Abstract
The present invention pertains to: a botulinum toxin, epithelial cell growth factor, or hexapeptide fusion protein bound to skin tissues and cell-permeable peptides, or an epithelial cell growth factor mixed with skin tissues and cell-permeable peptides; and a composition comprising same. The fusion protein or the epithelial cell growth factor mixed with cell-permeable peptides has increased cell permeability compared to protein by itself, and is thus useful for improving the condition of skin, treating wrinkles, relieving muscle tension, and treating wounds.
