1-38. Skin aging

When the turnover (the skin’s metabolism system) slows down, skin aging is accelerated.

Here’s another review of how skin aging works and the importance of EGF.

– Mechanism of skin aging –

Our skin renews itself in a cycle of about 45 days.
This is called the turnover time.

New skin is born in the deepest layer of the epidermis (the basal layer) and its “daughter cells” change shape to reach the surface stratum corneum and finally shed as plaque.

The turnover time increases with age.

– Necessity of EGF –

In order to make these “daughter cells”, basal cells require various “bioactive substances”.

The most important factor among them is the epidermal growth factor “EGF”.

This EGF decreases with age, leading to skin deterioration.

Therefore, actively supplementing EGF is essential for anti-aging because it can put the brakes on skin aging.

I hope you have understood the effectiveness and importance of EGF for skin aging that accelerates with age.

Again, this “EGF” is meaningless if its activity is not maintained, as its activity is very important!

Next time I’ll explain in more detail…
