[Usage]
EGF is a highly efficient cell division factor with many biological effects, which mainly includes:
Stimulating the growth and proliferation of skin, cornea and racheal epithelium tissue in vivo.
Accelerating the healing process of epidermis damage on skin, cornea, etc.
Accelerating the proliferation of epithelial cells in human and animals.
Facilitating the biosynthesis of protein, RNA, DNA as well as metabolic activity in epidermal cells.
Reduce and prevent lines and wrinkles by actively generating new skin cells.
Whiten skin tones with full of vitality and energy.
Eliminate scars on skin by forming new skin cells.
