Active ingredient, preferably Lindera strychnifolia hydrolysate comprising 40% of carbohydrates, is claimed. ACTIVITY : Nootropic; Dermatological. MECHANISM OF ACTION : Clock gene expression stimulator; Collagen I synthesis stimulator; Collagen IV synthesis stimulator; Laminin 5 synthesis stimulator. The ability of the active ingredient ( Lindera strychnifolia hydrolysate) to stimulate collagen I synthesis was tested in human fibroblast. The result showed that the percentage of collagen I stimulation was 48% at a concentration of 1%, compared to control (26%).
