Epidermal growth factor or EGF is a low-molecular-weight polypeptide composed of 53 amino acids that plays an important role in the regulation of cell growth, proliferation and differentiation.
History
Stanley Cohen of Vanderbilt University, who was the first to discover the EGF, won the Nobel Prize in Physiology and Medicine in 1986, but it was Greg Brown who patented EGF for cosmetic use in 1989.
Function
EGF can accelerate the growth of the epidermal cells, nervous cells and epithelial cells on organ tissues. h-EGF is an important ingredient of anti-wrinkle and anti-aging cosmetics.
EGF has been demonstrated to:
- Stimulate the growth and proliferation of skin, cornea and tracheal epithelium tissue in vivo.
- Accelerate the healing process of epidermis damage on skin, cornea, etc.
- Accelerate the proliferation of epithelial cells in human and animals.
- Facilitate 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.
