  • Method of preventing or improving UV-induced skin damage using hydroangenol as active ingredient
    Patent number: 12213960
    Abstract: Provided is a method for preventing or improving UV-induced skin damage of a subject in need thereof, which comprises administering to the subject an effective amount of a composition containing hydrangenol derived from the extract of Hydrangea serrata as an active ingredient. The composition containing hydrangenol derived from the extract of Hydrangea serrata is able to increase secretion of hyaluronic acid and procollagen type-1 and inhibit secretion of MMP-1 in skin cells, and therefore effective in preventing or improving UV-induced damage of skin cells. Accordingly, the hydrangenol-containing composition is usefully available as a quasi-drug, drug, food, or cosmetic composition.
