Description

One By Kose Serum Shield 40g is a serum-cream hybrid moisturiser for dry skin β€” combining serum absorption speed with cream-level moisture sealing using Rice Power No.11+ as the key barrier ingredient. The "Shield" designation reflects its focus on protecting the moisture barrier rather than simply adding surface moisture.

  • Rice Power No.11+ β€” Kose proprietary fermented rice extract that supports the skin's own moisture retention capacity within the stratum corneum
  • Hydration barrier ingredients β€” reduce transepidermal water loss for sustained comfort between applications
  • Serum-in-cream texture β€” spreads quickly, absorbs to provide cream-level barrier sealing
  • 40g β€” standard serum-cream size

How it works: Rice Power No.11+ supports production and retention of ceramides and barrier lipids within the stratum corneum β€” improving the skin's own moisture-locking capacity rather than only adding moisture externally. The serum-cream format provides both quick absorption and sustained barrier protection.

One By Kose vs Sekkisei Brightening Cream (both Kose): One By Kose focuses on barrier repair and moisture retention through Rice Power No.11+. Sekkisei focuses on botanical brightening through Angelica Root and Melothria. Choose One By Kose for moisture barrier repair as the primary need; Sekkisei for brightening and luminosity alongside moisture.

Known in Japan as ONE BY KOSE セラム シールド 40g.

The formula is certified by dermatologist testing for reduced irritation risk and is available exclusively through the Japanese domestic market. For skin where moisture barrier function is measurably declining and standard moisturisers no longer maintain comfortable hydration between applications, One By Kose Serum Shield targets the underlying barrier capacity issue rather than only supplementing surface hydration.
