✦ Reihaku Hatomugi — By Kumano Cosme Japan
The moisturiser that keeps working hours after you apply it — not just while you can still feel it on your face.
Kumano Cosme has been making skincare in Japan since 1952, earning trust as a supplier to major Japanese cosmetics brands before building the Reihaku line. Their Hatomugi gel has become a go-to recommendation in Japanese pharmacies for anyone who wants serious hydration without complicated routines.
The "High" in the name isn't just marketing. This gel is built for the kind of skin that needs real moisture work — the kind that feels dry again by midday, or tight after washing, or rough in patches no amount of regular moisturiser seems to fix. The formula pairs Job's Tears Seed Extract with three types of collagen: Water-Soluble Collagen, Hydrolyzed Collagen, and Atelocollagen. Each behaves differently in the skin, which is exactly the point — they work at different depths and different speeds so the moisture effect layers rather than fades.
Isomerized Sugar (Saccharide Isomerate) is the long-acting moisturising ingredient — it binds to keratin in the skin and holds water there for hours rather than evaporating. Sodium Hyaluronate adds the immediate plumping. Arginine supports barrier function throughout. The formula is fragrance-free, alcohol-free, sulfate-free, and antioxidant-free — a genuinely clean gel that face and body both respond well to. 300g. Made in Japan.
🧴 How to Use
After cleansing and toning, apply an appropriate amount and spread over face and neck. Can be used alone as your complete moisturising step or layered under SPF. Also works on dry body areas — elbows, knees, heels. Use morning and night.
