JM Solution's Marine Luminous Pearl mask is a Korean sheet mask built around deep-sea water, marine collagen, and pearl extract to give a deep hydration boost and a brighter, more radiant look. The essence also carries hyaluronic acid and seaweed extracts (including Laminaria Japonica and Codium Fragile) to help plump and soften the skin. It is well suited for dry, dull, or tired-looking skin that needs an instant moisture and glow top-up. To use, unfold the sheet, apply it to a cleansed face, leave on for 15-20 minutes, then remove and gently pat in the remaining essence. Great as an occasional treatment before an event or as part of a regular hydration routine. One of many variants in JM Solution's popular mask lineup from Korea.
