  • Patent number: 10441632
    Abstract: A method for treating wrinkle or aging on a skin of a subject includes applying to the skin a composition that includes a green fluorescent protein-human epidermal growth factor fusion protein as an effective component. Since the fusion protein has an excellent anti-oxidation activity and a high skin cell proliferation effect, it can be advantageously used as a raw material of functional cosmetics having excellent skin regeneration effect like improvement of skin wrinkles and skin whitening.
