ONE BY KOSÉ Serum Shield

Intensive Hydration & Wrinkle Care Balm with Rice Power® No.11+

Experience next-generation Japanese skincare with ONE BY KOSÉ Serum Shield, a medicated high-moisture sealing balm formulated with Rice Power® No.11+, Japan’s first active ingredient proven to improve skin’s moisture retention and reduce wrinkles.

This innovative treatment balm deeply hydrates dry skin while locking in moisture with a high-performance protective barrier — delivering long-lasting hydration without heaviness or stickiness.

Key Benefits

Improves Skin’s Moisture Retention

Powered by Rice Power® No.11+, this advanced ingredient helps stimulate the skin’s ability to produce ceramides, strengthening the skin barrier and improving its natural moisture-holding capacity.

The result:

• Skin that retains hydration longer

• Reduced dryness and roughness

• Softer, smoother texture

Clinically Targets Wrinkles

The formula works across multiple skin layers — the epidermis, basement membrane, and dermis — to help visibly improve the appearance of wrinkles and support healthier skin structure.

High-Moisture Sealing Balm Technology

Serum Shield features a unique high-water-content balm formula that encapsulates beauty essence within nourishing oils.

When applied to the skin, the balm melts and releases moisture-rich serum that spreads effortlessly, delivering hydration deep into the stratum corneum while forming a protective seal to prevent moisture loss.

This innovative formula provides:

• Deep hydration

• Strong moisture barrier

• Lightweight, non-greasy finish

Deep Nourishment with Advanced Delivery

The balm is enriched with carefully selected skincare ingredients and penetration-enhancing technology to deliver intensive moisture deep into the skin.

It helps improve:

• Dryness and rough texture

• Skin dullness caused by dehydration

• Skin irritation and roughness

Skin becomes smooth, radiant, and deeply hydrated.

Comfortable Texture for All Skin Types

Unlike traditional heavy balms or sticky moisturisers, Serum Shield provides rich hydration with a lightweight, comfortable finish.

Ideal for those who:

• Dislike greasy creams or oily balms

• Want deep hydration without heaviness

• Need intensive barrier repair

Fragrance

A calming green floral scent that creates a relaxing skincare experience.

How to Use

• Use morning and evening after toner.

• Apply pearl-sized amount and gently smooth over the face.

You can also use it:

• As a moisturiser instead of emulsion

• As the final step of your skincare routine
