Curel Deep Corneum Barrier Moisture Serum for Dry & Sensitive Skin – GABAOB & Ceramide Functional Ingredient (No Alcohol) – 30ml

Curel Deep Corneum Barrier Moisture Serum is a Japanese medicated serum created for dry, sensitive skin that easily reacts to dryness, seasonal changes, and sudden environmental stress. Kao describes it as a barrier-supporting serum designed to help prevent skin irritation while delivering moisture deep into the stratum corneum and supporting clearer, more hydrated skin.

This formula features Kao’s deep barrier care approach and contains the active ingredient GABAOB (Gamma-Amino-Beta-Hydroxybutyric Acid), which helps protect the skin from external irritation and prevent roughness by supporting the barrier deep within the stratum corneum. The serum also uses Ceramide Functional Capsule Plus technology to help supplement the role of ceramides and maintain skin moisture.

The texture is described as water-based, light, and non-sticky, making it easy to use even on skin that is already prone to discomfort. Kao also positions it as a low-irritation formula for dry, sensitive skin and states that it helps support a healthy-looking, translucent complexion through better moisture retention.
