Multi-Antioxidant Radiance Serum is a daily serum combining a wide range of protective technologies to combat multiple concerns associated with environmental damage and visibly brighten dull skin.. Multi-Antioxidant Radiance Serum works to combat environmental stressors, like pollution and smog, which can make skin look dull and prematurely aged. The formulation boosts radiance, while helping to fade visible dark spots and smooth the look of skin texture, all of which help to reduce the appearance of atmospheric skin aging.. Multi-Antioxidant Radiance Serum combines a total of 8 technologies, including antioxidants such as vitamin C and ginseng, to achieve a multi-faceted approach to environmental support, suited to use both in the day and at night. When used in the day, the serum-textured formulation helps shield against the damaging effects of pollution, while providing lasting hydration and barrier support for enhanced skin resilience.. When used at night, it continues to offer antioxidant protection while skin is in its resting and repair stages, working to boost radiance for skin that is visibly more radiant during the day..
