Maijun premium Gripin cream contains Gripin^® (Maitake extract), Acetyl hydroxyproline and milk ceramides. Gripin^® increases the productions of hyaluronic acid (HA) (patented process) and sebum (patent pending). Acetyl hydroxyproline works on collagen regeneration. Milk ceramides act as a moisturizing agent. So, one cream is effective for three healthy factors in the skin: H.A., sebum and collagen.
