This is a high-potency vitamin tone-improving serum that targets dullness, dryness, uneven tone, and rough skin texture at the same time. Formulated with 15% high-concentration niacinamide and yuzu extract, it helps support brightening, anti-aging care, tone evenness, and hydration for an overall radiant complexion. The lightweight, hydrating texture is suitable for all skin types, and is especially ideal for dull, dry skin, leaving it looking clearer, more luminous, and comfortably moisturized with a healthy glow.
