Incorporates the company's proprietary ingredient "Casparin R＊9" and the time-release moisturizing ingredient "Bio Saccharide Gum-1" to maintain hydration for a long time.
- Triple Up Approach
Three-Stage Drop-In
A three-step approach using large, medium, and small emulsion particles to penetrate from the surface to the depths of the stratum corneum, aiming for unprecedented smooth skin.
Three-Stage Changing Touch
From the moment it touches the skin, it provides a delightful sensation. With just one application, you can feel the freshness of toner, the softness of emulsion, and the moisture of cream.

◆ Consideration for Ease of Use
Because it is a daily-use product, we prioritize skin-friendliness by avoiding alcohol (ethanol), mineral oils, coloring agents, and fragrances.
Additionally, it has undergone patch and allergy tests. (However, it does not guarantee that irritation or allergies will not occur in all individuals.)
