What is metabolism?
Metabolism is the process by which new cells continue to grow in the basal layer, and then push upwards to replace the outermost stratum corneum.
Metabolic cycle?
* The normal metabolic cycle is 28 days, and it often takes 14 days for new cells to be transferred upwards from the basal layer. It also takes 14 days for the stratum corneum to form and fall off. But this cycle is not fixed. A slower metabolism means that the body is gradually aging.
First of all, the 28-day epidermal passage time or epidermal replacement time is an average number, not an exact number, which means that the time of this cycle is not exactly the same for everyone.
The length of epidermal passage time or epidermal replacement time is closely related to **thickness and age. To be exact:
The epidermal turnover time of the cheek area in the 30-year-old is about 28 days.
The epidermal turnover time of infants and young children is about 14 days.
The epidermal turnover time in adolescents is between 14-28 days.
The epidermal turnover time around the age of 40 is between 28-45 days.
Before the age of 50, the epidermal renewal time increases gradually and slowly.
After the age of 50, epidermal turnover will be greatly reduced, and the epidermal turnover time will be significantly prolonged.
After the age of 50, the replacement time of the epidermis can be as long as 60-90 days.
How does metabolism manifest?
Normal metabolism is manifested as: **The surface is soft, smooth and delicate;
Metabolic abnormalities: Appears rough, dry, pigmented, prone to acne.
