serum shakes together an oil and water phase before each use, combining Thiamidol with sodium ascorbyl phosphate, a stable vitamin C derivative, and sodium hyaluronate to target dark spots while adding hydration and antioxidant support. Licorice root extract and the flavonoids glucosylrutin and isoquercitrin round out the brightening side of the formula. Like the rest of Eucerin's dark spot line, it's meant to be used daily for several weeks before results on hyperpigmentation show up.
