Hada Labo Gokujun Medicated Firming Lotion Refill (Quasi-drug) Fragrance-Free, 140ml

The active ingredient, niacinamide, is combined with three types of hyaluronic acid.
This includes low-molecular-weight elastin*2 (a moisturizing ingredient) that provides firmness to the skin, and 3D hyaluronic acid*3 (a moisturizing ingredient) that forms a moisture network on the skin.
*2 Hydrolyzed elastin
*3 Sodium hyaluronate crosspolymer
The mechanism focuses on working at the cellular level (keratinocytes) to support the foundation of the skin.
It locks in moisture, resulting in skin with a firm bounce from deep within.
*4 Stratum corneum
