In this mask, Panthenol (Vitamin B5) targets sensitivity and redness, delivering delivers deep, lasting hydration that keeps skin plump throughout the day with consistent use.

After cleansing, refine skin texture with toner, then apply the mask for 10–20 minutes. Gently pat in the remaining essence to complete multi-step hydration care in a single step, making it ideal for daily use.

Ingredients

High-purity panthenol and a pH-balanced ampoule help support long-lasting hydration and skin comfort.

Panthenol is one of the most dependable ingredients for hydration-focused skincare because it helps attract water, supports skin comfort, and works well even in routines built for sensitivity. In this mask, the formula centers on high-purity vitamin B5, or panthenol, and pairs it with a mildly acidic, pH-balancing system. That matters because very dry or easily stressed skin often responds better when moisture support is paired with a formula environment that feels balanced and low-irritation. The close-fitting cellulose sheet also improves performance by holding the ampoule evenly against the skin for the full wear time, reducing quick evaporation and helping the surface feel saturated. According to the product story, the formula is built for extended hydration rather than a short-lived wet finish, which is exactly the kind of benefit panthenol is often used to support. The overall effect is skin that looks plumper, feels less tight, and holds onto moisture more comfortably after use.
