Based on microbiome-inspired science, the Clé de Peau Beauté Concentrated Brightening Serum helps to reduce the appearance of dullness, dark spots and uneven skin tone, as it unveils skin’s radiance. The brightening serum delivers up to 24-hour moisture, improving the visible clarity of skin that has been exposed to environmental aggressors such as dryness and pollution. A crystatune complex (a blend of prebiotic and eucalyptus baby leaf extract) nourishes the skin’s microbiome, while Crystallizing Power Technology works alongside a Skin-Empowering Illuminator to brighten the look of dark spots. With continued use, the serum diminishes dullness for a long-lasting lit-from-within glow.
