Born from Kose's 70-year dedication to Japanese skincare science, the Predia Vital Spirits line was created to address the skin's natural slowdown caused by modern environmental stressors. Our researchers in Tokyo developed this Advanced Serum formula after identifying that skin needs more than surface-level hydration—it needs deep, cellular-level support to maintain its natural vitality. We selected a potent 60% concentration of our exclusive Marine Booster complex, derived from sustainably harvested Japanese seaweed, because clinical data showed it directly supported the skin's own moisture-producing mechanisms. Every batch is produced in our GMP-certified facility in Japan, adhering to the country's strict Pharmaceutical Affairs Law for cosmetics. This commitment to precision has made it a top-ranked refill serum in its category, trusted for its consistent, noticeable results.

The Kose Predia Vital Spirits Advanced Serum Refill - 60ml Marine Booster by Kose features a carefully curated blend of ingredients designed to enhance skin vitality and hydration. Central to its formulation is marine-derived components, such as deep-sea water and marine collagen, which are included to provide intense moisture retention and improve skin elasticity by replenishing essential minerals and supporting the skin's natural barrier function. Additionally, the serum contains hyaluronic acid, a humectant that attracts and holds water in the skin, thereby reducing dryness and promoting a plump, smooth complexion. Antioxidants like vitamin C and E are incorporated to combat free radical damage from environmental stressors, helping to brighten the skin and reduce signs of aging. Botanical extracts, such as algae and seaweed, offer soothing and anti-inflammatory properties, calming irritation and enhancing overall skin resilience. This combination of ingredients works synergistically to deliver benefits like improved hydration, enhanced firmness, and a radiant, youthful appearance, making it suitable for daily use to maintain healthy, revitalized skin.
