When a catechin-free tea water according to the present invention is contained in a cosmetic or pharmaceutical composition, enzymes are inactivated and catechin contained in tea leaves is removed by steaming unprocessed raw tea leaves, thereby preventing the oxidation of tea water. Therefore, a composition containing the tea water according to the present invention can prevent offensive odor generation or discoloration of the composition, thereby enabling the stable use thereof in various industrial fields such as food, cosmetics and medicine. In addition, plenty of skin helpful ingredients, contained in raw tea leaves, can be contained, and thus excellent skin barrier function recovery or skin moisturization effects can be provided.
