White Balance Original Serum is a two-part, click-activated brightening system that targets the 7 causes of hyperpigmentation. The innovative formula helps to reduce the appearance of many types of pigmentation including; dark spots, age spots, blotchiness, sun damage, uneven skin tone and melasma. Using a carefully crafted selection of the best skin-brightening actives, including intelligently stabilised kojic acid, arbutin and niacinamide, the serum visibly improves concentrated areas of pigmentation to balance overall skin tone, while preventing future discolouration. Known for being difficult to stabilise, kojic acid is preserved with Medik8 Click™ technology, a unique packaging system that releases the active into the hydrating formula below just seconds before the first application, to ensure it remains potent and fresh. This beautiful formula does not include hydroquinone.
