Three different actives in this serum work on skin tone through three separate pathways — niacinamide slows melanin transfer, stable vitamin C acts as an antioxidant, and tranexamic acid targets pigmentation irregularities directly. Seven European botanical extracts — from yarrow to lemon balm — enrich the formula with natural antioxidants. Hyaluronic acid binds moisture, and skin feels plumper and looks more radiant. A daily serum for those seeking a more even, vibrant-looking complexion.
