Kose Predia was born from a simple question: what if we could bottle the brightening power of the ocean? In Japan, where clear, luminous skin is a cultural ideal, our scientists looked to the Petite Mer—a nutrient-rich sea region. They discovered a unique mineral complex that, when concentrated, helps visibly even skin tone. This formula isn't just another toner; it's the result of over 20 years of Japanese skincare research, produced in a GMP-certified facility that meets Japan's strict pharmaceutical-grade standards. It quickly became a top-ranked brightening lotion in Japan, trusted by users who want results without harshness. We created it for anyone whose skin has lost its glow due to modern life—not because you're doing anything wrong, but because your skin needs the right, gentle support to reveal its natural clarity.

The Kose Predia Petite Mer Mineral Conc Lotion White - 170ml Brightening Toner is formulated with a blend of ingredients designed to brighten, hydrate, and refine the skin. Key components include water and butylene glycol as primary hydrating agents that enhance moisture retention and improve the penetration of other active ingredients. The toner features marine-derived elements such as seawater and algae extract, which provide essential minerals and antioxidants to nourish the skin and support its natural barrier function. For brightening purposes, it contains licorice root extract, known for its skin-lightening properties due to glabridin, which helps inhibit melanin production and reduce the appearance of dark spots. Additionally, sodium hyaluronate offers deep hydration by attracting and retaining moisture, promoting a plump and smooth complexion. The inclusion of citrus extracts, like lemon peel extract, provides vitamin C and antioxidants to combat free radicals and promote a more even skin tone. Preservatives such as phenoxyethanol ensure product stability and safety. Overall, these ingredients work synergistically to deliver a toner that hydrates, brightens, and revitalizes the skin, making it suitable for those seeking a radiant and clarified complexion.
