While placenta is extracted from the placentas of mammals—including pigs, horses, and cows, as well as humans—there are potential risks of infection. These include residual hormones, hepatitis B and C viruses, various bacteria, HIV, and prions (the pathogen responsible for Mad Cow Disease).

Skin turnover refers to the natural renewal cycle of the stratum corneum (the outermost layer of the skin). While typically known to take about 28 days, this process gradually slows down with age.

As we age, our bodies undergo a process of aging, which is essentially our cells ‘rusting’ from active oxygen—much like metal. This ‘rusting’ or oxidation is caused by active oxygen (free radicals). Active oxygen is constantly being produced in our bodies through the oxygen we breathe. When it accumulates, it does not just accelerate aging; it is also known to trigger various diseases, such as promoting the growth of cancer cells and causing arteriosclerosis.

However, since oxygen is essential for survival, our bodies are naturally equipped with substances to block this active oxygen. These are known as ‘antioxidants’ (or scavengers), and their defense mechanism is what we call ‘antioxidant power.’

EGF is one of several cytokines. It is a type of protein naturally produced in the body, officially known as Epidermal Growth Factor. True to its name, it is a factor that stimulates the proliferation and growth of epithelial—specifically, skin—cells.

By binding to specific receptors on the skin, EGF transmits signals to the surrounding cellular tissue, repairing aging signs such as wounds and wrinkles to deliver powerful anti-aging benefits. Also referred to as human oligopeptide, Human Epidermal Growth Factor is commonly abbreviated as ‘hEGF’ or ‘EGF.’ It was discovered by Dr. Stanley Cohen of the United States, who famously received the Nobel Prize in Physiology or Medicine in 1986 for this groundbreaking discovery.
