What is the composition of EGF(Epidermal Growth Factor)?

A neurotrophic factor that promotes the survival of various neuronal cell types and may play an important role in the injury response in the nervous system.
Just follow me to unfold the mystery of it.
EGF(Epidermal Growth Factor) is a component of the skin surface growth factor that acts on the epidermis. The components of EGF, which received the Nobel Prize in medicine, can effectively improve the skin and restore the skin improvement cycle to normal.

In a word, EGF male the skin have the ability to improve itself.EGF component decreases in our bodies with time flies. Therefore, the ability to improve gradually decreases as well.
Children and adults recover at different rates from injuries. That's also due to EGF reason.
Supplementation of EGF on such skin will be of great help to the improvement of damage.
The EGF ingredient effectively strengthens the skin barrier and helps activate the skin. Also helpful for dull, uneven skin surfaces.
Are you familiar with the composition of EGF now?
EGF is a kind of small molecular protein, widely exists in human skin extracellular matrix, is a 6.2 KDa protein containing 53 amino acid residues.
Mechanism of Action:EGF is a highly efficient cell division factor with many other biological effects, which mainly includes: 
1. stimulating the growth and proliferation of skin, cornea and racheal epithelium tissue in vivo. 
2. accelerating the healing process of epidermis damage on skin, cornea, etc. 
3. repressing the gastric acid excretion. 
4. accelerating the proliferation of epithelial cells in human and animals. 
5. facilitating the biosynthesis of protein, rna, dna as well as metabolic activity in epidermal cells.
EGF of our skin begins to decline rapidly from the beginning of 20 years old so that our skin begins to grow old as well.
But don't be disappointed.
Because many skin care products contain EGF, which can replenish the skin, as a result it will maintain the elasticity of the skin.
