Intensive Illuminating Serum is a lightweight skin brightening formula that diminishes dull skin, evens skin tone and enhances overall clarity. Patented NIA-114 technology minimizes the effect of environmental aggressors while encapsulated skin-brightening ingredients target the key causes of discoloration. Over time, dark spots, age spots and discoloration are less visible for a more even complexion. Skin texture is smoother and more refined with a radiant, youthful glow. Allure Magazine wrote Intensive Illuminating Serum "just might be the smartest product in our medicine cabinet."
